1.2 Features

The ZIP4x4 is a SIP based IP phone with a large number of features. The top of the phone is shown in figure 1-1 and the bottom of the phone in figure 1-2. The phone is referred to as a “four by four” because it has four call appearances and four Ethernet circuits.

Figure 1-1 Top View of ZIP 4x4

Key features of the phone are:

• four virtual lines support four simultaneous calls

• headset, handset, and speaker modes

• acoustic echo cancellation in speaker mode provides high quality speaker phone

1. Introduction

Figure 1-2 Bottom View of ZIP 4x4

• four 10/100Base-T Ethernet circuits to connect to the LAN and three additional devices such as

a desktop PC, a notebook PC, and another accessory

• supports all commonly used PBX functions when used in conjunction with an appropriate call

control system

• supports IEEE 802.1q VLAN tagging and IEEE 802.1p priority marking so it can be used with

any switch

• receives power over Ethernet (IEEE 802.3af) or from ac adapter

• speech encryption ensures that your calls can be kept secure

• easy to create conferences with three to five people, including those who call you

• 35 buttons (11 with LEDs) give significant ease of use

• 3 line x 20 character display is easy to read (5 mm high characters)

• uses standard SIP messages to interface to a variety of call managers from various

manufacturers

• dial by number or SIP address

• built in switch can forward traffic at line speeds and supports QoS and VLAN tagging

• complete calculator function

• hot key dialling

• critical operational parameters are protected by password

ZIP4x4 User’s Manual

• 100 memory phone book plus 64 location memory for last numbers received or dialled

• based on highly stable Linux operating system

1.2.1 Switch Functionality

The phone uses an Ethernet switch (not a hub) to connect the three accessory ports and the phone itself to the LAN. Therefore, the ZIP4x4 can control the QoS to ensure that voice packets always have priority. Further, when the phone is not in use, the ZIP4x4 supports wire speed switching between the LAN (network) and the accessory ports. A conceptual picture of the switch is shown in figure 1-3.

Figure 1-3 Internal Representation of the Managed Switch

You can put the phone and the accessory ports on different VLANs (802.1q – see section 9.6.4 on page 139 for details).

The inclusion of the switch inside the phone allows you to take a single Ethernet circuit from the wiring closet to the desktop. If you are connecting multiple users and not computers, you can use this internal switch to make connections to other phones. You can connect phones two layers deep with this arrangement to minimize the number of switch ports required in the wiring closet.

1.2.2 Display Description

The display is a graphical LCD, 160 dots by 32 dots. It is used mostly to display characters, 20 columns by 3 rows. You can tilt the display so that it is facing you. Pull the back of the display unit and swing it up and towards the front of the phone, as shown in figure 1-4.

You can adjust the contrast of the display as described in section 9.5.1 on page 120.

1. Introduction

Figure 1-4 Showing how you can tilt the LCD for better viewing

1.2.3 LEDs

The phone has eight bi-color LEDs and three red LEDs. The bi-color LEDs can be off, or show red, green, or orange. These LEDs are on the four call buttons and the four buttons immediately above them. The red LEDs are on the speaker key, the mute button, and the park button.

1.2.4 Instruction Card

The phone has an instruction card on the bottom. Slide out the card using the tab to see brief instructions on how to use the phone.

2.4 Training

Zultys offers training at its facility in California. Contact your Zultys sales representative for current pricing. If you have purchased your the ZIP4x4 from a distributor located either within or outside the USA, contact your distributor about equivalent services that they may offer locally.

Training is not included in the purchase price of your system, and you must pay for these services (and any applicable travel expenses) separately.

The training at Zultys's facility is a two day course. The purpose of the course is to teach you how to use the ZIP4x4, so that you can leave the classroom and apply your knowledge to your specific deployment of the product. The course teaches you about installation, provisioning, system administration, and maintenance.

2.5 Software Updates

2.5.1 General

The majority of features in the ZIP4x4 are provided by software. Newer versions of the software may contain more features.

You can identify the version of the software from the menu (described in chapter 9.4.4, starting on page 119), under Information.

Zultys posts versions of its software on its web site at:

http://www.zultys.com

The information on the web site tells you what new features are included in the latest software release.

2. Warranty, Service, and Support

2.5.2 Released and Pre-Released Software

Released software has been fully tested by Zultys and by selected customers of Zultys. When you take delivery of an the ZIP4x4, you receive the latest released software. Zultys issues a new release of software about once a year.

Pre-released software has been partially tested. Zultys distributes this software to support new features or functions requested by customers. Pre-releases may also contain fixes to some known bugs. Zultys may distribute dozens of versions of pre-released software between formal releases. However, Zultys restricts the circulation of these pre-released versions. When you use pre-released software, you are acknowledging that Zultys has not fully tested the software version.

If you have chosen to install pre-release software on your phone, you should do so only if you think that the use of the increased features outweigh the risks associated with using software that has not been fully tested. Zultys documents the new or enhanced features in the updated version of this manual, and does not usually make printed documentation immediately available.

2.5.3 Software Subscriptions

You may need to purchase a software subscription separately from your purchase of the product. When you buy a subscription, it covers your ZIP4x4 for a period of one year. The software subscription entitles you to software updates that may include new or enhanced features, problem fixes, or both. Zultys alone will determine in what way a new release is different from an older release. Zultys alone will determine the number of such updates that it will distribute during any twelve-month period, including none. However, Zultys usually offers one formal release within a twelve-month period.

ZIP4x4 User’s Manual

When you have a current software subscription for your the ZIP4x4, you are entitled to download software from the web site. All software that is posted on Zultys’ web site requires a password before you can install it on your system. Zultys supplies you with the password when you purchase a subscription. The password expires at the end of the subscription period unless you renew the subscription.

Zultys may determine that some functions of the ZIP 4x4 will be sold separately as software licenses. If you have purchased software licenses, the software subscription includes updates to those software options.

The price for the software subscription is different depending on whether you purchase the subscription at the time you place an order for the system, during a period of coverage, or at a time when you no longer have coverage. Contact your Zultys sales representative for current pricing.

The software subscription (or an extension of software subscription) applies to an individual phone. If you have more than one ZIP4x4, and you wish to operate all phones on the latest software, you should have a current subscription for each system. You may not update the software on those phones for which the software subscription has expired.

As of the time of writing this manual, Zultys has determined that all software updates for the ZIP4x4 are currently available at no charge. You should check the ZIP4x4 web site periodically if you are interested in software updates. Zultys reserves the right to charge for software updates at a future date.

2.6 Support

2.6.1 Resources

This section suggests ways to save yourself time by checking for answers yourself and ruling out common problems.

If you have a question about the way the ZIP4x4 works, the best way to get an accurate, immediate answer is to try one or all of these approaches first.

• Review the User’s Guide for the ZIP4x4.

• Check the index or table of contents of this manual for the topic you need.

• See the ZIP4x4 technical support information and FAQ pages on the ZIP4x4 web site:

If you take these steps and still cannot find the answer, contact your sales representative, distributor, or Zultys.

2.6.2 Contacting your Reseller

If you brought your product from a reseller and not directly from Zultys, you should contact them first about questions related to the product. The reseller that sold the product to you has charged you money for this support and you should therefore expect that they will assist you.

Often, a reseller will provide you a maintenance contract as part of your purchase, so that the reseller will support you for a period of time after you receive the product. Verify with your purchasing department to see if you have a support contract for your ZIP4x4.

If the reseller is unable or unwilling to assist you, or if you bought the product directly from Zultys, you should contact Zultys’ technical support directly.

2.6.3 Using Zultys’ Technical Support

Zultys provides you with 30 days free technical support with the purchase of a phone. The period of technical support starts on the first day that you make a call to technical support and ends on the 30th calendar day from the first time that you called.

Zultys generally ceases to support old versions of the software six months after a new release is available. If the software subscription for your phone has expired, or you have not upgraded your phone to the latest software release after six months of the release date, Zultys’ technical support may not be able to assist you.

2.6.3.1 Technical Support by E-Mail

Often, Zultys's technical support will need to know exactly how your phone is configured. You should send this information to Zultys’ technical support using e-mail to:

support@Zultys.com

If possible, Zultys’ technical support will resolve your problem efficiently by e-mail. If the problem cannot be resolved by e-mail, Zultys’ technical support will call you or wait for you to call them.

2. Warranty, Service, and Support

2.6.3.2 Calling Technical Support

Be prepared when you call. When you call to speak to Zultys's technical support, you will get an immediate resolution to your problem if you are ready with certain types of information:

1. Send details of your configuration in advance of calling. Allow Zultys’ technical support at least four hours to review your e-mail. In your e-mail, state what it is that you think is wrong.

2. When you call, ensure you have your ZIP4x4 close by.

3. Ensure that your surrounding area is quiet, and that you can hear the technical support

person.

4. Zultys’ technical support can assist you best if you are ready to describe the sequence that led to the problem.

5. Know exactly what you did before the problem occurred, and the exact wording of any message appearing on the LCD.

6. Have a pen or pencil and paper ready to take notes.

2.6.3.3 Support vs. Training

The ZIP4x4 is an advanced phone that requires detailed technical knowledge of data communications and telecommunications to configure. It is easy for you to modify parameters so that the ZIP4x4 does not behave in the manner that you expect.

The onus is on you, the system administrator, to configure the ZIP4x4 the way you want it. Zultys’ technical support is not a substitute for training or commissioning. If you need training on the product, join one of Zultys’ training courses (see section 2.4 on page 12 for details). Use Zultys’ technical support to solve problems that you have tried diligently to solve by yourself.

Your local Zultys sales representative will arrange for repair or replacement, at Zultys’s discretion. In certain cases, Zultys may require a claim settlement.

3.4 Returning Items for Repair or Replacement

3.4.1 Warranty Coverage

Before returning merchandise to Zultys for repair or replacement, you must ensure that the items are under warranty. Read chapter 2, starting on page 9, for details on the warranty of Zultys’s products. If you are unsure about the warranty of your merchandise, call your local Zultys sales representative for clarification. You must obtain an RMA before returning any merchandise from Zultys; this includes equipment covered under warranty.

For merchandise not under warranty, Zultys offers extended warranty. Call your local Zultys sales representative for pricing on extended warranty for your merchandise.

