Introduction to the Linksys Voice System

Getting Started

This chapter introduces you to the Linksys Voice System (LVS) by describing the components and presenting several deployment scenarios.

• ”Introduction to the Linksys Voice System,” on page 13

• ”Deployment Scenarios,” on page 15

• ”Initial Installation, and Configuration,” on page 20

Introduction to the Linksys Voice System

The LVS is an affordable and feature-rich voice over IP (VoIP) telephone system that is designed especially for small businesses. The LVS uses standard TCP/IP protocols and can provide global connectivity through any Internet Telephony Service Provider (ITSP) that supports Session Initiation Protocol (SIP).

At minimum, the LVS includes a SPA9000 IP PBX and one or more SPA900 series IP phones. These devices are connected through a switch to a local area network. With an Internet connection, the LVS can subscribe to ITSP services to take advantage of low calling rates. With the optional SPA400, the LVS can connect to the Public Switched Telephone Network (PSTN) to support legacy phone lines.

Figure 1-1 illustrates the LVS Solution in a typical deployment.

Introduction to the Linksys Voice System

Getting Started

SPA9000 IP PBX

The SPA9000 is an IP PBX that supports up to 16 phones. It also has a built-in Analog Telephone Adapter (ATA) with two FXS ports for analog telephones, fax devices, or an external music source for the music on-hold service. Devices connected to the FXS ports are not included in the licence's device count.

The SPA9000 has four line interfaces, which can be configured in any combination for ITSP service, ISDN access, SPA400 PSTN access, or SPA400 voice mail service. A different ITSP account can be configured on each line interface. If a service provider supplies a group of sequential direct inward dial (DID) phone numbers (such as 408-555-0100 through 555-0145) the SPA9000 can support all of the assigned numbers on a single line interface.

The SPA9000 includes an Auto Attendant service that plays pre-recorded voice messages to offer the caller a menu of choices and to direct the call. When the Auto-Attendant is enabled, it parses and operates on user input (key presses that produce DTMF tones) following the rules specified in the Auto Attendant script on the SPA9000.

SPA400 SIP-PSTN Gateway and Voicemail Server

The SPA400 provides a SIP-PSTN gateway for voice connectivity between the PSTN and the local client stations that are connected to the SPA9000. It also includes an integrated voice mail application that supports up to 32 voice mail accounts with customized greetings, providing LVS users the ability to receive and playback voice mail messages.

Each SPA400 occupies one of the four line interfaces on the SPA9000. The SPA400 has four ports for that can be connected to PSTN or ISDN lines.

SPA900 Series IP Phones and Accessories

Linksys provides a variety of IP phones to meet the needs of small businesses.

Table 1-1

provides a comparison of the available models.

NOTE: This guide explains how to configure the SPA9000 and the SPA400 to support the calling features on the phones. For more information about the phones, see the Linksys Phone Administration Guide and the Linksys SPA9x2 Phone User Guide.

Access Levels

Basic Administration of the SPA9000

Access Levels

You can use the SPA9000 administration web server to configure and manage your system. Three levels of access are available:

• User Level: The User account only has the privilege to access part of the web profile

parameters.

• Administrator Level: The Administrator account has the privilege to modify all the web

profile parameters and can also modify the passwords of both Administrator and User account.

• Advanced: Administrators and Users can view advanced features by clicking the

Advanced link in the top right corner or lower left corner of the menu bar.

By default, no passwords are assigned for either the Administrator account or the User account. If the password has been set for the Administrator account, the browser prompts for authentication.

You can switch from User access to Administrator access by clicking the Admin Login link. Likewise, you can switch from Administrator access to User access by clicking the User Login link. If a password is set, you will be prompted to enter the password after you click the link.

Setting Passwords for User and Administrator Accounts

The Administrator account name for the SPA9000 is admin (with a lower-case a) and the User account name is user. These account names cannot be changed.

Note The system prompts for an Administrator account password only if a

password has been set. By default, there is no password. You should set a password to protect your SPA9000 from unauthorized access.

TIP: Before you make changes, it is recommended that you save a copy of your current working configuration:

1. In Internet Explorer, connect to the administration web server.

2. From the menu, choose File > Save As.

3. Save the configuration as Web Page Complete. You can use the saved file to review the saved settings in all pages of the administrative GUI.

NOTE: To save a Telephone Configuration, first enter the IP address for the configuration, and then follow the above procedure.

Configuring Daylight Saving Time

You can enter a daylight saving time rule to ensure that the time is adjusted appropriately for your region.

Syntax and Examples

SYNTAX:

start = <start-time>; end=<end-time>; save = <save-time>

EXAMPLE: start=3/9/7;end=11/2/7;save=1

In this example, Daylight Saving Time begins March 9, 2007, and ends Nov. 2, 2007. One hour is added to the time of day during this period.

• The <start-time> and <end-time> values specify the start and end dates and times of

daylight saving time. Each value is in the following format: <month> /<day> / <weekday>[/HH:[mm[:ss]]]

Linksys Voice System Administration Guide 28

Configuring Basic Settings

Basic Administration of the SPA9000

• The <save-time> value is the number of hours, minutes, and/or seconds to add to the

current time during daylight saving time. The <save-time> value can be preceded by a negative (-) sign if subtraction is desired instead of addition. The <save-time> value is in this format: [/[+|-]HH:[mm[:ss]]]

• The <month> value equals any value in the range 1-12 (January-December).

• The <day> value equals [+|-] any value in the range 1-31. If <day> is 1, it means the

<weekday> on or before the end of the month (in other words the last occurrence of <weekday> in that month).

• The <weekday> value equals any value in the range 1-7 (Monday-Sunday). It can also

equal 0. If the <weekday> value is 0, this means that the date to start or end daylight saving is exactly the date given. In that case, the <day> value must not be negative. If the <weekday> value is not 0 and the <day> value is positive, then daylight saving starts or ends on the <weekday> value on or after the date given. If the <weekday> value is not 0 and the <day> value is negative, then daylight saving starts or ends on the <weekday> value on or before the date given.

• The abbreviation HH stands for hours (0-23).

• The abbreviation mm stands for minutes (0-59).

• The abbreviation ss stands for seconds (0-59).

Entering the Daylight Saving Time Rule

1. Connect to the SPA9000 administration web server, and choose Admin access with Advanced settings. (See

”Connecting to the SPA9000 Administration Web Server,” on

SPA9000 Ethernet Port

The SPA9000 Ethernet port is used to connect an administrative computer. Typically, this port is used only during initial installation and configuration. With WAN access enabled by default, you can manage your SPA9000 from any computer that is connected to the same subnetwork as the SPA9000. The default IP address for this port is 192.168.0.1.

LAN and Application Guidelines

Although the SPA9000 can provide router and Application services, it does not have sufficient power to provide both phone and routing/application services in a highly utilized environment. For this reason, Linksys recommends that the SPA9000 not be used as a router at any time. Instead, use the SPA9000 as an appliance by connecting its INTERNET port to a network switch and leaving the ETHERNET port disconnected.

