Getting Started

This chapter introduces you to the SPA9000 Voice System by describing the components and presenting several deployment scenarios.

NOTE This chapter is essential reading before you begin installing the equipment or

configuring the system.

• “Introduction to the SPA9000 Voice System,” on page16

• “Deployment Scenarios,” on page18

• “Initial Installation, and Configuration,” on page 23

Introduction to the SPA9000 Voice System

The SPA9000 Voice System is an affordable and feature-rich IP telephone system that is designed especially for the Small and Home Office. The SPA9000 Voice System uses standard TCP/IP protocols and can provide global connectivity through any Internet Telephony Service Provider (ITSP) that supports the Session Initiation Protocol (SIP).

At minimum, the SPA9000 Voice System 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 SPA9000 Voice System can subscribe to ITSP services to take advantage of low calling rates. With the SPA400, the SPA9000 Voice System can connect to the Public Switched Telephone Network (PSTN) to support analog phone lines. See Figure 1 “SPA9000

Voice System with the SPA9000 and SPA400” on page17 to learn more about a

typical deployment.

SPA9000 Voice System Administration Guide 16

Getting Started

Introduction to the SPA9000 Voice System

Figure1 SPA9000 Voice System with the SPA9000 and SPA400

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 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.

SPA9000 Voice System Administration Guide 17

Getting Started

Deployment Scenarios

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 key presses according to the rules that are specified in the Auto Attendant script.

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 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.

IP Phones and Accessories

The SPA9000 Voice System supports any of the Cisco SPA900 Series SIP IP Phones, as well as the Cisco WIP310 Wireless IP Phone.

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

SPA9x2 Phone Administration Guide, the SPA9x2 Phone User Guide, and the Cisco Wireless-G IP Phone User Guide.

Deployment Scenarios

The SPA9000 Voice System can meet the calling needs of many small businesses. Various deployment scenarios are possible. This section includes the following examples:

• “PSTN Access and Local Voice Mail,” on page19

• “ITSP Service Only,” on page 20

Setting Up the WAN Connection for the SPA9000

The SPA9000 becomes a DHCP client of any server on the network. The recommended setting is to use a static IP address. This configuration provides ease of installation and prevents connectivity issues that would occur if the IP address of the SPA9000 changed.

STEP 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 27.)

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.

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 SPA9000 Voice System Installation and Configuration Guide.

SPA9000 Voice System Administration Guide 33

Setting the Multicast Address

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

• Graceful reboot: The device reboots when there are no calls in progress.

• Immediate reboot: The device reboots immediately.

• Graceful restart: The device restarts when there are no calls in progress.

• Immediate restart: The device restarts immediately.

• Group page start: One-way audio is sent from the caller to all other phones.

• Group page end: An active page is terminated.

• Get ringing calls: When a user chooses Group Pickup on a phone, the SPA9000

gathers information about all ringing phones and reports this information to the requesting phone.

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.

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.

• You can deploy a syslog server to receive syslog messages from the device,

which acts as a syslog client. The syslog client device uses the syslog protocol to send messages, based on its configuration, to a syslog server. The syslog messages can be accessed by reviewing the "syslog.514.log" file which resides in the same directory as the slogsrv.exe syslog server application.

About the SPA9000 Voice System and SIP

The SPA9000 Voice System is implemented using open standards, such as Session Initiation Protocol (SIP), to help ensure interoperability 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. Figure1, “SIP Requests and Responses

for Internal Calls,” on page 48 illustrates the SIP requests and responses between

client stations in the SPA9000 Voice System. 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.

Likewise, SIP requests and responses are exchanged to support outbound and inbound calls that are handled through the ITSP service. In Figure 2, “SPA9000 as a

SIP Proxy for Internet Calls,” 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.

Configuring Your System for ITSP Interoperability

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 49

• “NAT Mapping with SIP-ALG Router,” on page 49

• “Configuring NAT Mapping with a Static IP Address,” on page 49

• “Configuring NAT Mapping with STUN,” on page 51

NAT Mapping with Session Border Controller

It is strongly recommended that you choose an ITSP that supports NAT mapping through a Session Border Controller. With NAT mapping provided by the ITSP, you have more choices in selecting a router.

NAT Mapping with SIP-ALG Router

If the ITSP network does not provide a Session Border Controller functionality, you can achieve NAT mapping by using a router that has a SIP ALG (Application Layer Gateway). The WRV200 router is recommended for this purpose, although any router with a SIP-ALG can be used. By using a SIP-ALG router, you have more choices in selecting an ITSP.