3.4.2 Obtaining RMA Number

If you believe that something is wrong with the equipment, call Zultys’s inside sales department to obtain a return merchandise authorization (RMA) number. If the problem is technical in nature, Zultys may first try to diagnose the problem over the telephone. If the problem cannot be resolved over the telephone, Zultys will issue an RMA number and give you specific instructions for the return of the merchandise to Zultys’s facilities.

If you have purchased Zultys’s products through a distributor outside the US, contact the distributor for specific instructions. Zultys issues RMA numbers for customers who buy its products directly from Zultys. Distributors will offer their own service and support for Zultys’s products.

3.4.3 Describing the Problem

If you are returning equipment to Zultys for service, attach a tag or sheet of paper to the equipment giving the following details:

• your company or institution’s name, address, and phone number

• the main person to contact, an alternative contact, and their phone numbers if different from

the main phone number

• the return shipping address and any special shipping instructions

• the model number and serial number of the equipment being returned

• a description of the failure (If failure is intermittent, describe its frequency and special

condition that initiate the failure.)

• any additional comments

3. Receiving the ZIP4x4

3.4.4 Accessories

Do not return any of the accessories with the equipment unless you suspect that one of them is faulty. If you return an accessory, place a tag on it that clearly identifies it as yours, and briefly explain the problem.

3.4.5 Packing

Wherever possible, use the original packing materials to ship the equipment. If these are not available, containers and cushioning material similar to those originally used are available from Zultys.

If it is inconvenient to obtain supplies from Zultys, use a strong, double-walled shipping carton. Place about 70 mm (3 in) of cushioning material around all sides of the equipment.

Zultys is not responsible for any damage that occurs during shipment back to the factory.

3.4.6 Shipping

Obtain from your nearest Zultys sales or service representative the correct address to which you should return the equipment. Clearly mark the container with Zultys’s address and your own address. Ship the package prepaid and insured to Zultys.

The method of shipment which Zultys will return repaired merchandise back to your facility will be the same method by which you shipped the merchandise to Zultys. For example, if you shipped merchandise to Zultys by ground shipment, Zultys will return the merchandise to you by ground shipment. If the merchandise must be repaired and returned to you as soon as possible, you must arrange for the merchandise to be shipped to Zultys by overnight shipment.

Installation

4.1 Preparing the ZIP4x4 for Use

4.1.1 Handset

Connect the handset to the bottom of the phone as identified in figure 1-2. Trap the cord in the clips at the back of the phone to relieve strain on the connector and to allow the cord to exit neatly to the left of the phone.

4.1.2 Power

You can power the ZIP 4x4 from an ac supply or from the network.

4.1.2.1 Power over Ethernet

If you ordered the phone without an ac adapter you must ensure that you connect the ZIP4x4 to an Ethernet switch that provides power as per IEEE 802. port labelled LAN. The cable length can be 100 m, the maximum allowed for an unpowered Ethernet circuit.

3af.

The ZIP4x4 takes its power from the

4.1.2.2 Power from an AC Adapter

If you have ordered the phone with an ac adapter, you should use it regardless whether power is provided over the Ethernet connection. Connect the ac adapter to the bottom of the phone as identified in figure 1-2. The plug is at a right angle to the cord so that if you accidentally pull the phone, the cord does not fall out.

1. The ZIP4x4 is fully compliant with IEE 802.3af and is a device that consumes “half power” as defined by the specification.

2. You should use one of the ac adapters provided by Zultys. If you are unable to obtain this, use an adapter that has a dc output of 12 V, 600 mA. The plug should be 2.0 mm or 2.1 mm with the center positive. Zultys does not warrant operation of the ZIP4x4 with any adapters other than those supplied by Zultys.

ZIP4x4 User’s Manual

4.1.2.3 Dual Power Sources

If the phone receives power from both the Ethernet port and an ac adapter, it consumes power only from the ac adapter. You can see what power is applied to the ZIP4x4 using the menu. See section 9.4.3 on page 117.

If the ac power fails, the phone can take power from a LAN power source and continue to operate. The length of time that the phone will operate with the power from the LAN is dependent on the capacity of the battery connected to the power source and the number of phones drawing power. Using the phone to make a call does not materially change the power used by the phone.

4.1.2.4 When Power is Applied

When you apply power, the phone starts to operate. The ZIP 4x4 does not have any power switch. After the phone is powered up, it displays a message on the screen as shown in section 4.2 on page

26.

4.1.3 Wall or Desk Mounting

You can mount the phone on a wall or on a desk. Install the rear platform that has the two back feet if you are putting the phone on a desk. Remove this platform (as shown in figure 1-2) if you want to mount the phone on the wall, and mount it in the lower position.

4.1.4 Connecting to the Network

You normally connect the ZIP4x4 to a LAN or directly to a call control system. The call control system manages many function for the phone including the ability to originate and terminate a call, and provides a storage for voice mail. This section briefly describes the process of connecting the phone to a network.

Section 8.2.9 on page 79 describes the method of directly connecting two ZIP4x4 phones, either outside of a LAN or isolated within a network.

4.1.4.1 Auto MDI/MDI-X and Auto Negotiation

Each of the four Ethernet circuits on the ZIP4x4 has automatic sensing to determine on which pins of the RJ45 connector it should transmit data and on which pins of the RJ45 connector it should receive data. This is referred to as auto MDI/MDI-X.

With this function in the phone, you can use a straight or cross wired cable to connect the phone to any other device. If you connect the phone to a device that itself has auto MDI/MDI-X, the devices resolve the appropriate pins to use through random selection.

Also, each of the four Ethernet circuits on the ZIP4x4 has automatic sensing to determine whether the circuit should operate at 10Mb/s or 100 Mb/s. The phone will always attempt to establish connection at the higher rate and will fall back to the lower rate only if the device to which you have connected the phone cannot operate at the higher rate.

4.1.4.2 Single Circuit

Connect the LAN circuit on the back of the phone to the LAN, as shown in figure 4-1.

4. Installation

Figure 4-1 Connecting the ZIP4x4 and Your PC

You may have a router or switch to which you connect the phone. Whatever connectivity exists between the phone and the SIP server, ensure that you use the LAN port to perform the uplink.

Connect your PC or notebook to any of the other three circuits (P1, P2, or P3). You can identify if the phone has connectivity and activity on any of the circuits as described in section 9.4.3 on page

117.

4.1.4.3 Cascading

The ZIP4x4 has a very efficient network switch incorporated in it so you can cascade the phones as shown in figure 4-2.

Connect the LAN port on the phone to the LAN and connect other phones to the other ports. Connect your PC to the fourth port. You can use any of the ports P1, P2, and P3 for the other phones or your PC.

At the second phone in the chain, connect the LAN port to the first phone in the chain. The first phone can obtain power from the LAN through the first phone. The ZIP4x4 does not propagate the power to any of the ports P1, P2, or P3. Therefore, a phone connected to one of these ports must obtain its power from an ac adapter.

Although you can continue to cascade phones in this manner, it is not recommended that you do so. The network may be difficult to manage and may have poor performance.

Once you have made the connections, you can identify if a phone has connectivity and activity on any of its circuits as described in section 9.4.3 on page 117.

1. If you do not use VLANs on the phone, and if you do not expect the phone to receive power from the network, you can actually use any port to connect to the phone system. In this case, the switch inside the ZIP4x4 is an unmanaged switch and it does not matter to which port you connect. However, the phone must have connectivity on the port marked LAN and always using this to connect to the network ensures that you have a consistent network that is easier to maintain.

• Rated Output: 12.5 mW

• Impedance (Z

): 32 ohms

• Microphone Type: condenser

• Connector Type: 2.5 mm mono phone jack

Tip – Microphone

Ring – Speaker

Sleeve – Ground

Zultys supplies a headset with the phone, but you can buy good quality replacement headsets for about $20.

Traditionally, headsets have been designed to plug in series with the handset. These also provide good quality but typically cost $120.

With the ZIP4x4 you can choose either type of headset. Switching between the headset, handset, and speaker is described in section 8.1.1 on page 71.

4.1.5.1 Using the Audio Connector

The connector on the side of the phone is a 2.5 mm socket. Connect the headset that came with the phone or an alternative standard headset into this socket.

Do not buy a headset that has two connectors. These are normally used to connect to the sound ports of a PC. Those connectors are 3.5 mm.

Figure 4-3 Connecting a Headset to the ZIP4x4 Using the Audio Connector

4.1.5.2 Using an External Switch Box

You can connect a headset in series with the handset connector as shown in figure 4-4. The switch box usually has an amplifier that is powered either from an ac outlet or from batteries. This box allows you to select between using the handset and using the headset.

4.2.5 Communicating with the Network

4.2.5.1 Phone Not Connected

If the phone is not connected on its LAN circuit, the phone displays:

ZIP4x4 SIP Phone

Phone not connected

4.2.5.2 Connecting to a DHCP Server

If the phone is configured for dynamic IP addressing, it attempts to locate a DHCP server. The phone displays:

Looking for DHCP

••••••••

Depending on your network, this can take from two to 30 seconds. The phone displays a progress bar, adding one character every second. It displays the time it has been trying in the lower right corner of the display, in hours, minutes, and seconds. Every 20 s, the phone clears the progress bar then starts adding one character each second again.

00:08

The phone continues to try to find the DHCP server indefinitely.

4.2.5.3 Connecting to the TFTP Server

Once the phone has its IP address, it tries to locate the TFTP server if it is programmed with the address of the TFTP server or if it obtained the address from the DHCP server. The phone displays:

Looking for TFTP

•••

Depending on your network, this can take from one to ten seconds. The phone displays a progress bar, adding one character every second. It displays the time it has been trying in the lower right corner of the display, in seconds.

If the phone can find the TFTP server, the configuration file or files it retrieves may indicate that the phone needs to update its software. See section 5.3.5 on page 42 for details of the screen that the phone shows in this case.

If the phone can find the TFTP server but cannot find the configuration file (or it can find it, but there is an error with it), the phone displays:

ZIP4x4 SIP Phone Unable to read configuration file

00:03

The phone displays this for three seconds and then proceeds to register.

