The LVS 9000 system uses the power of VoIP to provide enterprise-quality telephony features to small office/home office (SOHO) and small businesses. The LVS is based on open standards, such as SIP,. This allows interoperation with other standards-based products and simplifies configuration and use. The SPA9000, with a base license, supports up to four IP phones and up to 16 phones with an upgraded license.

With the optional SPA400, the SPA9000 can also manage calls to and from the PSTN. The SPA9000 also includes an Analog Telephone Adapter (ATA), with two FXS ports for connecting analog telephones, fax devices, or an external music source for the music on-hold service included with the SPA9000.

The SPA9000 supports four independent line interfaces with numbers assigned by one to four different ITSPs, with each line supporting up to 16 extensions. If the service provider supplies a group of sequential direct inward dial (DID) phone numbers (such as 408-777-1000 through 777-1015) the SPA9000 can support all the assigned numbers on a single line interface.

For information about LVS architecture, refer to the “SPA9000 Architecture” section on page 1-11.

SPA400 SIP-PSTN Gateway and Voicemail

The SPA400 is optionally used with the SPA9000 to provide a SIP-PSTN gateway, providing voice connectivity between the PSTN and local client stations connected to the SPA9000. It also provides a local voicemail server.

Note The SPA400 provides four FXO ports and occupies one line interface on the SPA9000.

A total of four SPA400 devices can be configured per SPA9000, using up to 16 analog phone lines and, with the SPA9000, automatically routing calls to and from your existing PSTN telephone service.

Chapter 1 Using the Linksys Voice System

Designed to be implemented with the SPA9000, the SPA400 lets cost-conscious business users take advantage of all the high-value features on the LVS, which are typically found on much more expensive voice communications systems. The SPA400 includes an integrated voicemail application supporting up to 32 voicemail accounts with customized greetings, providing LVS users the ability to receive and playback voicemail messages. The SPA400 ships with a USB voicemail module, which stores voicemail prompts and allows recording of up to four hours of high-quality voice messages.

For detailed information about using the SPA400 voice services and voicemail servers, refer to

Chapter 3, “Configuring Voice Service and Voicemail.”

Auto-Attendant

The Auto-Attendant is an internal service within the SPA9000. It plays pre-recorded voice messages that offer the caller a menu of choices, so the Auto-Attendant can appropriately direct the call. After the caller has made a choice, the call is routed to the appropriate extension. When the Auto-Attendant is enabled, it parses and operates on user input (key presses or DTMF tones) following the rules specified in the Auto-Attendant script on the SPA9000.

For detailed information about using and configuring the Auto-Attendant, refer to Chapter 5,

“Configuring the LVS Auto-Attendant.”

Session Initiation Protocol

The LVS is implemented using open standards, such as Session Initiation Protocol (SIP), allowing interoperation with all ITSPs supporting SIP. another subscriber in the network. In the SIP protocol, the requestor of the session is called the user agent server (UAS), while the receiver of the request is called the user agent client (UAC).

Note In this manual, the term client station is used to describe any SIP UA (including IP phones) that registers

with the SPA9000.

1-6

In a SIP VoIP network, when the SIP proxy receives a request from a client station (UAS) for a connection and it does not know the location of the UAC, it forwards the message to another SIP proxy in the network. Once the UAC is located and the response is routed back to the UAS, a direct peer-to-peer session is established between the two UAs. The actual voice traffic is transmitted between UAs over dynamically assigned ports using the Real-time Protocol (RTP).

Linksys SPA9000 Administrator Guide

Version 3.0

Page 21

Chapter 1 Using the Linksys Voice System

In Figure 1-3, UserA and UserB are client stations (UAs) that register over the local area network to which the SPA9000 PBX is connected. When UserA calls UserB, the SPA9000 acts as a SIP proxy and establishes a session between the two UAs. After the session is established, RTP traffic flows directly between the two client stations.

SIP Proxy

When a user picks up the handset in an LVS system, the SPA9000 collects DTMF digits from a touchtone analog telephone or the locally connected SPA900 Series IP phones. Unless the call is for a local client station, the SPA9000 system sends the full number in a SIP INVITE message to another SIP proxy server for further call processing.

To minimize dialing delay, a dial plan is maintained that is matched against the cumulative number entered by the user. Invalid phone numbers that are not compatible with the dial plan are detected and the user is alerted using a configurable tone (reorder) or announcement.

Figure 1-3 also illustrates connectivity between the SPA9000 and the ITSP over the Internet. 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. Again, once the session is established, RTP packets are exchanged directly between UserA and UserC. However, this requires that the firewall on the Internet routers allow UserA access to the Internet. Because the SIP UAs are generally assigned IP addresses dynamically through DHCP, this makes implementing a secure firewall policy more difficult.