It is recommended that you leave the LAN and Application settings at the default values.

Linksys Voice System Administration Guide 29

Configuring Basic Settings

Configuring Multicast Addressing and Group Paging

For initialization and system updates, the SPA9000 communicates with all the client stations at once by using IP multicast. This method also is used in the group paging application. For this reason, the SPA9000 and the SPA9xx IP phones must reside on a network where multicasting is allowed. Default addresses are provided, but you can change these addresses as needed.

Note Make sure that the SPA9000 and the SPA900 Series phones use the same

multicast address and port number. Also make sure that you enable spanning tree and port fast on your LAN switch, as described in the LVS Installation and Configuration Guide.

Setting the Multicast Address

For administration purposes, the SPA9000 can send the following reboot, restart, page, and ring messages to the group:

•Graceful reboot

• Immediate reboot

•Graceful restart

• Immediate restart

•Group page start

•Group page end

• Get ringing calls

Setting the Group Page Address

In the group paging application, the originator sends RTP packets to an IP multicast address at which all the other client stations are listening. This address is chosen by the SPA9000 and is configured on the Voice > SIP page, PBX Parameters section, Group Page Address field.

The originator starts the group page by choosing PageGroup from the Corporate Directory on the phone, or by using a speed dial or personal directory entry. All client stations are alerted at once. If the client station is on a call when a group page starts, the call is automatically placed on hold. The speaker on each paged station is turned on automatically unless the handset or headset is being used. Group page is one-way only. The paged client stations can only listen to the call from the originator.

1. Connect to the SPA9000 administration web server, and choose Admin access with Advanced settings. (See

Collecting System Logs and Debug Information

If you are working with an ITSP that needs more information to configure interoperability, you can collect system logs and debug information for the SPA9000. You can send these logs to the ITSP for their use.

Requirements:

• You need a PC that is on the same subnetwork as the SPA9000, to capture the log files.

This PC needs to be running a syslog daemon. Enter the IP address of this PC on the Voice > System page, in the Syslog Server and Debug Server fields.

• If you are interested in working with these logs yourself, you will need to use an

application that reads syslogs. Linksys partners can download a syslog server tool (slogsrv.exe) from the Linksys Partner Connection. (VARs, see Product Utilities > Linksys Voice System > SPA Utilities > Syslog Server for SPA Devices. SPs, see Technical Tools > SPA Utilities > Syslog Server for SPA Devices.)

Note As a best practice, enable logging only when needed, and disable

logging when you finish the investigation. Logging information can impact system performance.

1. Connect to the SPA9000 administration web server, and choose Admin access with Advanced settings. (See

”Connecting to the SPA9000 Administration Web Server,” on

page 24

2. Click Voice tab > System.

system activity (no SIP messages).

• Debug Server: Enter the server IP address and port to collect information about SIP

messages.

NOTE: SIP logging is not enabled until you complete this procedure by enabling system logging on the line interface.

i. Debug Level: Choose 3 to enable debugging.

4. Click Voice tab > Line N, where N represents the line interface number of the line that you are investigating.

5. Scroll down to the SIP Settings section, and then choose a SIP Debug Option, based on the level of SIP information that you want to collect.

NOTE: Typically, your ITSP support personnel will tell you what type of information they need in the logs. The drop-down list includes three categories of options: none,1- line, and full.

•none: Disables SIP logging

• 1-line: Identifies the SIP message type but does not include the message body

Options within this category allow you to choose to exclude OPT, NTFY, and REG information to reduce the length of the logs.

• full: Includes the SIP message body

Options within this category allow you to choose to exclude OPT, NTFY, and REG information to reduce the length of the logs.

EXAMPLES:

• If you are troubleshooting a problem with line registration. Select full.

• If you are troubleshooting a call problem. Select full excl. OPT|NTFY|REG.

6. Click Submit All Changes. The information is stored on the specified server and port, with a file name in the following format: syslog.port.log.

7. IMPORTANT: When you finish collecting the information, disable the logging:

About LVS and SIP

Configuring the SPA9000 for ITSP Interoperability

This chapter provides configuration details for the purpose of helping you to ensure that your infrastructure properly supports the LVS.

•

”About LVS and SIP,” on page 39

• ”Network Address Translation (NAT) and Voice over IP (VoIP),” on page 40

• ”Firewalls and SIP,” on page 43

• ”Configuring SIP Timer Values,” on page 44

About LVS and SIP

The LVS is implemented using open standards, such as Session Initiation Protocol (SIP), to help ensure interoperation with all ITSPs that support SIP. This section provides information about the SIP requests and the settings that you may need to adjust on your network or your SPA9000 to help ensure interoperability.

The VoIP telephone service is coordinated by SIP requests and responses, whether the calls are internal or external.

Figure 3-1 illustrates the SIP requests and responses between client

stations in the LVS. The SPA9000 acts as a SIP proxy and establishes a session. After the session is established, Real Time Protocol (RTP) traffic flows directly between the two client stations.

Figure 3-1 SIP Requests and Responses for Internal Calls

Likewise, SIP requests and responses are exchanged to support outbound and inbound calls that are handled through the ITSP service. In

Figure 3-2, UserA and UserB are client stations that

are registered to the SPA9000. When UserA calls UserC, the SPA9000 directs the request to the SIP proxy at the ITSP, which is then responsible for routing the request to UserC. After the session is established, RTP is anchored by the SPA9000.

Network Address Translation (NAT) and Voice over IP (VoIP)

NAT is a function that allows multiple devices to share the same public, routable, IP address to establish connections over the Internet. NAT is present in many broadband access devices to translate public and private IP addresses. To enable VoIP to co-exist with NAT, some form of NAT traversal is required.

Some ITSPs provide NAT traversal, but some do not. If your ITSP does not provide NAT traversal, you have several options.

• ”NAT Mapping with Session Border Controller,” on page 41

• ”Configuring NAT Mapping with a Static IP Address,” on page 41

• ”Configuring NAT Mapping with STUN,” on page 42

NAT Mapping with SIP-ALG Router

You can achieve NAT mapping by using a router that has a SIP ALG (Application Layer Gateway). The Linksys WRV200 router is recommended for this purpose, although any router with a SIPALG can be used. By using a SIP-ALG router, you have more choices in selecting an ITSP.

NAT Mapping with Session Border Controller

It is strongly recommended that you choose an ITSP that supports NAT mapping through a Session Border Controller (see

Figure 3-3). With NAT mapping provided by the ITSP, you have

more choices in selecting a router.

Figure 3-3 NAT Support with Session Border Controller Provided by ITSP

Configuring NAT Mapping with a Static IP Address

Configuring NAT mapping in the SPA9000 is recommended only if the ITSP network does not provide a Session Border Controller functionality. In this case, and if the external (public) IP address is static, then it is recommended to perform a static (permanent) mapping on SPA9000. This setting is also recommended if NAT mechanism used in the router is symmetric.