The phone continues to try to find the TFTP server for ten seconds. If it cannot locate the TFTP server within this time, and the phone has the address of a SIP registrar, it displays

ZIP4x4 SIP Phone Unable to locate TFTP server

The phone displays this for three seconds and then proceeds to register.

4.2.5.4 Connecting to the SIP Registrar

If the phone has an address for the SIP registrar, it displays:

SIP registration

The phone continues to attempt to register indefinitely. If the SIP registrar rejects the attempt to register, the phone displays:

4. Installation

00:06

SIP registration

Rejected 02:17

4.2.5.5 Failure When Using a Fixed IP Address

If you have configured the phone to use a fixed IP address, and to not use DHCP, the phone should boot up and connect to the TFTP server (if provisioned) and then connect to the SIP registrar. If there is a problem with this process, the phone displays:

Failed to initialize network. Correct settings and reboot.

Use the menu to configure the protected settings as described in section 9.6 on page 131, then restart the phone.

The phone will also display this message if you have configured it for DHCP but the DHCP server is incorrectly configured. This is an unusual situation, because administrators take great care to ensure that the DHCP servers are correctly configured.

4.2.5.6 Prohibition on Making a Call

When there is one or more of the problems listed above, the phone flashes the LEDs orange on the Call buttons. It flashes the first button for 250 ms, then the second for 250 ms, and so on, to give the appearance of a “walking” pattern. The LEDs on the call buttons remain in this state, the call buttons are inoperative, the phone does not provide dial tone, and you cannot make any calls until you have resolved the problem.

ZIP4x4 User’s Manual

You can use other functions of the phone. Therefore you can change the configuration and the settings, view or modify the phone book, and use the calculator. Once you press keys to activate the other functions, the display removes the notification of the error condition. You need to use the menu to access the status as described in section 9.4.3 on page 117.

4.2.5.7 Attempt to Establish Connection

The phone continually tries to re-establish connection with the network, once every four seconds. buttons and you can use the phone to make calls. You do not need to cycle the power on the phone to make the phone usable.

The phone retains the display until you press a key or until you make a call or the phone receives a call. You need to use the menu to access the status as described in section 9.4.3 on page 117.

If it does establish connection, it stops the walking pattern on the call appearance

4.2.6 Satisfactory Connections

4.2.6.1 Date and Time

Your ZIP4x4 may prompt you for the date and time. The prompts that you see are based on the system to which the phone is connected. Many systems may automatically configure the time, date, and geographic location of your phone. Other systems may connect your phone directly to an NTP server.

If the phone connects to an NTP server, it needs to know the difference between the local time and GMT.

Instead of asking for a location, the phone therefore displays:

Enter difference in time from GMT }-8:00

Use the Up and Down buttons or the Up and Down keys to select the correct time difference. The phone changes the time in units of 30 minutes. The maximum time differences are +12 hours and –12 hours. When you have made your entry, press the Enter button. The phone shows the idle display.

If the phone cannot find an NTP server, you must enter the date and time manually. The ZIP 4x4 displays:

Enter date Year: }2003

Use the Up and Down buttons or the Up and Down keys to select the correct year. The phone defaults to 2002 scrolls to a maximum of 2022, then to 2002 again.

1. The ZIP4x4 sends the second request 500 ms after the first request. It sends the third request 1.0 s after that, the fourth request 2.0 s after that, and thereafter every four seconds.

2. After the phone has booted it uses SNTP to obtain the date and time for the first time. Thereafter, it uses NTP every ten to 15 minutes to obtain the date and time.

4. Installation

Press the Enter button. The phone displays:

Enter date Month: }January

Use the Up and Down buttons or the Up and Down keys to scroll between the months.

Press the Enter button. The phone displays:

Enter date Day: }1

Use the Up and Down buttons or the Up and Down keys to scroll between the days. The phone scrolls back to 1 once it has reached 28, 29, 30, or 31, depending on the year and month you have entered.

Press the Enter button. The phone displays:

Enter time }15:08:39

Enter the time with the keypad using 24 hour notation. that separates hours from minutes and minutes from seconds. You do not have to enter the seconds. If you do not enter the seconds, the ZIP4x4 sets the seconds to zero.

Press the Enter button when you have entered the time. The phone shows the idle display, as described in section 6.3.1 on page 48.

You can subsequently alter the date and time using the menu as described in section 9.5.4 on page 122, or you can cycle power on the phone to obtain the same screen.

4.2.6.2 Subsequent Loss of Connection

If the phone has established LAN connectivity and registered with the phone system, and then it loses connectivity, or a subsequent registration request is denied, you cannot make calls. The phone remains in this state as described in section 4.2.5.6 on page 31.

Use the * key to enter the colon character

1. Use 24 hour notation regardless of the format you may have chosen in which time is displayed in section 9.5.7 on page

127.

Chapter 5

Provisioning the Phone

5.1 Introduction

This and the following two sections (section 5.2 and section 5.3) describe the method used by the ZIP4x4 to automatically obtain its configuration. These sections describe the underlying method for the exchanges that take place. You do not need to read these sections unless you want to understand the provisioning process, or make the ZIP4x4 work with a particular SIP system.

5.1.1 Summary of Boot Process

To use the ZIP4x4 in its usual manner, you must connect the phone to a LAN that has a DHCP server and a TFTP server. The start up process is as follows:

1. The DHCP server provides an IP address to the phone and also the address of the TFTP server.

2. The phone accesses the TFTP server to locate a configuration file that is common for all ZIP4x4 phones connected to your network.

3. The phone reads the common configuration file. The configuration file points to a directory where the phone can find its specific configuration file.

4. The phone reads its specific configuration file.

5. The phone uses the data retrieved from the configuration files to configure itself so that it

can operate properly in the network.

5.1.1.1 DHCP Support

When you connect the ZIP4x4 phone to a DHCP server, the DHCP server must be configured with the following options for your network to fully support the ZIP4x4:

• subnet mask (option 1)

• default gateway (option 3)

• domain name server (option 6)

• IP Address (option 50)

• TFTP server name (option 66)

In addition, it is recommended that your DHCP server also provide:

• NTP Time Offset (option 2)

ZIP4x4 User’s Manual

• domain name (option 15)

• NTP servers (option 42)

You should consult your system administrator for specific details on configuration of the DHCP server.

5.2 Configuration Files

There can be three sources of configuration for the phone:

• what is saved in a common configuration file

• what is saved in a specific configuration file

• what is saved in the phone’s memory

The common configuration file is called:

ZIP4x4_common.cfg

This file is stored in the root directory of the TFTP server.

The specific configuration file is called:

<MAC address>.cfg

For example,

0050C2180FD8.cfg

The format for the files is identical, and is shown in figure 5-1. This is an ASCII text file, with the name of the parameter and the value of the parameter listed on the same line. Each parameter must be within the section (denoted by square brackets “[]”). The contents of the file are not case sensitive; you can enter parameter names in upper or lower case. Comment lines are denoted with a leading semi-colon (;) and have no effect on the operation of the phone.

Figure 5-1 Format for Configuration File (Continued)

Many parameters in the configuration files correspond to the parameters that you can configure through the menu of the ZIP4x4. Configuration parameters are described in Appendix C, starting on page 161.

Every time the phone restarts (either by command or by power on), the phone reads the configuration files. It extracts the data in the files and saves it to memory, overwriting all parameters that are saved in memory except that if the user settings are not configured to be cleared, it retains the settings in the phone.

The common configuration file specifies a directory, using the parameter:

tftp_cfg_dir= <directory_name>

The phone accesses the specified directory (which can be blank, or ‘.’) and reads the specific configuration file from the specified directory. It extracts the data in the file and saves it to memory, overwriting whatever parameters were already saved in memory. The parameters specified in the specific configuration file take precedence over the same parameters specified in the common configuration file.

For example, suppose the common configuration specifies the greeting message to be:

1. You select whether you want the user settings cleared using the menu, as described in section 9.5.3.

2. If the specific configuration file contains such a line, the phone ignores it.

ZIP 4x4 SIP Phone

and the specific configuration specifies the greeting message to be:

Freddy Phone

Then, in the idle state, the phone will display:

Freddy Phone

Wed 20 Nov 02 14:50

The phone continues to start, using the parameters that are now saved in its memory.

5.3 Updating Software on the ZIP4x4

5.3.1 Introduction

You must connect the phone to a LAN that has a TFTP server and a DHCP server.1 The DHCP server provides an IP address to the phone and also the address of the TFTP server. The phone accesses the TFTP server to locate and retrieve its configuration files. It reads the configuration files to identify what software version it should be using. If the files specify a different version from that on the phone, the phone retrieves the specified software version from the TFTP server.

5. Provisioning the Phone

5.3.2 Specific Description

To update the software, one or both of the configuration files described in section 5.2 must specify the software version that the phone must use. This is specified on the line shown in figure 5-2 as:

software_version=0.1.4

The phone compares the version specified to that installed on the phone. If the versions are the same, the phone continues with the startup process. If the versions are different, the phone retrieves the software from the TFTP site. The phone looks first in the root directory of the TFTP site then in the subdirectory of the TFTP site where the specific configuration file may be stored, if one is specified.

The software name is:

ZIP4x4_<version>.bin

For example:

ZIP4x4_0_1_4.bin

The file name uses the underscore character to separate the three parts of the software version number.

1. You cannot update the software if you fix the IP address of the phone.

ZIP4x4 User’s Manual

If the common configuration file indicates a different version of the software than the specific configuration file, the phone retrieves the software version specified by the specific configuration file.

The phone programs itself with the new software and restarts.

5.3.3 Binary File

The binary file for the software contains the software version. When the ZIP4x4 reads the file, it verifies the version that is contained in the file with the file name and will not load it if the versions do not match.

The first characters in the binary file are encoded as a null terminated ASCII string. The end of the file contains a 16 bit CRC sum check.

The size of the binary file is between 2 MB and 4 MB.

5.3.4 Ladder Diagram

Figure 5-2 shows the messages used in this process. The following sections describe the process.

5.3.4.1 Step 1

Action. ZIP4x4 sends DHCP DISCOVER (broadcast)

Description. The ZIP4x4 boots (after power is initially applied or after receiving a SIP NOTIFY

message) and sends out a DHCP DISCOVER message requesting an IP Address and other options (same as those provided in DHCP ACK).