SPA9000 Media Proxy

To address this possible security issue, the SPA9000 can also function as a media (RTP) proxy. This option forces RTP traffic destined for the Internet (or IP WAN) to be directed to the SPA9000, which then directs it to the remote UA. This configuration may simplify firewall configuration because the client stations do not require direct access to the Internet through the firewall.

To enable the media proxy, set the PBX Parameters:<Force Media Proxy> parameter to Tru e . With the media proxy enabled, when UserA calls User C, the SPA9000 still acts as the SIP proxy and forwards the request to the SIP server on the ITSP. However, even after the SIP session is established, the SPA9000 continues to direct RTP packets between UserA and the ITSP.

Version 3.0

Linksys SPA9000 Administrator Guide

1-7

Page 22

Technology Background

Local traffic is not affected by this configuration. When UserA initiates a call to UserB, RTP traffic still flows directly between the two UAs. The media proxy only affects RTP traffic to a UA connected through the ITSP.

Using the SPA9000 with a Firewall or Router

When using the SPA9000 behind a firewall or router, make sure that the following ports are not blocked:

• SIP ports—By default, UDP port 5060 and 5061

• RTP ports—16384 to 16482

Also disable SPI if this function exists on your firewall.

SPA400 SIP-PSTN Gateway

When a local user on the SPA9000 network initiates a call to a PSTN subscriber, the SPA400 acts as the SIP-PSTN gateway, which converts the SIP and RTP media packets into the appropriate signal for transmission to the PSTN switch. For example, if UserA calls UserD, the SIP request is routed by the SIP proxy in the SPA9000 to the SPA400. The SPA400 then converts the SIP and RTP packets it receives from UserA and the signals it receives from the PSTN switch.

Network Address Translation (NAT)

This section describes issues that arise when using the LVS on a network behind a network address translation (NA) device. It includes the following topics:

• NAT Overview, page 1-9

• NAT Types, page 1-10

• Simple Traversal of UDP Through NAT, page 1-10

• SIP-NAT Interoperation, page 1-11

NAT Overview

Network Address Translation (NAT) allows multiple devices to share the same public, routable, IP address for establishing connections over the Internet. NAT is typically performed by a router that forwards packets between the Internet and the internal, private network.

A typical application of a NAT is to allow all the devices in a subscriber home network to access the Internet through a router with a single public IP address assigned by an ISP. The IP header of the packets sent from the private network to the public network is substituted by NAT with the public IP address and a port assigned by the router. The receiver of the packets on the public network sees the packets as coming from the external address instead of the private address of the device.

Technology Background

The association between a private address and port and a public address and port is called a NAT mapping. This mapping is maintained for a short period of time, that varies from a few seconds to several minutes. The expiration time is extended whenever the mapping is used to send a packet from the source device.

Version 3.0

The ITSP may support NAT mapping using a Session Border Controller. This is the preferred option because it eliminates the need for managing NAT on the SPA9000. If this is not available, you will need to discuss with the ITSP how to use the NAT Support Parameters provided by the SPA9000, such as <Outbound Proxy> and <STUN Server Enable>.

Technology Background

NAT Types

Chapter 1 Using the Linksys Voice System

The different ways that NAT is implemented is sometimes divided into the following categories:

• Full cone NAT—Also known as one-to-one NAT. All requests from the same internal IP address and

port are mapped to the same external IP address and port. An external host can send a packet to the internal host, by sending a packet to the mapped external address

• Restricted cone NAT—All requests from the same internal IP address and port are mapped to the

same external IP address and port. Unlike a full cone NAT, an external host can send a packet to the internal host only if the internal host had previously sent a packet to it.

• Port restricted cone NAT/symmetric NAT—Port restricted cone NAT or symmetric NAT is like a

restricted cone NAT, but the restriction includes port numbers. Specifically, an external host can send a packet to a particular port on the internal host only if the internal host had previously sent a packet from that port to the external host.

With symmetric NAT all requests from the same internal IP address and port to a specific destination IP address and port are mapped to a unique external source IP address and port. If the same internal host sends a packet with the same source address and port to a different destination, a different mapping is used. Only an external host that receives a packet can send a UDP packet back to the internal host.

Simple Traversal of UDP Through NAT

Simple Traversal of UDP through NATs (STUN) is a protocol defined by RFC 3489, that allows a client behind a NAT device to find out its public address, the type of NAT it is behind, and the port associated on the Internet connection with a particular local port. This information is used to set up UDP communication between two hosts that are both behind NAT routers. Open source STUN software can be obtained at the following website:

http://www.voip-info.org/wiki-Open+Source+VOIP+Software

STUN does not work with a symmetric NAT router. To determine the type of NAT your router uses, complete the following steps:

Step 1 Enable debugging on the SPA9000:

1. Make sure you do not have firewall running on your PC that could block the syslog port (by default

this is 514).