Note The LAN switch needs to be configured to enable Spanning Tree

Protocol and Port Fast on the ports to which the SPA9000 and the SPA9xx phones are connected.

1. Connect to the SPA9000 administration web server, and choose Admin access with

Advanced settings. (See

”Connecting to the SPA9000 Administration Web Server,” on

page 24

2. Click Voice tab > SIP.

3. Scroll down to the NAT Support Parameters section, and then enter the following settings to

support static mapping to your public IP address:

• Handle VIA received, Insert VIA received, Substitute VIA Addr: yes

• Handle VIA rport, Insert VIA rport, Send Resp To Src Port: yes

• EXT IP: Enter the public IP address for your router.

Configuring NAT Mapping with STUN

Configuring NAT mapping in the SPA9000 is recommended only if the ITSP network does not provide a Session Border Controller functionality. In this case, and if the external (Public) IP address is assigned dynamically by the network (and the router uses asymmetric NAT mechanism), it is possible to use STUN as a mechanism to discover the NAT mapping in SPA9000. This is considered a practice of last resort and should be used only if the other methods are unavailable.

Note STUN is a viable option only if your router uses asymmetric NAT. See

Appendix A, "Advanced Topics in LVS Administration," ”Determining Whether the Router Uses Symmetric or Asymmetric NAT” section on page 136.

Firewalls and SIP

To enable SIP requests and responses to be exchanged with the SIP proxy at the ITSP, you must ensure that your firewall allows both SIP and RTP unimpeded access to the Internet.

• Make sure that the following ports are not blocked:

– SIP ports—UDP port 5060 through 5063, which are used for the SPA9000 line

interfaces

– RTP ports—16384 to 16482

• Also disable SPI (Stateful Packet Inspection) if this function exists on your firewall.

Configuring SIP Timer Values

Configuring the SPA9000 for ITSP Interoperability

Configuring SIP Timer Values

The SPA9000 is configured with default timer values that should be adequate in most circumstances. However, you can adjust the SIP timer values as needed to ensure interoperability with your ISTP. For example, if SIP requests are returned with an “invalid certificate” message, you may need to enter a longer SIP T1 retry value.

To view the default settings or to make changes, open the Voice > SIP page, and scroll down to the SIP Timer Values section. For field descriptions, see

Configuring Call Capacity for a Line Interface

Each line interface has a limited number of simultaneous calls that are allowed, based on the Call Capacity parameter. When the maximum call capacity is reached, the SPA9000 does not allocate any more calls to that line interface.

This section includes the following topics:

•

”Bandwidth Requirements and Call Capacity,” on page 51

• ”Setting the Call Capacity Parameter,” on page 52

Bandwidth Requirements and Call Capacity

The available connection bandwidth determines the maximum number of simultaneous calls that the system can support with the appropriate audio quality. Before installing and configuring the LVS components, use this information to determine the maximum number of simultaneous VoIP connections that the system can support. For asymmetric connections, such as ADSL, the maximum number of calls is determined by the upstream bandwidth. In general it is a good practice to use no more than 75% of the total available bandwidth for calls. This provides space for data traffic and helps ensure good voice quality.

Table 4-1 provides the approximate bandwidth budget for different codecs.

Configuring Dial Plans

Configuring Phone Lines and Calling Routing Behavior

How the Dialed Digits are Processed

When a user lifts a handset or presses a speaker button, the following sequence of events begins:

1. The phone begins collecting the dialed digits. The inter-digit timers starts tracking the time that elapses between digits. For more information, see

”Setting the Timers for the Dial Plan,”

on page 59

2. If the inter-digit timer value is reached, or if another terminating event occurs, the phone compares the dialed digits with the PHONE (SYSTEM) dial plan (on the SPA9xx Telephone Configuration > Ext N page, Dial Plan section). For more information, see

”Acceptance and

Transmission the Dialed Digits,” on page 56

, ”Editing the System Dial Plan,” on page 57, and

”Entering a Phone Dial Plan,” on page 58.

NOTE: If a call is placed from a phone that is connected to a SPA9000 FXS port, the FXS port dial plan applies.

See

”Configuring a Line Interface for a SPA400 (PSTN or Voice Mail),” on

page 48

3. If the phone dial plan allows the call to process, the dialed numbers are sent to the SPA9000.

4. The SPA9000 compares the dialed digits to the CALL ROUTING RULE (on the SPA9000 Voice > SIP page, PBX Parameters section). For more information, see

”Configuring a Call Routing

Rule,” on page 63

5. If the call routing rule allows the call to process, then the SPA9000 compares the dialed digits to the LINE INTERFACE dial plan (on the SPA9000 Voice > Line N page, Dial Plan section). For more information, see

”Entering the Line Interface Dial Plan,” on page 59.

6. The SPA9000 uses the information in the line dial plan to manipulate the number (for example, to remove steering digits) and then transmits the number.

Digit Sequences

A dial plan contains a series of digit sequences, separated by the | character. The entire collection of sequences is enclosed within parentheses. Each digit sequence within the dial plan consists of a series of elements, which are individually matched to the keys that the user presses. The sequence can include the elements that are listed in

Table 4-2.

Note White space is ignored, but may be used for readability.

Table 4-2 Digit Sequences and Functions

Digit Sequence Function

0 1 2 3 4 5 6 7 8 9 0 * #

Enter any of these characters to represent a key that the user must press on the phone keypad.

Enter x to represent any character on the phone keypad.

Linksys Voice System Administration Guide 54

Configuring Dial Plans

Configuring Phone Lines and Calling Routing Behavior

[sequence]

Enter characters within square brackets to create a list of accepted key presses. The user can press any one of the keys in the list.

• Numeric range For example, you would enter [2-9] to allow the user to press any one digit from 2 through 9.

• Numeric range with other characters For example, you would enter [35-8*] to allow the user to press 3, 5, 6, 7, 8, or *.

(period)

Enter a period for element repetition. The dial plan accepts 0 or more entries of the digit. For example,

01. allows users to

enter 0, 01, 011, 0111, and so on.

<dialed:substituted>

Use this format to indicate that certain dialed digits are replaced by other characters when the sequence is transmitted. The

dialed digits can be zero or more characters.

EXAMPLE 1: <8:1650>xxxxxxx

When the user presses 8 followed by a seven-digit number, the system automatically replaces the dialed 8 with 1650. If the user dials 85550112, the system transmits

16505550112.

EXAMPLE 2:

<:1>xxxxxxxxxx

In this example, no digits are replaced. When the user enters a 10-digit string of numbers, the number 1 is added at the beginning of the sequence. If the user dials 9725550112, the system transmits 19725550112

(comma)

Enter a comma between digits to play an “outside line” dial tone after a user-entered sequence.

EXAMPLE:

9, 1xxxxxxxxxx

An “outside line” dial tone is sounded after the user presses 9, and the tone continues until the user presses 1.

(exclamation point)

Enter an exclamation point to prohibit a dial sequence pattern.