5.3.4.2 Step 2

Action. DHCP Server responds with a DHCP OFFER

Description. The DHCP Server indicates an available IP Address to the ZIP4x4.

5.3.4.3 Step 3

Action. ZIP4x4 sends DHCP REQUEST (broadcast)

Description. The ZIP4x4 accepts the DHCP server’s offer and asks the server to provide its

configuration.

5.3.4.4 Step 4

Action. DHCP Server sends DHCP ACK

Description. DHCP Server responds with committed IP Address and other configuration options.

The specific options needed by the ZIP4x4 are described in section 5.1.1.1.

5.3.4.5 Step 5

Action. ZIP4x4 initiates TFTP read request for ZIP 4x4_common.cfg

Description. ZIP4x4 requests its common configuration file using the TFTP Server address

provided by DHCP option #66.

5.3.4.6 Step 6

Action. ZIP4x4 receives TFTP data (ZIP 4x4_common.cfg) from the TFTP Server

Description. The ZIP4x4 receives the common configuration file and reads it. It is possible that the

specific configuration file for a phone is located in a directory that is not the TFTP root directory. If this is the case, the subdirectory is indicated in this common configuration file.

5.3.4.7 Step 7

Action. ZIP4x4 initiates TFTP read request for MAC_address.cfg

Description. The ZIP4x4 requests its specific configuration file. The specific configuration file is

uniquely named with the specific MAC address of the phone (for example, 0008A10FF312.cfg).

5.3.4.8 Step 8

Action. ZIP4x4 receives TFTP data (MAC_address.cfg) from the TFTP Server

Description. The ZIP4x4 reads its specific configuration file and determines whether its software

version matches that specified. If not, it retrieves the new software.

5.3.4.9 Step 9

Action. ZIP4x4 initiates TFTP read request for ZIP 4x4_version bin.

Description. The ZIP4x4 requests the specific software version using the TFTP Server address

provided by DHCP option #66 (for example, ZIP4x4_0_1_34.bin).

5.3.4.10 Step 10

Action. The ZIP4x4 receives TFTP data (ZIP 4x4_version.bin) from the TFTP Server

Description. After downloading the software version the ZIP4x4 reboots and repeats all of the

steps (except for retrieving software). At this point, the ZIP4x4 performs a checksum verification and compares the new software version file name with the version information stored internally to the .bin file. If the checksum fails or if the file name does not match that of the version information stored internally to the .bin file, the phone indicates an error and loads the previous software version.

5.3.5 Summary

For a user, the process of updating the software is fully automatic. The administrator of the network can initiate this process at any time. When the phone is idle, it will start the process of updating the software. Usually, the administrator would cause this to happen when no one is likely to want to use the phone.

5. Provisioning the Phone

To start the update process, the software in the phone restarts and displays:

U pd a ti n g s o ft w ar e

. .. . .. . .. . . .

The phone displays this message using different characters than normal, and only two lines of text. It shows the progress of the update on the second line using periods (full stops). There are 20 characters on the line and each period indicates the phone has completed about 5% of the programming task. The phone shows a new period every one to three seconds.

Important Do not disturb the phone during the update process. You cannot use the phone

to make or receive calls while the software is being updated. This process takes about 30 seconds.

When the phone has provisioned the software, it restarts itself, just as it does when you power it on. After about 15 seconds the phone displays the idle display and is ready to use.

If the software update process fails, the phone may display:

U pd a ti n g s o ft w ar e

F ai l ed . .. . . .

The phone displays this message if it found the software file but the file had been corrupted. Contact the system administrator to resolve this. You will not be able to use the phone until you resolve the problem.

ZIP4x4 User’s Manual

Chapter 6

Interacting with the Phone

6.1 Call Appearances

The ZIP4x4 has four call appearances. Each call appearance allows you to have a separate or joined call.

This type of phone is different from phones that have been in common use for the past 100 years. On those older phones a physical pair (or two pairs) of wires carry a single voice call. A phone that can accommodate two voice calls connects to two such circuits, with each circuit being referred to as a line. A switch on the phone selects between the lines (and therefore with whom you are talking). A phone that has four lines has four such sets of circuits and can allow four simultaneous calls.

The ZIP4x4 has a single circuit to connect to the switch. All calls take place over this same circuit, or line. Dedicated software and hardware inside the phone and the switch permit you to have four simultaneous conversations. These are referred to as four calls, not four lines.

6.2 Using the Keypad and the Buttons

The term buttons refers to the switches that are identified by the writing on a label below them, shown in figure 6-1.

Figure 6-1 View of Buttons on ZIP4x4

The term keypad refers to the switches that have writing on them, shown in figure 6-2.

ZIP4x4 User’s Manual

Figure 6-2 View of Keys on ZIP4x4

6.2.1 Description of Keypad

6.2.1.1 Numerals and Dedicated Keys

The keypad has keys labelled 0 to 9, *, and #. These are used to dial a number and perform other functions. The keypad has keys that are dedicated to specific purposes identified by the text on the key.

6.2.1.2 Function Key

The keypad has a key marked Func that serves as a function, or shift, key to select alternative uses for the keys and buttons. To select the alternative use, press and release the Func button once, then press the appropriate button or key to select the alternative function.

Important Do not press the Func key and another button or key simultaneously. The ZIP4x4

can read only a single button or key being pressed at a time.

The Func key is green and the label on the card that shows the alternative function of the button is also green. If you cannot distinguish between these colors, the alternative use is written to the right of the standard use.

For example, to select the calculator mode, press Func then the button marked Mem and Calc. To exit calculator mode, repeat this sequence. In subsequent sections of this document, the text does not describe this sequence. That is, the text states, for example:

“To enter calculator mode, press Calc”

This saves writing:

“To enter calculator mode, press Func then Mem | Calc”

6.2.1.3 Volume Keys

The volume keys are identified by the double arrows on the wide button. You press the up arrow to increase the volume and the down arrow to decrease the volume. The keys are used for other functions depending on the mode.

When you change the volume, the phone remembers the value you set and uses it in the future. When you power down the phone and restore power, the phone retains the same setting. There are five individual volume settings:

1. When the phone is idle, the volume keys control the volume of the ringer. When you press the keys, the phone plays the ringer tone that you have currently selected. You can adjust the volume to suit your needs. After you stop pressing the key, the ZIP4x4 continues to play the ringer tone for two seconds.

2. When you are using the handset, the volume keys control the volume at which you hear the speech from the other party through the earpiece.

6. Interacting with the Phone

3. When you are using the headset as shown in figure 4-3 on page 25, the volume keys control the volume at which you hear the speech from the other party through the earpiece.

4. When you are using the headset as shown in section 4-4 on page 25, the volume keys control the volume at which you hear the speech from the other party through the earpiece.

5. When you are using the speaker, the volume keys control the volume at which you hear the speech from the other party through the speaker.

When you adjust the volume of the headset, ensure that you have the handset on the cradle. The phone adjusts the level for the correct external headset (through a switch box or through an audio connector) depending if you have plugged a headset into the audio connector or not.

Each volume control has twenty one settings, numbered 0 to 20. When you adjust the level, the display shows:

Volume: Speaker 7

••••••••••••••

The bar at the bottom of the display represents the volume graphically, from 0 to 20. When the volume is at 0, the sound is completely turned off.

The volume control does not alter the level of the sound at which that the phone sends its signal to the network.

1. Section 9.6.6 on page 143 describes how you select the tone that is played when the phone rings.

ZIP4x4 User’s Manual

6.2.2 Description of Buttons

The buttons are used to access features or functions of the phone or phone system easily. You use the buttons labelled Call 1, Call 2, Call 3, and Call 4 to make, receive, and terminate calls. The other eleven buttons have two purposes, depending if you pressed the Func key before you pressed the button.

To access the secondary function of a button, press and release Func then press the button. If you do not press a button within 2½ seconds, the shift function is inoperative, so that when you press a button you will select the standard use for the button not the secondary function.

If you select the Func key in error, you can cancel it by pressing Func again.

When you press the Func key, it does not lock the selection of secondary use of the buttons. Therefore, if you want to select another secondary function, you must press the Func button again. For example, suppose you want to enter calculator mode and then want to pick up a previously parked call. You would press:

You use the top row of buttons to navigate the menu as described in section 6.3.3 on page 49. When you press Func before you press one of the buttons on the top row, the phone dials a number that you have stored in memory locations 01 to 05.

The use of each of the buttons is described in later sections.

Func, Mem | Calc, Func, Park | Pickup

6.3 Basics of Display Organization

The LCD is used to display information and configuration.

The top row of buttons provide access to the menu so you can configure the phone. From the menu you can also view information about the phone. Some buttons directly affect the operation of the phone or the way the phone interacts with the phone system.

As you make or receive calls, or affect the operation of the phone, the LCD shows the status of the calls or interaction with the system.

6.3.1 Idle

When the phone is idle:

• each of the call appearance LEDs is off

• the phone displays a greeting message on the first row of the display

• the phone displays the date and time on the third row of the display

For example:

Sales support

Sun 31 Aug 02 20:31

1. The Func key is described in section 6.2.1.2 on page 46.

2. This behavior is different from when you are dialling and use the Func key to select alternative use for the keys.

3. See section 8.7.3 on page 96 for more details.

You can program the greeting message and the format in which the date and time are shown.1

6.3.2 Incoming Call

When your ZIP4x4 receives a call, the phone displays:

The phone shows:

• the call appearance number (1 to 4 instead of ‘x’)

• the name of the intended recipient of the call (on the first line)

• the name or phone number of the caller if available

6.3.3 Menu

6. Interacting with the Phone

x: To <your_name> <caller’s name or number>

6.3.3.1 Introduction

This section describes how to access and exit the menu. Section 9.1 on page 107 describes the menu structure.

6.3.3.2 Accessing and Exiting

You access the configuration by pressing the Menu button. You can access the menu only when the phone is on hook and is idle (no calls in progress or connected). As soon as you press the Menu button, the LED on the speaker key and the Mute button flash synchronously. They flash red for 250 ms and are off for 750 ms to inform you that you are accessing the menu.