Configuring NAT Mapping with a Static IP Address

If the ITSP network does not provide a Session Border Controller functionality, and if other requirements are met, you can configure NAT mapping to ensure interoperability with the ITSP.

SPA9000 Voice System Administration Guide 49

Configuring Your System for ITSP Interoperability

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

Requirements:

• You must have an external (public) IP address that is static.

• The NAT mechanism used in the router must be symmetric. See “Determining

Whether the Router Uses Symmetric or Asymmetric NAT,” on page 53.

• The LAN switch must be configured to enable Spanning Tree Protocol and Port

Fast on the ports to which the SPA devices are connected.

NOTE Use NAT mapping only if the ITSP network does not provide a Session Border

Controller functionality.

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

Advanced settings.

STEP 2 Click Voice tab > SIP.

STEP 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

If the ITSP network does not provide a Session Border Controller functionality, and if other requirements are met, it is possible to use STUN as a mechanism to discover the NAT mapping. This option is considered a practice of last resort and should be used only if the other methods are unavailable.

Requirements:

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

“Determining Whether the Router Uses Symmetric or Asymmetric NAT,” on page 53.

• You must have a computer running STUN server software.

• The LAN switch must be configured to enable Spanning Tree Protocol and Port

Fast on the ports to which the SPA devices are connected.

NOTE You also need to configure the firewall settings on your router to allow SIP

traffic. See “Firewalls and SIP,” on page 54.

Determining Whether the Router Uses Symmetric or Asymmetric NAT

STUN does not work on routers with symmetric NAT. With symmetric NAT, IP addresses are mapped from one internal IP address and port to one external, routable destination IP address and port. If another packet is sent from the same source IP address and port to a different destination, then a different IP address and port number combination is used. This method is restrictive because an external host can send a packet to a particular port on the internal host only if the internal host first sent a packet from that port to the external host.

NOTE This procedure assumes that a syslog server is configured and is ready to receive

syslog messages.

STEP 1 Make sure you do not have firewall running on your PC that could block the syslog

port (port 514 by default).

You can configure the following types of services on the SPA9000 line interfaces:

• ITSP service: Up to 16 DID numbers can be supported on each line interface.

You can configure different ITSP accounts on different line interfaces.

• PSTN service: You can configure a line interface to register the SPA9000 with

a SPA400 to support PSTN lines.

• SPA400 voice mail service: You can configure a line interface to register the

SPA9000 with a SPA400 to support voice mail server. This SPA400 should have no more than two PSTN lines connected. If more than two PSTN lines and voice mail are required, you should reserve one SPA400 exclusively for voice mail. Exceeding these guidelines will affect the quality of voice mail playback and command recognition.

• ISDN services: You can configure a line interface to register the SPA9000 with

a Mediatrix® 4400 ISDN BRI Digital gateway. For more information, refer to the SPA9000/Mediatrix® 440X ISDN Gateway Configuration Guide. Partners can find this guide by going to Cisco Partner Central, Voice & Conferencing page, Technical Resources section. Use the following URL:

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

You can configure a line interface to register the SPA9000 to a SPA400 for PSTN access or voice mail service. To enable the interoperation of the SPA9000 and the SPA400, you need to enter corresponding information on the SPA9000 Voice > Line page and on the SPA400 Setup > SPA9000 Interface page. For voice mail service, also configure the SPA400 Setup > Voicemail Server page.

Before you configure a line interface, be aware of the following factors:

• The SPA9000 registers to the SPA400. Therefore, the SPA400 must be

connected and available when the SPA9000 attempts to register to it.

• If you have not yet set a static IP address for the SPA400, you will need to know

the DHCP-obtained IP address. Review the DHCP client list on the router.

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.

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 Cisco SPA 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.

The following table provides the approximate bandwidth budget for different codecs.

Configuring Dial Plans

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 table explains how terminating events are processed.

Ter min ati ng E ve nt Processing

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

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

The number is rejected.

• 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.

A timeout occurs. The number is rejected if the dialed digits are

not matched to a digit sequence in the dial plan within the time specified by the applicable interdigit timer.

• The Interdigit Long Timer applies when the

dialed digits do not match any digit sequence in the dial plan. The default value is 10 seconds.

• The Interdigit Short Timer applies when the

dialed digits match one or more candidate sequences in the dial plan. The default value is 3 seconds.

The user presses the # key or the dial softkey on the phone display.

• If the sequence is complete and is allowed by

the dial plan, the number is accepted and is transmitted according to the dial plan.