EXAMPLE:

1900xxxxxxx!

The system rejects any 11-digit sequence that begins with

1900.

*xx

Enter an asterisk to allow the user to enter a 2-digit star code.

Enter S0 to reduce the timer to 0 so that the dialed digits are evaluated after 0 seconds.

Digit Sequence Examples

The following examples show digit sequences that you can enter in a dial plan.

In a complete dial plan entry, sequences are separated by a pipe character (|), and the entire set of sequences is enclosed within parentheses.

EXAMPLE:

( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9]

xxxxxxxxx | 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )

• Extensions on your system

EXAMPLE:

(

[1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9]

xxxxxxxxx | 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )

[1-8]xx Allows a user dial any three-digit number that starts with the digits 1 through 8.

If your system uses four-digit extensions, you would instead enter the following string:

[1-8]xxx

• Local dialing with seven-digit number

EXAMPLE: ( [1-8]xx |

9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9]

xxxxxxxxx | 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]111)

9, xxxxxxx After a user presses 9, an external dial tone sounds. The user can enter any

seven-digit number, as in a local call.

• Local dialing with 3-digit area code and a 7-digit local number

EXAMPLE: ( [1-8]xx | 9, xxxxxxx |

9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9]

xxxxxxxxx | 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )

9, <:1>[2-9]xxxxxxxxx This example is useful where a local area code is required. After a

user presses 9, an external dial tone sounds. The user must enter a 10-digit number that begins with a digit 2 through 9. The system automatically inserts the 1 prefix before transmitting the number to the carrier.

• Local dialing with an automatically inserted 3-digit area code

EXAMPLE:

( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx |

8, <:1212>xxxxxxx | 9, 1 [2-9]

xxxxxxxxx | 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )

8, <:1212>xxxxxxx This is example is useful where a local area code is required by the

carrier but the majority of calls go to one area code. After the user presses 8, an external dial tone sounds. The user can enter any seven-digit number. The system automatically inserts the 1 prefix and the 212 area code before transmitting the number to the carrier.

• U.S. long distance dialing

EXAMPLE:

( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx |

9, 1 [2-9]

xxxxxxxxx

| 9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )

9, 1 [2-9] xxxxxxxxx

After the user presses 9, an external dial tone sounds. The user can

enter any 11-digit number that starts with 1 and is followed by a digit 2 through 9.

• Blocked number

EXAMPLE: ( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9]

xxxxxxxxx |

9, 1 900 xxxxxxx ! | 9, 011xxxxxx. | 0 | [49]11 )

9, 1 900 xxxxxxx ! This digit sequence is useful if you want to prevent users from dialing

numbers that are associated with high tolls or inappropriate content, such as 1-900 numbers in the U.S.. After the user press 9, an external dial tone sounds. If the user enters an 11-digit number that starts with the digits 1900, the call is rejected.

• U.S. international dialing

EXAMPLE:

( [1-8]xx | 9, xxxxxxx | 9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9]

xxxxxxxxx | 9, 1 900 xxxxxxx ! |

9, 011xxxxxx. | 0 | [49]11 )

9, 011xxxxxx. After the user presses 9, an external dial tone sounds. The user can enter

any number that starts with 011, as in an international call from the U.S.

• Informational numbers

EXAMPLE:

( [1-8]xx | 9, xxxxxxx |

9, <:1>[2-9]xxxxxxxxx | 8, <:1212>xxxxxxx | 9, 1 [2-9]

xxxxxxxxx | 9, 1 900 xxxxxxx ! |

9, 011xxxxxx. |

0 | [49]11 )

0 | [49]11

This example includes two digit sequences, separated by the pipe character. The first sequence allows a user to dial 0 for an operator. The second sequence allows the user to enter 411 for local information or 911 for emergency services.

Acceptance and Transmission the Dialed Digits

When a user dials a series of digits, each sequence in the dial plan is tested as a possible match. The matching sequences form a set of candidate digit sequences. As more digits are entered by the user, the set of candidates diminishes until only one or none are valid. When a terminating event occurs, the SPA9000 either accepts the user-dialed sequence and initiates a call, or else rejects the sequence as invalid. The user hears the reorder (fast busy) tone if the dialed sequence is invalid.

The following explains how terminating events are processed.

Terminating Event Processing

The dialed digits do not match any sequence in the dial plan.

The number is rejected.

The dialed digits exactly match one sequence in the dial plan.

• If the sequence is allowed by the dial plan, the number is accepted and is transmitted according to the dial plan.

• If the sequence is blocked by the dial plan, the number is rejected.

Setting the Timers for the Dial Plan

The system uses dial plan timers to determine when a user’s entry (or a null entry) is evaluated. You can modify the timers for an entire dial plan or for individual sequences within a dial plan.

There are three types of control timers:

•

”Dial Plan Timer (Off-Hook Timer),” on page 60

• ”Interdigit Long Timer (Incomplete Entry Timer),” on page 61

• ”Interdigit Short Timer (Complete Entry Timer),” on page 61

Linksys Voice System Administration Guide 60

Configuring Dial Plans

Configuring Phone Lines and Calling Routing Behavior

Dial Plan Timer (Off-Hook Timer)

You can think of the Dial Plan Timer as “the off-hook timer.” This timer starts counting when the phone goes off hook. If no digits are dialed within the specified number of seconds, the timer expires and the null entry is evaluated. Unless you have a special dial plan string to allow a null entry, the call is rejected. The default value is 5.

Syntax for the Dial Plan Timer

SYNTAX: (Ps<:n> | dial plan )

• s: The number of seconds; if no number is entered after P, the default timer of 5 seconds

applies.

• n: (optional): The number to transmit automatically when the timer expires; you can

enter an extension number or a DID number. No wildcard characters are allowed because the number will be transmitted as shown. If you omit the number substitution, <:n>, then the user hears a reorder (fast busy) tone after the specified number of seconds.

Examples for the Dial Plan Timer

• Allow more time for users to start dialing after taking a phone off hook.

EXAMPLE:

(

P9 | (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx)

P9 After taking a phone off hook, a user has 9 seconds to begin dialing. If no digits are

pressed within 9 seconds, the user hears a reorder (fast busy) tone. By setting a longer timer, you allow more time for users to enter the digits.

• Create a hotline for all sequences on the System Dial Plan

EXAMPLE:

(

P9<:23> | (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxx | 9,8,011xx. |

9,8,xx.|[1-8]xx)

P9<:23> After taking the phone off hook, a user has 9 seconds to begin dialing. If no

digits are pressed within 9 seconds, the call is transmitted automatically to extension 23.

• Create a hotline on a line button for an extension

EXAMPLE:

( P0 <:1000>)

With the timer set to 0 seconds, the call is transmitted automatically to the specified extension when the phone goes off hook. Enter this sequence in the Phone Dial Plan for Ext 2 or higher on a client station.