To exit the menu, press the Menu button again or any call appearance button. If you do not press any keys or buttons for 60 seconds, the phone automatically exits the Menu mode.

6.3.3.3 Navigating

When you have accessed the menu, you then use the Enter, Esc, Up, and Down buttons to navigate through the menu.

When you are accessing the menu, you can use the volume keys instead of the up and down buttons. The key for increase is equivalent to Up and the key for decrease is equivalent to Down.

1. See section 9.5.2 on page 121 and section 9.5.7 on page 127 for details.

ZIP4x4 User’s Manual

6.3.3.4 Display on LCD

When you access the menu, the top row on the LCD shows the menu item. The second and third rows show menu choices. The currently selected item has an arrow in the first row of the display. An example is shown:

When you press the Down button, the arrow moves down, so the above screen would look like:

When you press the Down button again, the ZIP4x4 displays the next menu item, keeping the arrow on the bottom row:

As you continue to press the Up button, the ZIP4x4 shows each of the menu selections in turn, wrapping round to the last menu selection once it has displayed the first.

To select the item pointed to by the arrow, press the Enter button. This action may also show an item further into the menu structure, or it may move you up one item in the menu structure. The top row on the LCD informs you where you are in the menu structure.

To move back through the menu structure press the Esc button. If you point to an item in the menu that you want to select and press Esc instead of Enter, the phone does not change the value of the parameter.

For example, if you pressed the Enter button when the display was as above, you would select the country to be Canada, and the display would change to:

Set | Regional Optn }country

language

When you next enter a menu, the ZIP4x4 puts the arrow in the second row and points to the currently selected item. For example, in the example above, if you pressed the Enter button, the phone has the arrow on the second row and points to the country Canada, instead of Australia.

6.3.3.5 Using the Menu and Receiving a Call

When you are accessing the menu, and the ZIP4x4 receives a call, the ZIP4x4 immediately changes the display to be as shown in section 6.3.2 on page 49. As soon as you end the call, the phone returns the display to be as it was prior to the call. You can then continue to use the menu functions.

6.3.3.6 Saving the Data

If you make a change to the data in the menu, then when you exit the menu system (or the phone waits for 60 s and exits the menu itself), the phone saves the data to non volatile memory. The phone displays the message:

Saving configuration

Please wait.

6. Interacting with the Phone

The process of saving the configuration takes about two seconds. Do not turn off the power while the phone is displaying this message.

When the phone has saved the data, the phone replaces the display shown above with either the idle message or a different message depending on the activity on the phone. You can make and receive a call while this message is being displayed. The phone continues the process of saving the data, and changes the display appropriately.

If you make a change to the configuration (from the menu) and turn off the power without exiting the menu system, the ZIP4x4 will not have saved your changes and the changes that you made will be lost.

6.4 Data Backup

When you remove power from the phone (or there is a power failure), the phone saves data in non-volatile memory. This storage does not depend on a battery and the data will therefore be saved for many years.

The data that is saved is:

• everything that you enter with the menu

• call forwarding and DND selection

• the list of recent calls made and received

• the list of 100 contacts in the phone book

Special Functions

7.1 Message

When you have voice mail messages, the LED on the Msg button flashes red for 500 ms and off for 500 ms. The LED can become lit while you are in the middle of a conversation, if someone has left you a voice mail while you are using the phone.

To retrieve your voice mail, press the button. If you did not have the phone off hook, the phone uses speaker mode and dials the number.

The operation of the voice mail system is independant of the operation of the phone. Follow the prompts for the voice mail system to listen to and delete your messages.

7.2 Encryption

7.2.1 Description

The speech traffic to and from an IP phone is sent over the LAN. It is possible for a person who is equipped with the appropriate equipment to monitor the LAN traffic and thus hear your conversation. If you want to keep your conversation private so that it cannot be monitored, you should enable encryption on the phone.

The administrator can select whether encryption is normally on, normally off, always on, or never on:

• If the phone is configured so that encryption is always on, pressing the Encrypt button has no

effect. Your phone can make calls only to devices that also support encryption. Your phone cannot make a call to, or receive a call from, a device that cannot encrypt the speech. You cannot turn off encryption during a call.

• If the phone is configured so that you have control over the encryption (normally on or

normally off), your phone can communicate with devices that support or do not support encryption. You can use the Encrypt button to engage or stop encryption. If you make a call

1. The phone dials the address (name or number) stored at memory location 00, for the voice mail server. This address can be filled from the configuration file or by using the menu. See section 5.2 on page 36 for details of the configuration file. See section 9.6.5 on page 141 for details how to enter the phone number of the voice mail system through the menu.

2. See section 9.6.6 on page 143 for details.

ZIP4x4 User’s Manual

to a device that does not support encryption, and you have requested that the call be encrypted or your phone by default is trying to engage encryption, the call will complete with encryption disabled. You can engage and stop encryption during a call.

The phone tries to establish all calls to be encrypted if configured for normally on. You can turn off encryption before or during the call.

The phone tries to establish all calls to be without encryption if configured for normally off. You can turn on encryption before or during the call.

• If the phone is configured so that encryption is never on (cannot be engaged), pressing the

Encrypt button has no effect. Your phone can make calls only to devices that are do not require encryption. Your phone cannot make a call to, or receive a call from, a device that always encrypts the speech. During a call, your phone will reject a request by the far end to engage encryption.

Regardless of the setting chosen by the administrator, the LED on the Encrypt button is off when the phone is idle. It becomes active only during a call as described in the sections below.

ZIP4x4 encryption is based on open standards. To encrypt the conversation, each person must be using a device that supports these open standards, such as another ZIP4x4 or compatible phone.

The encryption is completely loss-less. That is, the quality of the voice is the same whether the voice is encrypted or not. The encryption introduces negligible delay to the speech. When you switch between the call being encrypted or not encrypted, the ZIP 4x4 performs this almost instantaneously, but can take as long as 200 ms if there is a lot of traffic on the network.

Ensure that you understand the various ways to originate and terminate a call as described in section 8.2 on page 72 and section 8.6 on page 94 before reading the remainder of this section. If you want to create a conference call with encryption, ensure you know how to use the conference functions as described in section 8.8 on page 99.

7.2.2 Individual Calls

7.2.2.1 Making a Call When Encryption is Always On

Whenever you select a call appearance (directly or indirectly) to make a call, the LED on the Encrypt button flashes green synchronously with the green LED on the call appearance button.

If the device that you are calling supports encryption, the call completes as normal and the ZIP4x4 lights the LED on the Encrypt button continuously green.

If the device that you are calling cannot support encryption, the call will not complete. Your ZIP4x4 plays the fast busy tone (congestion tone) and flashes the LED on the call appearance button and the Encrypt button green and red for 250 ms each color. The display changes to:

1. Encrypt Rejected 4083280450

The phone shows the call appearance number and the name, number, or address of the person you were trying to call.

The phone maintains this state until you go on hook.

7.2.2.2 Receiving a Call When Encryption is Always On or Never On

If your ZIP4x4 is configured so that encryption is always on and it receives a call from a device that has encryption always on, or if your ZIP4x4 is configured so that encryption is always off and it receives a call from a device that has encryption always off, your phone will answer the call. The phone turns on the LED on the Encrypt button if encryption is engaged.

If your ZIP4x4 is configured so that encryption is always on and it receives a call from a device that has encryption always off, or if your ZIP4x4 is configured so that encryption is always off and it receives a call from a device that has encryption always on, your phone will reject the call. The phone does not make any sound or light any LEDs. Your phone accumulates this as a missed call (see section 8.4.4.3 on page 88). You can identify that the call was rejected as described in section 8.7.5 on page 98.

7.2.2.3 Making a Call With Encryption Normally On or Normally Off

When you enable encryption on the phone, it functions on each line independently. Therefore you can have an encrypted call with a person on one call appearance and a call that is not encrypted with another person on a different call appearance.

To encrypt a call prior to dialling:

• If the phone is configured so that encryption is normally off, press a free call appearance

button then press the encrypt button.

7. Special Functions

• If the phone is configured so that encryption is normally on, as soon as you start to make a call

the phone enables encryption.

The phone flashes the LED on the call appearance button green and also flashes the LED on the Encrypt button synchronously. Dial the number using any of the methods that you can use for a call that is not encrypted.

To encrypt a call that is already established, press the Encrypt button during the conversation.

If the other person’s phone can accept encrypted voice the ZIP4x4 lights the LED on the Encrypt button solid green but makes no change to the display.

If the far end phone rejects the request to enable encryption, your ZIP 4x4 beeps three times through the audio channel you are using, and displays:

Warning: Encryption turned off by far end.

The phone holds this display for two seconds, until you press a key, or go on hook.

7.2.2.4 Answering a Call With Encryption Normally On or Normally Off

Your phone automatically configures itself to engage or not engage encryption depending on the request from the calling device. Your phone makes no sound and makes no change to the LCD. It lights the LED on the Encrypt button continuously green if encryption is engaged.

ZIP4x4 User’s Manual

7.2.2.5 When the Other Party Turns on Encryption During a Call

If your phone has been configured to allow encryption, the phone immediately accepts the encryption request and lights the LED on the Encrypt button continuously. The speech is now secure. Your phone makes no sound and makes no change to the LCD.

7.2.2.6 When You Select to Turn Off Encryption

To turn off encryption on a call prior to dialling:

• If the phone is configured so that encryption is normally off, the phone does not attempt to

encrypt the call when you initiate it.

• If the phone is configured so that encryption is normally on, press a free call appearance

button then press the encrypt button.

If you turn off the encryption during a call, your phone turns off the LED on the Encrypt button. The speech is no longer encrypted and therefore not secure.

If you try to turn off encryption and the other person is using a device that can accept only encrypted speech, the other device will reject the request and your phone flashes the LED on the encrypt button for two seconds (250 ms on and 250 ms off). The speech will remain encrypted and thereafter the LED on the Encrypt button remains lit continuously.

7.2.2.7 When the Other Party Selects to Turn Off Encryption

If the person with whom you are talking turns off the encryption, your phone beeps three times through the audio channel that you are using, turns off the LED on the Encrypt button, and displays:

Warning: Encryption turned off by far end.

The phone holds this display for two seconds, until you press a key, or go on hook.