• If the sequence is incomplete or is blocked by

the dial plan, the number is rejected.

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: (P s<: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: ( | 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.

P9 | (9,8<:1408>[2-9]xxxxx x | 9,8,1[2-9]xxxxxxxxx

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

EXAMPLE: ( 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.

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

“Resetting the Control Timers,” on page 77.

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.

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.

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:

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.

S:6, (9,8<:1408>[2-9]xxxx xx | 9,8,1[2-9]xxxxxxxxx |

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

EXAMPLE: (9,8<:1408>[2-9]xxxxxx | 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 feature can be used whether the SPA9000 line interface is configured for an ITSP or a SPA400 voice gateway.

This section includes the following topics:

• “Line Availability,” on page 78

• “Configuring a Call Routing Rule,” on page 79

• “Entering a Call Routing Rule,” on page 81

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 58.

• The line is authorized by the

for the dialed number.

• The line has capacity to take more calls. See “Configuring Call Capacity for a

Line Interface,” on page 63.

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

Plans,” on page 66.

Configuring Phone Lines and Calling Routing Behavior

Managing the Line Selection for Outbound Calls

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”

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

• port: The port number

NOTE This parameter applies only if the line interface is configured for a SPA400.

• 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

“Digit Sequences,” on page 66.

• Allowing any line interface to be used

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 “Line Availability,” on

page 78.

SPA9000 Voice System Administration Guide 79

Configuring Phone Lines and Calling Routing Behavior

Managing the Line Selection for Outbound Calls

• 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).

• Specifying a hunt order for FXO lines on one SPA400 unit

EXAMPLE: (<:L2{1,2}>8xx)

Line 2 is configured for a SPA400. This line is used for any dialed sequence that starts with 8. The preference is to seize port 1. If port 1 is unavailable, the next preference is to seize line 2. If neither port is available, then the call fails.

• Specifying a hunt order for FXO lines on multiple SPA400 units

EXAMPLE: (<:L4{1},3,2{2,4}>9xx)

Lines 2, 3, and 4 are configured for SPA400 units. These lines are used for any dialed sequence that starts with 9. The preference is to use Line 4, port 1. If it is unavailable, then any port on Line 3 can be used. If Line 3 is unavailable, then the next choice is Line 2, port 2. If it is unavailable, the next choice is Line 2, port

4. If it is unavailable, then the call fails.

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 87.)

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.

Configuring Phone Lines and Calling Routing Behavior

Call Transfer Support on SPA9000

You can configure the bridge mode for call forward and call transfer.

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 between different line interfaces

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 85

• “Routing an Inbound Call to a Receptionist or Client Stations,” on page 85

• “Example Contact List Rules,” on page 86

• “Entering a Contact List Rule,” on page 91

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 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 Line1 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.

SPA9000 Voice System Administration Guide 85

Configuring Phone Lines and Calling Routing Behavior

Managing Inbound Calls with the Contact List

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

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 972-555-0156 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.

SPA9000 Voice System Administration Guide 86

Configuring Phone Lines and Calling Routing Behavior

Managing Inbound Calls with the Contact List

• 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 408-555-0123 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 with a hunt rule

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.

NOTE A hunt rule in the contact list applies only to calls on the selected line

interface. You also can create hunt groups that apply to all lines. For more information and additional examples of syntax that can be used in a hunt rule in the Contact List, see “Managing Inbound Calls with Hunt Groups,” on

page 92.

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.

SPA9000 Voice System Administration Guide 87

Configuring Phone Lines and Calling Routing Behavior

Managing Inbound Calls with the Contact List

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|…|4089993009:3 009

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 SPA9000 Voice 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 1, “DID-to-Extension Mapping Example,” on page 89 provides an example.

Be aware of the following factors:

• 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.

• 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.

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.

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.

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 98.

There are two types of hunt rules:

• Global Hunt Rule: The hunt rule applies to all line interfaces. Enter this type

of hunt rule on the Voice tab > SIP page > PBX Parameter section, Hunt Groups field.

• Line-Specific (Contact List) Hunt Rule: The hunt rule applies to a

particular line interface. Enter this type of hunt rule on the Voice tab > Line N page > Subscriber Information section > Contact List field. For example, if you enter this rule on the Line 1 page, it applies only to the calls that are received on Line 1.

The syntax for the two types of rules varies, as described later in this section. If you define a hunt group both in the Contact List and on the SIP page > PBX Parameters section, the call forward parameter from the Contact List is ignored; instead, the call forward parameter defined on the SIP page > PBX Parameter section is used.