Configuring Dial Plans

Configuring Phone Lines and Calling Routing Behavior

Interdigit Long Timer (Incomplete Entry Timer)

You can think of this timer as the “incomplete entry” timer. This timer measures the interval between dialed digits. It applies as long as the dialed digits do not match any digit sequences in the dial plan. Unless the user enters another digit within the specified number of seconds, the entry is evaluated as incomplete, and the call is rejected. The default value is 10 seconds.

Note This section explains how to edit a timer as part of a dial plan.

Alternatively, you can modify the Control Timer that controls the default interdigit timers for all calls. See

”Editing the Control Timers for the

Default Interdigit Values,” on page 62.

Syntax for the Interdigit Long Timer

SYNTAX: L:s, ( dial plan )

• s: The number of seconds; if no number is entered after L:, the default timer of 5

seconds applies.

• Note that the timer sequence appears to the left of the initial parenthesis for the dial

plan.

Example for the Interdigit Long Timer

EXAMPLE:

L:15, (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx)

L:15,

This dial plan allows the user to pause for up to 15 seconds between digits before the Interdigit Long Timer expires. This setting is especially helpful to users such as sales people, who are reading the numbers from business cards and other printed materials while dialing.

Setting the Interdigit Long Timer for the System Dial Plan

Follow the procedure

”Editing the System Dial Plan,” on page 57.

Interdigit Short Timer (Complete Entry Timer)

You can think of this timer as the “complete entry” timer. This timer measures the interval between dialed digits. It applies when the dialed digits match at least one digit sequence in the dial plan. Unless the user enters another digit within the specified number of seconds, the entry is evaluated. If it is valid, the call proceeds. If it is invalid, the call is rejected. The default value is 3 seconds.

Note This section explains how to edit a timer as part of a dial plan.

Alternatively, you can modify the Control Timer that controls the default interdigit timers for all calls. See

”Editing the Control Timers for the

Default Interdigit Values,” on page 62.

Linksys Voice System Administration Guide 62

Configuring Dial Plans

Configuring Phone Lines and Calling Routing Behavior

Syntax for the Interdigit Short Timer

• SYNTAX 1: S:s, ( dial plan )

Use this syntax to apply the new setting to the entire dial plan within the parentheses.

• SYNTAX 2: sequence Ss

Use this syntax to apply the new setting to a particular dialing sequence.

– s: The number of seconds; if no number is entered after

S, the default timer of 5

seconds applies.

Examples for the Interdigit Short Timer

• Set the timer for the entire dial plan.

EXAMPLE:

S:6, (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx)

S:6, While entering a number with the phone off hook, a user can pause for up to 15

seconds between digits before the Interdigit Short Timer expires. This setting is especially helpful to users such as sales people, who are reading the numbers from business cards and other printed materials while dialing.

• Set an instant timer for a particular sequence within the dial plan.

EXAMPLE:

(9,8<:1408>[2-9]xxxxxx |

9,8,1[2-9]xxxxxxxxxS0 | 9,8,011xx. | 9,8,xx.|[1-8]xx)

9,8,1[2-9]xxxxxxxxxS0

With the timer set to 0, the call is transmitted automatically when

the user dials the final digit in the sequence.

Managing the Line Selection for Outbound Calls

When a user places an outbound call, the SPA9000 chooses a line based on the group membership of the station and the Call Routing Rule for the line interface. You can configure the settings to route calls through particular lines, based on factors such as the dialed number, the destination, or the corporate identity that you want to represent.

This section includes the following topics:

• ”Line Availability,” on page 63

• ”Configuring a Call Routing Rule,” on page 63

• ”Entering a Call Routing Rule,” on page 65

Line Availability

The SPA9000 considers a line to be available for an outgoing call if the following conditions are met:

• The line is enabled in the configuration and is functioning. See

”Configuring Line

Interfaces on the SPA9000,” on page 46

• The line is authorized by the Call Routing Rule for the dialed number. See

”Configuring a

Call Routing Rule,” on page 63

• The line has capacity to take more calls. See

”Configuring Call Capacity for a Line

Interface,” on page 51

• The Dial Plan for this line allows the dialed number. See

”Configuring Dial Plans,” on

page 52

Configuring a Call Routing Rule

A Call Routing Rule is a special dial plan that specifies the lines that can be used to transmit a dialed number. The same number pattern can apply to more than one line.

SYNTAX:

( <:Lw,x,y,z>number-pattern | <:Lw,x,y,z >number-pattern | <:Lw,x ,y,z>number-pattern |

<:Lw,x, y,z>number-pattern )

• L: A signifier for “Line”

Linksys Voice System Administration Guide 64

Managing the Line Selection for Outbound Calls

Configuring Phone Lines and Calling Routing Behavior

• w, x, y, z: The number of the line interface (L1 for Line 1, L2 for Line 2, and so on)

• number-pattern: The dialed sequence that can use the specified lines

• Other elements:

– Enclose the entire call routing rule in parentheses.

– Use a comma to separate each digit sequence within a number-pattern.

– Use a pipe character (|) to separate each call routing rule.

Note The Call Routing rules use the same digit sequences as the Dial Plan

rules. See Table 4-2, ‘Digit Sequences and Functions,” on page 53.

• Any line interface can be used for allowed digit sequences

EXAMPLE:

(<:L1,2,3,4>9xx.)

Any line interface can be used for any dialed sequence that begins with 9 and includes at least two additional numbers. The SPA9000 chooses an available line from the list, proceeding in the listed order. See

Table 4-2, ‘Digit Sequences and Functions,” on

page 63

• Different line interfaces for U.S., international, and 1-800 numbers

EXAMPLE: (<:L1,2>9xx. | <:L3>011852xx. | <:L4>1800xxxxxxx )

This example has three parts:

–

<:L1,2>9xx. Line 1 and Line 2 can be used if the sequence starts with 9 and includes

at least two additional digits.

– <:L3>011852xx. Line 3 can be used if the sequence starts with 011852 and includes

at least two additional digits.

–

<:L4>1800xxxxxxx Line 4 can be used if the sequence starts with 1800 and

includes at least seven additional digits.

• Separate lines for long distance and local calling

EXAMPLE:

(<:L1>9xx. | <:L2>8xx.)

Line 1 is used for any dialed sequence that starts with 9. Line 2 is used for any dialed sequence that starts with 8. This call routing rule is effective if users understand that 9 is the steering digit for long distance (with Line 1 configured for the ITSP and its inexpensive long distance service) and that 8 is the steering digit for local calls (with Line 2 configured for a SPA400 that has local phone lines connected).

• Wildcard characters

EXAMPLE:

(<:L1>51*,577?)

Linksys Voice System Administration Guide 65

Managing Caller ID Settings for Outgoing Calls

Configuring Phone Lines and Calling Routing Behavior

In this example, Line 1 can be used when either of the following number patterns is dialed:

– The user dials a number that starts with 51, followed by any other characters.

– The user dials any four-digit number starting with 577.

4. In the Call Routing Rule field, enter the rule that you want to apply

5. Click Submit All Changes.

6. To verify your progress, place a call to a phone that has caller ID, and confirm that the

expected number appears.