7.2.3 Holding, Parking, Transferring, and Forwarding Calls

When you put a call on hold or park it, the other person’s device now communicates with the call manager system, whereas it previously communicated with your phone. Similarly, when you transfer a call or forward a call, the other person’s device now communicates with someone else’s phone.

In each of these cases the encryption policies of the devices have to be compatible or the call may be dropped.

For example, consider the case when you are speaking with a person who puts the call on hold:

• If your phone is configured for normally on or normally off, it will adapt to the new speech

path coming from the phone system by either engaging or turning off encryption.

• If your phone is configured for always on or never on, the phone system must support

encryption in the former case or must be able to establish communication without encryption in the latter case. If the phone system cannot communicate with your phone, your phone rejects the call and your conversation is not placed on hold. Depending on the phone system your call may then be dropped or the phone system may reconnect you to the other person.

If you put a call on hold successfully, the phone turns off the LED on the Encrypt button. If the phone system rejects the call and does not return the call to your phone, the call will be dropped and the ZIP4x4 will turn off the LED on the respective call appearance button.

As another example, consider the case when you transfer a call or you have set call forwarding rules so that calls are automatically routed to another destination. The policies of the devices used by the original caller and the final called party must match or the call may be dropped.

7.2.4 Conference Calls

7.2.4.1 General

All calls that comprise a conference call must be encrypted or not encrypted. You cannot mix calls on a conference call that are encrypted or not encrypted because this makes the entire conference subject to eavesdropping and is therefore not secure.

7. Special Functions

After you have set up the call with the first person, all subsequent calls added to the conference must be encrypted or not encrypted depending on whether the first call has encryption engaged or not. You can join other parties to the conference in the same way that you can you can join parties for a conference that is not encrypted and as described in section 8.8.5 on page 101.

7.2.4.2 Adding Other Parties to an Encrypted Conference Call

If you have established an encrypted call, you cannot add other calls to the conference that are not encrypted:

• If you place the conference on hold and make a call to another person, pressing the conference

button will have no effect and you cannot join the person to the call if that new call is not encrypted.

• If you press the Conf key to select a new call appearance and then you call another party that

will not support the request for encryption, your ZIP4x4 drops the call if it was not rejected by the other party and shows:

3. Encrypt Rejected Technical.Support

The phone shows the call appearance number and the name, number, or address of the person you were trying to call. The phone holds this display for two seconds then reverts to the previous display.

• If you have one or more incoming calls and you press the Conf key to join those calls to the

conference, your ZIP4x4 joins only those parties to the call that are encrypted. The phone continues to alert you that you for the call or calls that could not join the conference. You need to place the conference on hold to answer the other call or calls.

ZIP4x4 User’s Manual

7.2.4.3 Turning Off Encryption on a Conference Call

The other parties to a conference call cannot turn off encryption on the conference call. Your ZIP4x4 will reject such a request. You can turn off encryption if all the devices that are participating in the conference have the encryption policy set to allow this.

If you try to turn off encryption and one or more devices can accept only encrypted speech, the other device will reject the request and your phone flashes the LED on the encrypt button for two seconds (250 ms on and 250 ms off). The speech will remain encrypted and thereafter the LED on the Encrypt button remains lit continuously.

7.3 User

7.3.5 Agents Operating Without a PC

Agents can function as part of an ACD group by using the ZIP4x4 phone. The phone automatically supports the following presence states:

• logged out

• available

• active

When an agent wishes to take a break, he or she should log out of the ACD group and log back in when available again. The phone does not support wrap up, so a new call can be presented to the agent immediately after the end of a previous call.

7.3.6 Log Out of ACD or Operator Group

When you move away from a phone that you have logged into as an operator or agent, you should log out so that your calls are no longer sent to that phone. If you forget to log out, the phone’s owner can log you out because you do not need a password to log out.

the phone displays the number of calls that you have missed, for example:

Sales support 17 missed calls Sun 31 Aug 02 20:31

7.5 Forward

7.5.1 Description

When the phone forwards a call, it redirects an incoming call to another destination (name or number). The destination can be another extension within the enterprise or an external number. You can turn on and off forwarding to instruct the phone to forward calls:

• unconditionally (all calls)

• if you do not answer the phone (on no answer)

• if you have an active call (when busy)

7.5.2 Unconditional

If you have configured the phone to forward calls unconditionally the phone does not announce that it is receiving an incoming call. It does not change the display or any LED. The phone immediately forwards the call to the destination that you have specified.

When the phone receives an incoming call, it does not accumulate this as a missed call.

7.5.3 On No Answer

If you have configured the phone to forward calls on no answer, the phone announces an incoming call in the usual manner. If you do not answer the call within ten seconds, the phone transfers the call to the destination that you have specified.

1. See section 6.3.1 on page 48 for a definition of the idle state.

The phone counts the number of calls that it forwards on no answer as missed calls.

7.5.4 When Busy

If you have configured the phone to forward calls when busy, the phone announces an incoming call in the usual manner if you do not have an active call.

If you have an active call, the phone forwards the call to the destination that you have specified. In this case, an active call is one where you are in the middle of a conversation or when you have put a conversation on hold. That is, the phone has a call button whose LED is lit continuously green or orange, or flashing green or orange.

If the phone receives more than one incoming call, the phone will indicate there are incoming calls on multiple call appearances. As soon as you answer one of the calls, the phone is now busy and it immediately forwards the other calls to the destination that you have specified.

The phone counts the number of calls that it forwards when busy as missed calls.

7.5.5 Configuring

Press the Forward button.1 The display changes to:

7. Special Functions

After you enter a name or number and press the Enter button, the phone lights the LED on the Fwd button continuously green. If you select off, the LED is turned off.

7.6 Park

The functionality of call park and call pickup are dependent on the phone system. You can park individual calls and conference calls. The following description is based on connecting your ZIP4x4 to a phone system that fully supports the park and pickup function.

7.6.1 Individual Call

To park a call, ensure you are in active communication with the person. That is, the LED on the call appearance button is lit continuously green. Press the Park button. The ZIP4x4 transfers the call to the park server and appears to the other person as if the call has been placed on hold. person with whom you were talking hears music on hold supplied by the phone system.

The system issues you a two digit number and the screen changes to:

Park on 37 Lancelot Capability Brown

The

You must note the two digit number that the system issues to you (in the example above it is 37). The display remains unchanged until another action takes place.

The phone transfers control of the call to the phone system, turns off the LED on the call appearance button, turns the LED on the Park button continuously red, and sounds an audible double beep in the earpiece or speaker. You can place the phone on hook.

The phone continues to display the screen shown above, and continues to light the LED on the Park button, until you go on hook, press a call appearance button, or use another function or feature of the phone. If the phone receives an incoming call, it will retain the display for a minimum of two seconds.

The phone does not provide dial tone until you go on hook and off hook again or you press a call appearance button.

To retrieve the call use the Pickup function as described in section 7.7 on page 66.

1. See section 8.7.3 on page 96 and section 8.7.4 on page 97 for a description of how to specify a memory location.

2. See section 9.6.5 on page 141 for details how to configure the address of the park server.

3. See section 8.5.2 on page 89 for a description of the hold function.

7.6.2 Failure to Park an Individual Call

If the park is unsuccessful, the phone displays:

* Failure to park * Lancelot Capability Brown

The phone retains this display until you press a key, lift the handset, or replace the handset, after which it displays the screen that the phone was showing prior to you attempting to park the call. You remain connected to the other person.

You can try to park the call again, but if your attempts to park a call fail repeatedly, you should consult your system administrator.

7.6.3 Conference Call

When you park a conference call, the ZIP4x4 parks each of the calls that comprise the conference call sequentially. The phone system returns a two digit park number for each of the calls in your conference call. For example, if you had three parties in a conference call, the phone displays:

7. Special Functions

Park on 57 58 59 Conference call

The phone system normally issues sequential numbers for the park numbers, but this cannot be guaranteed.

When you park the conference call, the parties to the call hear music on hold and cannot communicate with one another until you pickup the call as described in section 7.7 on page 66.

7.6.4 Failure to Park a Conference Call

If the park is unsuccessful, the phone displays XX instead of a park number:

Park on 57 XX 58 Conference call * Failure to park *

You can try to park the call again, but if your attempts to park a call fail repeatedly, you should consult your system administrator.

1. This is different from placing the conference on hold as described in section 8.8.2 on page 100.

ZIP4x4 User’s Manual

7.7 Pickup

The functionality of call park and call pickup are dependent on the phone system. You can pickup an individual call or a conference call that has been parked with the Park function as described in section 7.6 on page 64.

You can pickup a call that you parked yourself or that another person parked. You cannot pickup a call that was parked if the other party terminated the call while the call was parked.

7.7.1 Individual Call

You can resume a conversation that has been previously put on hold with the Park function using any ZIP4x4 phone. Press the Pickup button. The phone lights the LED continuously red on the Park button and displays:

Enter the two digit number for the parked call and press the Enter button or the # key. If you specify an invalid number (or if the party who was parked terminated the call in the mean time), the phone displays:

Pickup from }

If the phone is off hook, the phone will play the fast busy tone when you have entered an invalid number. You can enter a valid number or press the Esc button to exit the function.

Once the phone is connected to the parked call, the phone turns off the LED on the Pickup button and changes the display to the usual display of a call being connected, as described in section 8.3.5 on page 82.

If you forget the two digit number, call the operator for assistance. The operator may be able to assist you to find the number.

If you pickup a parked call that you had not intended to pickup, park the call again. Call the operator and tell the operator what has happened.

7.7.2 Conference Call

To pickup a conference call, you must pickup each of the calls that was parked. Therefore, you use the pickup function more than once to resume the conference.

1. Press the Pickup button.

The phone lights the LED continuously red on the Park button and displays:

Pickup from }37 (36 is invalid)

Pickup from }

2. Enter the two digit number for one of the parked calls and press the Enter button or the # key.

You are now communicating with one of the people on the conference call.

3. Press the Conf key.

The phone lights the first call appearance orange and selects a second call appearance.

4. Repeat from item 1 until you have picked up all members of the conference call.

If you try to pickup from an invalid number, the phone display indicates the error shown in the previous section.

7.8 Page

A page is an announcement sent to multiple people without those people needing to answer the phone. The phone plays the announcement through its speaker and you do not need to take the phone off hook to hear the announcement. If you have an active conversation (the LED on a call appearance button is lit continuously green or orange), the phone may or may not play the announcement depending on the settings chosen by the system administrator. The functionality of paging is dependent on the phone system.

To make a paging announcement, do the following:

7. Special Functions

1. If you have any active calls, put them on hold or terminate them.

2. If you have calls in progress on all four call appearances, you cannot page. Terminate at least

one of the calls to make a call appearance available.

3. Either:

a. Go off hook and press the Page button; or

b. Press the Page button.

4. The ZIP4x4 accesses the phone system and changes the display to:

Using the Phone

8.1 Going Off Hook and On Hook

You can use the handset, headset, or speaker for any call and easily switch between them – even during the same call. Subsequent sections detail the processes for making and terminating a call. This section briefly describes how to select between the three audio paths.

8.1.1 Using the Handset, Headset, and Speaker

To use the handset, pick it up. When you have finished using it, replace it in the cradle.

To use the headset, press the Hook button. When you have finished using it, press the Hook button again. When the headset is active, the phone lights the LED on the Hook button continuously red. When the headset is inactive, the phone turns off the LED.

To use the speaker, press and release the Speaker key. When you have finished using it, press the key again. When the speaker is active, the phone lights the LED on the Speaker key continuously red. When the speaker is inactive, the phone turns off the LED.

8.1.2 Off Hook

The term off hook means that you do one of the following:

• pick up the handset

• press the Hook button so that it is active (LED is lit continuously red)

• press the Speaker key so that the speaker is active (LED is lit continuously red)

The phone is said to be off hook when you have done any one of these things.

8.1.3 On Hook

The term on hook means that you do all of the following:

• replace the handset in the cradle

• press the Hook button so that it is inactive (LED is off)

• press the Speaker key so that the speaker is inactive (LED is off)

The phone is said to be on hook when all of these conditions are met.

ZIP4x4 User’s Manual

8.1.4 Switching Between the Handset, Headset, and Speaker

If you are using the handset and want to:

• use the headset, press the Hook button and replace the handset in the cradle

• use the speaker, press the speaker key and replace the handset in the cradle

If you are using the headset and want to:

• use the handset, pick up the handset

• use the speaker, press the speaker key

If you are using the speaker and want to:

• use the handset, pick up the handset

• use the headset, press the Hook button

8.1.5 Disconnecting the Handset or Headset

8.1.5.1 Handset

The phone cannot detect whether a handset is connected or not. Therefore if you connect or disconnect a handset during a call, the phone does not change its state.

8.1.5.2 Headset

Before a Call. If you connect a headset to the headset jack before making a call, you can use it to make or receive subsequent calls.

During a Call. If you are using a headset and unplug it during a call, the phone continues to send the sound to the headset jack. You cannot hear the other person and he or she cannot hear you. To resume the conversation, plug the headset back into the plug, lift the handset, or press the Speaker button.

If you connect a headset to the headset jack during a call, and the Hook button was inactive, then when you subsequently press the Hook button you can use the headset. If the Hook button was active when you inserted the headset you cannot use it during the current call.

8.2 Making a Call

To make a call, you normally want the phone to be in the idle state (see section 6.3.1 on page 48). You can obtain dial tone before you dial, or you can make a call without hearing a dial tone.

Section 8.2.1 on page 73 and section 8.2.2 on page 74 describe how to dial a number. You can also make a call by dialling a SIP address as described in section 8.2.6 on page 76.

You can make a call by dialling from memory (the phone book) as described in section 8.7.5 on page 98, or by dialling from the list of recent calls as described in section 8.7.5 on page 98.

1. It is not necessary to receive a dial tone. If the phone is connected to the switch, you can make a call. This is similar to the way you use a PC. If it is connected to the network, you can access the network – you do not require any audible feedback prior to accessing the network.

You can directly call from one ZIP4x4 to another without the aid of a call control system, as described in section 8.2.9 on page 79

Important This type of phone is different from phones that have been in common use for

the past 100 years. On those older phones, as you press a button to dial a digit, the phone transmits the digit to the telephone exchange. On the ZIP4x4, the phone sends all the digits as a complete message and you therefore need to inform the phone when you have entered all the digits. The phone then assembles the complete message and sends it to the SIP server.

8.2.1 Dialling a Number After You Get Dial Tone

1. Do one of the following:

a. Take the phone off hook.

• If all four call appearances are in use, nothing happens.

• If there is a free call appearance, the phone selects the lowest numbered call

appearance that is free. The phone flashes the LED on that call appearance button green for 250 ms and off for 750 ms. reserved but is not yet in use.

This indicates the call appearance has been

• The phone provides dial tone to the handset, headset, or speaker as appropriate.

8. Using the Phone

b. Press one of the call appearance buttons that has its LED turned off.

• The phone reserves the call appearance and indicates this by flashing the LED on that

call appearance button green for 250 ms and off for 750 ms.

• The phone selects speaker mode and provides dial tone to the speaker.

2. The phone shows:

1. Call

•

The number on the first row is the call appearance that has been reserved for this call.

3. Enter the digits.

• As you enter the digits, the phone displays the digits, for example:

1. Call 40883280

1. See section 8.1.2 on page 71 for a definition of off hook.

2. A summary of the meanings of the LEDs for the call appearance buttons is given in appendix B on page 157.

3. The tone that you hear is generated by the phone. You select that to match the tone commonly in use in your country. Section 9.5.7 on page 127 describes how you select the country where you live.

4. At this point, you can dial from a memory location in the phone book. When you do so, you don’t need to enter any digits or do any of the items listed in step 4. See section 8.7.3 on page 96 for details.

ZIP4x4 User’s Manual

digits.

1. Calling 4083280450

The first line of the display shows the call appearance that is being used for the call.

8. The phone indicates the call appearance that is being used by changing the flashing for the LED on the call appearance button. The LED will be lit for 750 ms and flash off for 250 ms.

9. While the call is proceeding, the phone plays ringback tone. This may be generated by the phone according to the country selection that you have made.

10. When the call is established (the called party has answered) the phone lights the LED on the call appearance button green continuously.

8.2.2 Dialling a Number without Dial Tone

You can make a call without having to hear a dial tone or the digits being dialled. You can do this while the phone is in the calculator mode. This mode is called “hot key dialling”.

1. Enter the digits. The phone shows the digits on the screen. As you enter the digits the phone does not play the DTMF sounds for the digits.

2. Do one of the following:

a. Pick up the handset. The phone selects the lowest number call appearance that is

available and sends the digits.

b. Press the Hook button. The phone selects the lowest number call appearance that is

available, sends the digits, and routes the sound to the headset.

c. Press the Speaker key. The phone selects the lowest number call appearance that is

available, sends the digits, and puts the phone into speaker mode.

1. If you want to send a # digit as part of the dialled name or number, see section 8.2.3 on page 75.

2. If you press any other call appearance button, the phone will clear the display and assume you want to make a new call.

d. Press one of the call appearance buttons. The phone sends the digits and puts the phone

into speaker mode.

e. Press the # key. The phone selects the lowest numbered call appearance that is available,

sends the digits, and puts the phone into speaker mode. The phone does not play the DTMF digit for the # key.

You can also dial directly from the phone book without a dial tone as described in section 8.7.3 on page 96.

8.2.3 Sending a # as Part of the Number

When you are entering a number and you press the # key the phone interprets that as the end of the number and sends the number to the switch without the #. If you need to send a # as part of the string, press the Func key. The phone changes the top row of the display to show:

1. Call Func:abc

The keys now allow you to enter letters as well as numbers. This is more fully described in section

8.2.6 on page 76. Press the * key twice to display characters that you can select. Use the right arrow

on the volume key to highlight the # character, then press the * key again. Finally, press the Func key so that the keys enter only numbers again.

8. Using the Phone

8.2.4 Dialling When in Calculator Mode

You can keep the phone normally in calculator mode as described in section 8.9.9 on page 105 and still be able to make and receive calls. When you want to make a call, you can do so with or without a dial tone.

If you want to dial a SIP address, you must exit calculator mode first.

1. Do one of the following:

a. Lift the handset or press the Hook button.

b. Press one of the call appearance buttons that is not lit.

2. The phone exits calculator mode, reserves a call appearance, and provides dial tone.

3. Dial the number or address as described in section 8.2.1 on page 73.

When you terminate the call, the phone returns to calculator mode if there is no activity on any of the call appearances (all LEDs on these buttons are off). When the phone resumes the calculator mode, the phone displays the state of any calculation that you had started.

8.2.5 Making a Call While Accessing the Menu

If you are accessing the menu and want to make a call, you can do so only by getting dial tone first. That is, you must go off hook or select a free call appearance as described in section 8.2.1 on page 73. When the call terminates the phone resumes access to the menu exactly as it was prior to the call. The phone automatically exits the menu function 60 s after the end of the call if you do not press any keys or buttons.

ZIP4x4 User’s Manual

If you are accessing the phone book, and have used the search function to locate a name, number, or address, then when you go off hook or select a call appearance, the phone calls that contact and exits the menu function.

8.2.6 Dialling Using a SIP Address

8.2.6.1 Purpose

When you dial using a SIP address, you don’t need to know a person’s phone number. This is a good method of making a call if the person’s address has been created logically. You can use any of the schemes described in section 8.2.1 on page 73 or section 8.2.2 on page 74. If the phone is in calculator mode see section 8.2.4 on page 75 for how to make the call.

A SIP address is normally written as:

SIP:name@domain

For example:

SIP:john.doe@zultys.com

With the ZIP4x4, you must not write “SIP:” because the phone will automatically insert that for you. Also, when you call an address that is within the same domain as your phone, you do not need to enter the domain name.

8.2.6.2 Entering an Address

To dial using a SIP address, you must take the phone out of calculator mode. See section 8.9.8 on page 105 for details. It is easier to enter an address in this manner without first selecting a call appearance or obtaining dial tone. When you have selected a call appearance, the phone times out between you entering characters and sends the characters. This time-out might be too short when creating an alphanumeric address.