Managing Caller ID Settings for Outgoing Calls

By default, outgoing calls through an ITSP line are identified by the User ID (usually the phone number) and Display Name of the selected line interface. Alternatively, you can map a DID number to a phone extension so that all outbound calls from that extension will identify the caller by the DID number and the assigned phone display name. (See

”Supporting Multiple DID

Numbers Per Line Interface,” on page 68

Note Caller ID for a PSTN line is controlled by the phone company. Caller ID

through an ITSP line should work as described, but if not, contact your ITSP to see what is allowed for caller ID configuration.

1. Connect to the SPA9000 administration web server, and choose Admin access with

Advanced settings. (See

”Connecting to the SPA9000 Administration Web Server,” on

Managing Inbound Calls with the Contact List

Configuring Phone Lines and Calling Routing Behavior

Managing Inbound Calls with the Contact List

You can use the Contact List to route inbound calls to the Auto Attendant, to a receptionist, to a client station, to a group of stations, or to a combination of these.

•

”Routing an Inbound Call to the Auto Attendant,” on page 66

• ”Routing an Inbound Call to a Receptionist or Client Stations,” on page 66

• ”Example Contact List Rules,” on page 66

• ”Entering a Contact List Rule,” on page 70

Routing an Inbound Call to the Auto Attendant

By default, all inbound calls are routed to the Auto Attendant (aa). This automated system answers inbound calls by playing pre-recorded voice message that asks the caller to enter the desired extension. If you want only the Auto Attendant to receive a call, keep the default setting, aa, in the Contact List field on the Voice > Line N page, Subscriber Information section, for each line interface. For more information, see

Chapter 7, "Configuring the LVS Auto-Attendant.".

Routing an Inbound Call to a Receptionist or Client Stations

You can route an inbound call to a receptionist or to client stations by using a Contact List. You specify the Contact List for each line interface (Line 1, Line 2, Line 3, Line 4). For example, if Line 1 is configured for an ITSP account, and a call is placed to a Direct Inward Dialing (DID) number for that account, then the call is routed to the Contact List that is specified on the Line 1 configuration page. Likewise, if Line 2 is configured for a SPA400 that has PSTN lines attached, and a call is placed to the associated PSTN phone number, then the call is routed as specified in the Voice > Line page, Subscriber Information section, Contact List field.

Example Contact List Rules

The following examples show rules that you can enter to route incoming calls.

Note The SPA9000 alerts all registered clients stations if * is used in the

Contact List (SPA9000 Voice > Line N page > Subscriber Information section).

• Routing calls to a receptionist

EXAMPLE:

100

An incoming call to any DID number on this line interface causes station 100 to ring. The receptionist answers the call. If the call is not answered, it automatically goes to the voice mailbox for station 100, assuming that voice mail is configured.

• Routing calls simultaneously to two or more stations

EXAMPLE:

100, 104

Linksys Voice System Administration Guide 67

Managing Inbound Calls with the Contact List

Configuring Phone Lines and Calling Routing Behavior

An incoming call to any DID number on this line interface causes station 100 and station 104 to ring. Either station can answer the call.

NOTE: The list of extension numbers may include * to represent multiple wildcard characters or ? to represent a single wildcard character. For example, 10? represents all stations numbered 100 through 109.

• Special routing for different DID numbers

EXAMPLE:

9725550155:100|9725550156:101, 102

An incoming call to 972-555-0155 causes station 100 to ring. An incoming call to 972555-0156 causes station 101 and station 102 to ring simultaneously.

Note In this example, the rules are separated by a pipe character (|) to indicate

an “or” condition.

• Routing calls to a station and forwarding unanswered calls to voice mail

EXAMPLE 1: 5300, cfwd=vm25300

An incoming call through this line interface causes station 5300 to ring. If there is no answer, the call is forwarded to the voice mail server on line interface 2, mailbox number

5300. The time interval is determined by the value Cfwd No Ans Delay field, which is located below the Contact List field on the Voice > Line page. The default value is 20 seconds.

EXAMPLE 2:

4085550122:5001|4085550123:5000,cfwd=aa

An incoming call to 408-555-0122 causes station 5001 to ring. An incoming call to 408555-0123 causes station 5000 to ring. If station 5000 does not answer its call, the call is forwarded to the Auto Attendant. The time interval is determined by the value Cfwd No Ans Delay field, which is located below the Contact List field. The default value is 20 seconds.

• Routing a call by ringing stations randomly

EXAMPLE:

530?,hunt=ra;10;2,cfwd=vm25404

An incoming call through this line interface causes one station in the group 5300 through 5309 to ring. The station is chosen randomly (

ra). After 10 seconds, if the call is

unanswered, then another station is chosen randomly from the remaining stations. The system cycles through the list two times. If the call is unanswered, it is forwarded to the voice mail server on line interface 2, mailbox 5404.

SYNTAX: hunt=algo;interval;max, cfwd=target

– algo: The order to ring the stations

restart (

re)—Always start from beginning of the list

next (ne)—Start from the next on the list to the last station that rings

Linksys Voice System Administration Guide 68

Managing Inbound Calls with the Contact List

Configuring Phone Lines and Calling Routing Behavior

random (ra)—Order is randomized for each call

– interval: The number of seconds to ring each station

– max: The total time in seconds or the total number of cycles to elapse before the call

is rejected or forwarded to the target. If max is less than interval, it is interpreted as the number of cycles. If max is 0, hunting goes on indefinitely until the caller hangs up or some one answers the call.

NOTE: You also can create a hunt group that acts as a separate extension within the system. For more information, see

”Managing Inbound Calls with Hunt Groups,” on

page 73

Supporting Multiple DID Numbers Per Line Interface

An ITSP can provide a block of DID numbers, for example with a main number of 4085553000, and additional DID numbers from 4085553001–4084443009. The ITSP can identify the local client stations to which an external incoming call should be routed. Linksys recommends including this information in the TO header of the incoming INVITE while the request-URI is addressed to the line interface user-id. In the INVITE, the ITSP indicates the DID number in the TO header user-id field.

EXAMPLE SIP Header 1:

INVITE sip:4089993000@itsp1.com SIP/2.0

To: <sip:4089993003@itsp1.com>

Alternatively, the DID number can be indicated as a parameter in the TO header with a configurable parameter name, such as

didn.

EXAMPLE SIP Header 2:

INVITE sip:4089993000@itsp1.com SIP/2.0

To: <sip:4089993000@itsp1.com>;didn=4089993003

You can identify the field to use for the DID number and the parameter name on the Voice > SIP page, PBX Parameters section, SIP DIDN and SIP DIDN Param Name fields. For the first example above, these two fields are ignored; for the second example, SIP DIDN is set to TO Param and SIP DIDN Param Name is set to didn.

The Contact List is used to route the calls to a client station based on DID numbers that are embedded in the INVITE message.