To enter an alphanumeric address instead of a numeric address, press the Func key once. The display shows Func:abc on the top row. The function key in this mode locks the use of the keys so that you do not need to repeatedly press the Func key.

The digit keys 2 to 9 allow you to type the letters of the alphabet that are displayed on those keys. When you press a key, it selects the first character. If you quickly press the key again, it selects the second letter and so on. When you repeatedly press the key, the phone selects the next character in sequence, then the number of the key, then it scrolls back to the first letter.

To scroll through the list of characters, press the key within 800 ms of the last press. If you take longer than this, the cursor position moves to the right and when you next press the key you will select the first letter in the list. If you want to select a character from the same key to be the next character you enter, you can wait or you can press the right arrow on the volume key.

To select upper case characters instead of lower case characters, press the # key. The display shows Func:ABC on the top row. To return to selecting lower case characters, press the # key again. The arrow on that key reminds you the key is used to shift between upper and lower case characters.

The maximum length of a SIP address is defined to be 256 characters. However, the ZIP4x4 will allow you only to enter 64 characters. Once you reach that limit, the phone will not accept more characters.

8.2.6.3 Character Mapping on Numeric Keys

This is a list of the characters selected by repeatedly pressing the various keys:

1. ~, -, _, !, 1

2. a, b, c, 2; or A, B, C, 2

3. d, e, f, 3; or D, E, F, 3

4. g, h, i, 4; or G, H, I, 4

5. j, k, l, 5; or J, K, L, 5

6. m, n, o, 6; or M, N, O, 6

7. p, q, r, s, 7; or P, Q, R, S, 7

8. t, u, v, 8; or T, U, V, 8

9. w, x, y, z, 9; or W, X, Y, Z, 9

0. @, space, 0

*. * then selection

8.2.6.4 Using the * Key

When you press the * key, the ZIP4x4 selects the * which can be sent as a part of a dialled number, either by SIP or as a DTMF digit. If you press the * key twice within 800 ms, you can select from many different symbols. The phone changes the display to:

8. Using the Phone

Select character: .,:;-_#*()'"@&%/\<>~ +÷=±µ°?!§$€¥

The cursor is at the dot character. Use the left and right arrows on the volume key or the Up and Down buttons to move the cursor. Press the Esc button to exit this mode. When the cursor is highlighting the character you want to select press any other key. The phone places the character you selected in place of the * that it originally displayed.

You can enter a dot (period or full stop) quickly by pressing the * key three times.

8.2.6.5 Exiting Alphanumeric mode

You can put the phone out of the alphanumeric mode by pressing Func at any time. This will allow you to easily enter digits that may be part of the address. You can return the phone to alphanumeric mode by pressing the Func key again.

1. You cannot use some of these characters as part of an address. The SIP address is formulated based on the same rules as an email address.

ZIP4x4 User’s Manual

8.2.6.6 Display

The process for making a call to a SIP address, and what the LCD shows during the process, are similar to that described in section 8.2.1 on page 73 and section 8.2.2 on page 74 for dialling a number. When you are entering the address, the display shows:

8.2.6.7 Editing the Address

Use the volume key as described in section 8.2.7 on page 78.

8.2.6.8 Sending the Address

To send the address (and initiate the call), lift the handset, press the hook button, press the speaker key, or press a call button. If you did one of these prior to entering the address, press the # key twice or wait three seconds.

Call: Func:abc john.doe@z•

8.2.6.9 LEDs

The LEDs operate as they do when you enter a numeric phone number.

8.2.7 Editing a Number

You can edit a number or SIP address that you have entered by using the volume keys.

When you press the right arrow, the cursor moves forward through the digits. If the cursor was at the last digit, the phone places the cursor at the first digit.

When you press the left arrow, the phone deletes the character to the left of the cursor. the left arrow when the cursor is at the first character, the phone moves the cursor to the position after the last character (and it therefore does not delete any character).

For example, suppose you want to dial the number 12345, but instead you enter:

You can either press the left arrow twice, to get:

Then enter 345. Or, press the right arrow three times so that the cursor is at the 4. Then enter 3. The digit three is inserted before the digit 4.

1245

If you press

1. This is equivalent to the backspace action on a computer’s keyboard.

8.2.8 Dialling an Invalid Destination

When you initiate the call, the phone performs a simple check on the number or address that you entered. If this is invalid, the phone displays:

1. Invalid address 408€32

The phone retains this display for three seconds before returning to whatever was displayed prior to your initiating the call (usually the idle display). If you had selected a call appearance, it will become idle after five seconds.

8.2.9 Making a Call Without a SIP Proxy

The ZIP4x4 is intended for use with a telephone system but it is possible to use it without one. You might do this if you have two phones either directly connected or isolated on a network. To make the call, you must know the IP address of the phone you want to call or the other device must have an FQDN that your ZIP4x4 can resolve with a DNS server.

To make a call directly to the other device, ensure that:

8. Using the Phone

• your phone has a unique IP address

• your phone has not registered with a SIP registrar

• you know the IP address and device ID of the phone you want to contact

The following instructions contain many steps, some of which may not be applicable, depending on the configuration of the phone prior to your using it:

1. Log into the phone using the password as described in section 9.6.1 on page 132.

2. Disable DHCP, set a static IP address, subnet mask and default gateway, as described in

section 9.6.2 on page 133.

3. Remove the address of the TFTP server and the address of the SIP outbound proxy, as described in section 9.6.2 on page 133.

4. Assign a unique device ID to the phone and remove the domain name as described in section

9.6.5 on page 141.

5. Repeat these steps for the other phone.

6. Connect the phones so that they can be accessed over the LAN.

7. Create a call from one phone to the other using the method outlined in section 8.2.6 on page

76, but address the other phone by its device ID and IP address:

1. Call Func:abc <device ID>@<IP address>

1. It is not a requirement that the phones have a static IP address. However, if you use DHCP, the phone may receive a new IP address after its lease expires. You will have to find out this new IP address before you can make a call to that phone.

ZIP4x4 User’s Manual

For example, if the two phones have device IDs of East and West, you might make a call from East to West by typing:

1. Call Func:abc West@10.1.13.17

If the other phone has an FQDN, you might enter:

1. Call Func:abc West@Zultys.West.com

8. If you want to repeatedly make calls in this manner, enter the address into a memory location, as described in section 9.2.2 on page 109. Dial the number from memory as described in section 8.7.3 on page 96.

8.3 Call Proceeding and Call Answered

8.3.1 Calling

When you have started to make a call, the display changes to:

The display shows the call appearance that is in use for this call and the number or address being called. The display indicates the time (minutes and seconds) since you started the call and reflects the time that you have been waiting for the call to connect.

The phone displays the called number on the second line. In the unlikely event that the number is greater than 20 digits, the ZIP4x4 displays the rest of the number on the third line.

If the number that you have dialled is in your phone book, the ZIP4x4 displays the name of the called party instead of the phone number. It will display the name on the second and third lines. Where possible, the ZIP4x4 will split the name at a space character. For example:

or:

1. Calling 4083280450

0:17

1. Calling Zultys Technologies

0:17

1. Calling Lancelot Capability Brown 0:17

The phone will continue to use this name instead of the number for future displays during this call.

If you have dialled the person using a SIP address, the phone will display this instead of a number. It will try to break the name at a period (full stop), “at” symbol, or other punctuation.

The LED on the call appearance button flashes green for 750 ms and off for 250 ms.

You will hear nothing during this phase of the call.

8.3.2 Ringback

8.3.2.1 ZIP4x4 to SIP Phone Calls or ZIP4x4 to ISDN Calls

When you make a call to another SIP phone, the ringback that you hear will be generated by your phone. The tones will be those that you have selected for the country.

If you are making a call to the PSTN, the SIP to PSTN gateway normally opens the communication path so that you hear the sound coming from the network. Therefore, if you are calling a different country you will hear the ringback tone from that country. This tone may be different from that used in your country.

8. Using the Phone

The LED on the call appearance button continues to flash green for 750 ms and off for 250 ms. The display changes to:

The timer continues to show the time since you initiated the call.

8.3.2.2 ZIP4x4 to CAS Calls

If you are connected to the PSTN using T1 CAS circuits, your SIP to PSTN gateway may not know the status of the connection. It may open the speech path even though there is no ringback. The LED on the call appearance button will then be lit solidly green.

The phone behaves as if the call has been established as described in section 8.5 on page 89. Because the speech path is open, you may hear busy tone although the phone indicates that you are connected.

ZIP4x4 User’s Manual

8.3.3 Far End Busy

If the person you are calling is busy, the phone either plays the busy tone for your country or the busy tone that is generated by the phone network at the far end. This depends whether your server has indication that the called party is busy or not. If your server is aware the called party is busy, your phone flashes the LED on the call appearance button green for 750 ms and red for 250 ms. The display changes to:

The phone stops the timer as soon as it receives notification that the called party is busy. The phone maintains this state until you go on hook.

8.3.4 Network Busy

If the network is busy, the phone either plays the fast busy tone (congestion tone) for your country or the fast busy tone that is generated by the phone network at the far end. This depends whether your server can detect whether or not the network is busy. If it is aware the network is busy, your phone flashes the LED on the call appearance button green and red for 250 ms each color.

1. Far end busy 4083280450

0:28

The ZIP4x4 displays this message if the number you are calling does not exist or is not available.

The display changes to:

The phone stops the timer as soon as it receives notification that the network is busy.

The phone maintains this state until you go on hook.

8.3.5 Call Answered

8.3.5.1 Expanded Display

When the called party answers, the phone makes the LED for the call appearance to be lit continuously green and changes the display to:

1. Network busy 4083280450

The phone truncates the number (or name) that you have called to 12 characters so that it can display the duration of the call. The phone leaves a minimum of two spaces between the end of the phone number and the timer.

The timer shows the call time in minutes and seconds until the call length has reached an hour. It then displays the time in hours and minutes.

The phone displays the current time and date just as it does in the idle state.

You can toggle the phone to the expanded display mode by pressing the Enter button.

8.3.6 Network Failure

If the phone sends a message to the SIP server that the SIP server does not answer, the phone displays:

The phone makes the handset, headset, and speaker quiet and displays the message until you attempt to make another call or perform another task on the phone.

You should contact the administrator of the system if you see this message.