EXAMPLE Contact List Rule:

4089993000:aa|4089993001:3001|4089993002:3002|…|4089993009:3009

Linksys Voice System Administration Guide 69

Managing Inbound Calls with the Contact List

Configuring Phone Lines and Calling Routing Behavior

An incoming call to the main number is answered by the Auto-Attendant, while calls to the other nine DID numbers are routed to dedicated private extensions.

Supporting Direct Inward Dialing to Phone Extensions

Direct Inward Dialing allows the external users to dial directly any phone extension in the LVS system, without passing through the Auto Attendant or the receptionist.

Before proceeding with the configuration you need to have the full correspondence between the external (DID) number and the extension number.

Table 4-3 provides an example.

Table 4-3 DID-to-Extension Mapping Example

NOTE:

• Direct Inward Dialing requires network support for SIP trunking DID.

• It is important that the DID number format match exactly the format of the number signaled in the SIP trunk.

• Please check with your Service Provider to confirm the availability of this feature and the correct DID number format, before proceeding with this configuration.

SYNTAX:

EXAMPLE:

4085555550:aa|4085555551:+101|4085555552:+102|4085555553:+103|4085555554:+104|408555565 0:+500|

• Enter a plus (+) or a minus (-) before the extension number to achieve the desired results for caller ID and call routing:

– + <Extn1> The extension will be alerted when there is an incoming call to the DID

number, and the DID number will be used as the local user-ID in outbound SIP requests, along with the display-name of the extension.

• Extn#: Target extension number or a for Auto Attendant

• Default route: The default route (extension, hunt group or Auto Attendant) to be used in case the incoming target number does not match any of the DID numbers in the contact list with the format described in the sections above.

• Call forwarding: Optionally, add call forward information to the Contact List to specify how unanswered calls are handled.

NOTE: It is useful to add call forward information to ensure that calls are answered when the designated phone is unstaffed, as may be the case during lunch time or after hours. In this case, if the call is not answered within a specified time, the call is routed to another phone or to the Auto Attendant.

Call Transfer Support on SPA9000

•

”Call Forward Bridge Mode,” on page 72

• ”Call Transfer Bridge Mode,” on page 72

Call Forward Bridge Mode

The normal way of performing the call forwarding operation is for the SPA9000 to send a (blind) SIP REFER to the calling device to let it contact the target number directly. It then drops out of the call completely. This requires the calling device to understand the SIP signaling involved and the operation permitted by the underlying service provider. The SPA400 cannot handle this operation.

With bridging, the SPA9000 maintains two separate call legs throughout the call: one with the caller and one with the call forward target. The two call peers connect only with the SPA9000, while the SPA9000 acts as a proxy for the RTP packets exchanged between the two parties.

On the Voice > Line N page, Proxy and Registration section, the CWFD Bridge Mode field has two possible values:

• none—Do not bridge forwarded calls (use the normal REFER method)

• all—Bridge all forwarded calls

Call Transfer Bridge Mode

The normal way of performing this operation is for the SPA9000 to send a SIP REFER method to the calling device to let it contact the transfer target directly. The SPA9000 then drops out of the call completely. This requires the calling device (the transferee) and the target device to understand the SIP signaling involved and the operation permitted by the underlying service providers. Note that the call legs with transferee and the transfer target might be with different ITSP. The SPA400, for instance, cannot handle this operation.

With bridging, the SPA9000 maintains two separate call legs throughout the call: one with the transferred call and one with the transfer target. The two call peers connect only with the SPA9000, while the SPA9000 acts as a proxy for the RTP packets exchanged between the two parties.

On the Voice > Line N page, Proxy and Registration section, the XFER Bridge Mode field has three possible values:

• none —Do not bridge call transfer (use the normal REFER method)

• all —Bridge all call transfer

• all except same line—Bridge call transfer only if it is between two different line

Managing Inbound Calls with Hunt Groups

Configuring Phone Lines and Calling Routing Behavior

Managing Inbound Calls with Hunt Groups

A Hunt Group is a group of client stations that are treated as one extension for the purpose of managing inbound calls. The client stations in the hunt group can be alerted simultaneously or sequentially. The first client station to pick up the call establishes a private connection to the caller.

You can configure two types of Hunt Groups:

•

”Hunt Group that Rings All Stations Simultaneously,” on page 73

• ”Hunt Group that Rings Stations Individually,” on page 75

Note Compare a Shared Line Appearance to a Hunt Group. A Hunt Group may

ring several stations simultaneously, but only one station can answer and manage the call. A Shared Line Appearance also rings multiple lines simultaneously but allows multiple stations to share and manage the call. For more information, see

”Managing Inbound Calls with Shared Line

Appearances,” on page 77.

Hunt Group that Rings All Stations Simultaneously

You can create a hunt group that simultaneously rings all stations in the group. Optionally, you can assign a name to the group or use wildcard characters to create the list of stations in the group.

Syntax for a “Ring All Stations” Hunt Group Rule

The basic syntax for this type of group is shown below. Optionally, you can assign a name to the group.

SYNTAX:

ext-in:name=groupname,hunt-list

• ext-in (required): The extension number that users dial to contact this group

• name (optional): The name of the group, which appears in the Corporate Directory on

the phones

• hunt-list (required): The station numbers that participate in this group, separated by

commas

NOTE: To create multiple groups, separate the hunt group rules by typing the pipe character: |

Examples of “Ring All Stations” Hunt Group Rules

• Contacting a group of stations simultaneously

EXAMPLE:

500:101,102,103

This hunt group is assigned a number (500:). The group includes three stations (101,102,103). A call to extension 500 rings all three stations simultaneously.

Linksys Voice System Administration Guide 74

Managing Inbound Calls with Hunt Groups

Configuring Phone Lines and Calling Routing Behavior

• Creating a named hunt group

EXAMPLE: 500:name=TechSupport,101,102,103

This hunt group is assigned a number (500:) and a name (name=TechSupport). The group includes three stations (101,102,103). A call to extension 500 rings all three stations simultaneously.

• Wildcards in Hunt List

EXAMPLE 1: 500:10?

In this example, the ? symbol is a wildcard character that represent any single digit. A call to extension 500 simultaneously rings all stations 100 through 109.

EXAMPLE 2:

500:1*

In this example, the * symbol is a wildcard character that represents any number of digits. A call to extension 500 simultaneously rings all stations that begins with the number 1.

EXAMPLE:

500:name=TechSupport,1*

In this example, the group has a name, Tech Support. The * symbol is a wildcard character that represents any number of digits. A call to extension 500 simultaneously rings all stations that begins with the number 1.

• Creating multiple hunt groups

EXAMPLE:

500:name=TechSupport,101,102,103|600:name=AccountSupport,2*|

Two hunt groups are created and are assigned names. A call to extension 500 simultaneously rings stations 101, 102, and 103. A call to extension 600 simultaneously rings all stations that begin with the number 2.

Creating a Hunt Group to Ring All Stations

1. Connect to the SPA9000 administration web server, and choose Admin access with Advanced settings. (See

”Connecting to the SPA9000 Administration Web Server,” on

page 24

2. Click Voice tab > SIP.

3. Scroll down to the PBX Parameters section.

4. In the Hunt Groups field, type your hunt group rule. See

Hunt Group that Rings Stations Individually

You can create a hunt group that rings the stations individually, in sequential order or random order. You need to set the ring interval and the maximum number of cycles or seconds to occur before a call is transferred to voice mail.

Syntax for a “Ring Individual Stations” Hunt Group Rule

The syntax for a “ring individual stations” hunt group rule is shown below. Optionally, you can assign a name to the group.

SYNTAX:

ext-in:name=groupname,hunt-list,type=algo;ring-interval;max,cfwd=ext-fwd

• ext-in (required): The extension number that users dial to contact this group

•

name (optional): The name of the group, which appears in the Corporate Directory on

the phones

• hunt-list (required): The station numbers that participate in this group, separated by

commas

•

type (required to ring individual stations): The type of routing among the stations in the

group

–

re (sequentially from the beginning): Every incoming call is routed to the first station

in the list. If the call is unanswered, it cycles through the stations in the listed order. The syntax is hunt=re.

–

ne (sequentially from the next station): An incoming call is routed by determining

which station most recently answered a call for this group. The new call is routed to the station that is next in the list. If the call is unanswered, it cycles through the stations in the listed order. The syntax is hunt=ne.

–

ra (random): An incoming call is routed randomly to any listed station. If the call is

unanswered, it cycles through the stations in random order. The syntax is hunt=ra.

•

ring-interval (required to ring individual stations): The number of seconds that elapse

before an unanswered call is routed to another station in the group

•

max (required to ring individual stations): Either the maximum number of cycles or the

total number of seconds that elapse before an unanswered call is forwarded to the cfwd destination. If the max value is less than the ring interval, it is interpreted as the number of cycles. If the max value is greater than the ring interval, it is interpreted as the total number of seconds.

• cfwd (required to ring individual stations): The Call Forward destination for an

unanswered call. The destination can be another station, a voice mailbox, or the Auto Attendant.

NOTE: Wildcard characters can be used in the hunt list. Multiple groups can be entered, using the pipe character as a separator.

Linksys Voice System Administration Guide 76

Managing Inbound Calls with Hunt Groups

Configuring Phone Lines and Calling Routing Behavior

Examples of “Ring Individual Stations” Hunt Group Rules

• “From the Beginning” Order with Forwarding to the Auto Attendant

300:name=TechSupport,101,102,100,hunt=re;20;2,cfwd=aa

This hunt group is assigned an extension number (300:) and a name (

name=TechSupport,). The group includes three stations (101,102,100,). Calls are routed

sequentially from the beginning of the list (

hunt=re;). Every new call is routed to station

101. If the call is unanswered, it cycles to station 102 and then to station 100. Each phone rings for 20 seconds (

20;). After 2 cycles elapse, an unanswered call is forwarded

to the Auto Attendant (

, cfwd=aa).

• Random Order with Forwarding to a Voice Mailbox

400:name=Sales,101,102,103,hunt=ra;30;1,cfwd=vm2100

This hunt group is assigned an extension number (400:) and a name (name=Sales,). The group includes three stations (

101,102,103,). Calls are routed in random order (hunt=ra;).

A new call is routed to a randomly chosen station. If the call is unanswered, it cycles through the stations in random order. Each phone rings for 30 seconds (

30;). After 1

cycle is completed, an unanswered call is forwarded to the voice mail for station 100, where Line 2 is configured for the voice mail service (

1,cfwd=vm2100).

• “Next Station” Order with Forwarding to a Station

500:name=Scheduling,102,103,101,hunt=ne;45;240,cfwd=100

This hunt group is assigned an extension number (500:) and a name (name=Scheduling,). The group includes three stations (

102,103,101,). Calls are routed in “next station” order

unt=ne;). Suppose that station 103 answered the most recent call. A new call is routed

to the next station in the list, which is station 101. If the call is unanswered, then it cycles to station 102, and so on. Each phone rings for 45 seconds (45;). After a total of 240 seconds has elapsed, the call is forwarded to station 100 (240,cfwd=100).

• Multiple Lines with Wildcard Characters

400:name=CustomerService,10?,hunt=re;20;2,cfwd=aa|500:name=Sales,20?,hunt=ra;30;1, cfwd=vm100| 600:name=TechSupport,300,301,302,hunt=ne;45;3,cfwd=100|

Three hunt groups are created. A call to extension 400 rings stations 100 to 109 in “from the beginning order.” A call to extension 500 rings stations 200 to 209 in random order. A call to extension 600 rings the listed stations in “next station” order.

5. Click Submit All Changes. The SPA9000 and the phones reboot.

6. To verify the settings, place a call to the extension that you created. Verify that member stations ring in the desired order, with the desired ring interval, maximum cycles, and call forwarding.

Managing Inbound Calls with Shared Line Appearances

A shared line appearance (SLA) allows multiple stations to share an extension number and to manage a call as a group.

About Shared Line Appearances

An incoming call to an SLA causes all stations to ring simultaneously. The phones display the line status, such as idle, ringing, or busy.

NOTE:

• If a shared line is being used by one of the stations in the group, no one can use the

corresponding line key until the line is released. A message appears on the phone display to indicate that a shared call is active.

• All stations with a line key for the SLA can monitor the status based on the appearance

of the line key button:

– Green: The SLA is available.

– Flashing Red Quickly: A call is ringing the SLA and has not been answered.

– Flashing Red Intermittently: A call is active at another station.

– Flashing Red Slowly: A call is on hold.

– Solid Red: A call is active on this station.

• All stations with a display can monitor the status of any SLA that is configured. The icon

next to the line key will change to show ringing, off-hook, or busy "<-->" until the phone is back on-hook.

• Comparing the SLA to a Hunt Group, both may ring several stations simultaneously.

However, only one station in a Hunt Group can answer and manage the call. For more information, see

”Managing Inbound Calls with Hunt Groups,” on page 73.

Configuring a SPA400 for PSTN Access

Typically, there is no need to change the default settings on the Voice page. Make changes only if a problem is suspected and only after consulting with a service technician from your telephone service provider. It is essential that the settings on your system are compatible with those of the Central Office.

Configuring a SPA400 for Voice Mail Service

The SPA400 includes a USB adapter with an integrated voice mail application for the users and extensions that are configured on the SPA9000. The integrated voice mail application server supports 32 configurable voice mail accounts. Although a SPA9000 can be configured with up to four SPA400 devices, only one SPA400 can be configured with the voice mail server.

Note Important: For optimum voice mail performance, a SPA400 should be

dedicated to the voice mail application when either of the following conditions is met:

1) More than 2 FXO connections are required —OR—

2) More than 2 users commonly access voice mail at the same time.

Note Before you begin any of the procedures in this section, configure a

SPA9000 line interface for this device. See