2. On the administration web server, System tab, set <Debug Server> to the IP address and port number

of your syslog server.

Note that this address and port number has to be reachable from the SPA.

3. Set <Debug level> to 3 but you do not need to change the value of the <syslog server> parameter.

4. To capture SIP signaling messages, under the Line tab, set <SIP Debug Option> to Full. The output

is named syslog.514.log.

Step 2 To determine the type of NAT your router is using set <STUN Test Enable> to yes.

1-10

Step 3 View the syslog messages to determine if your network uses symmetric NAT or not.

Chapter 1 Using the Linksys Voice System

SIP-NAT Interoperation

In the case of SIP, the addresses where messages/data should be sent to a SPA9000 system are embedded in the SIP messages sent by the device. If the SPA9000 system is sitting behind a NAT device, the private IP address assigned to it is not usable for communications with the SIP entities outside the private network.

Note If the ITSP offers an outbound NAT-Aware proxy, this discovers the public IP address from the remote

endpoint and eliminates the need to modify the SIP message from the UAC.

The SPA9000 system must substitute the private IP address information with the proper external IP address/port in the mapping chosen by the underlying NAT to communicate with a particular public peer address/port. For this, the SPA9000 system needs to perform the following tasks:

• Discover the NAT mappings used to communicate with the peer.

This can be done with the help of an external device, such as a STUN server. A STUN server responds to a special NAT-Mapping-Discovery request by sending back a message to the source IP address/port of the request, where the message contains the source IP address/port of the original request. The SPA9000 system can send this request when it first attempts to communicate with a SIP entity over the Internet. It then stores the mapping discovery results returned by the server.

SPA9000 Architecture

• Communicate the NAT mapping information to the external SIP entities.

If the entity is a SIP Registrar, the information should be carried in the Contact header that overwrites the private address/port information. If the entity is another SIP UA when establishing a call, the information should be carried in the Contact header as well as in the SDP embedded in SIP message bodies. The VIA header in outbound SIP requests might also need to be substituted with the public address if the UAS relies on it to route back responses.

• Extend the discovered NAT mappings by sending keep-alive packets.

Because the mapping is alive only for a short period, the SPA9000 system continues to send periodic keep-alive packets through the mapping to extend its validity as necessary.

As shown in Figure 1-6, the SPA 9000 provides four logical line interfaces, referred to as Line 1, 2, 3, and 4. Each line can be configured with the same or a different ITSP. Each SPA400 also occupies one line interface. The SPA9000 has five internal clients that register implicitly with the internal SIP proxy:

• FXS1 (fxs1)

• FXS2 (fxs2)

• Call Park (callpark)

• Auto-Attendant (aa)

• Internal Music Server (imusic)

The Setup Wizard is a convenient way to perform initial configuration for the SPA9000. It provides step-by-step guidance for configuring the basic operation of voice services, voicemail, and most of the main features provided by the SPA9000.

The Setup Wizard overwrites any existing configuration information that has been entered through the administration web server, so it should not be used for ongoing administration and configuration unless it provides adequate functionality for you to use it exclusively. You can, however, use the Setup Wizard for initial configuration and then use the administration web server for ongoing configuration and maintenance.

You can download the latest Setup Wizard from the following website:

http://www.linksys.com/

To start the Wizard, just double-click on the executable file. For information about getting started with the Setup Wizard, refer to the

Administration Web Server

The administration web server provides a series of web pages that let you enter detailed configuration information for the many features and options provided by the SPA9000. It also lets you monitor the status of the attached client stations.

The administration server provides a basic and an advanced view from which the various configuration parameters can be accessed. The Provisioning tab is only visible from the advanced Administrator account view of the web interface.

“Using the Wizard for Initial Configuration” section on page 2-14

Administration Web Server” section on page 2-23. For a description of each parameter provided by the

administration web server, refer to Chapter 6, “SPA9000 Field Reference”

Local Client Configuration and Registration

SPA9000 provides a TFTP server to assign configuration information to the locally attached client stations. When the SPA9000 receives a request for /cfg/init_$MA.xml, it automatically assigns the next available user id (extension number) to the client station. The initial user ID is configured using the PBX Phone Parameters:<Next Auto User ID> parameter and is automatically incremented each time a new number is assigned. Before assigning a new user ID, the SPA9000 also checks if there is any registered client station using that ID and increases the ID until an unused value is found.

Remote Provisioning of the SPA9000

The SPA9000 provides for secure provisioning and remote upgrade. Provisioning is achieved through configuration profiles transferred to the device via TFTP, HTTP, or HTTPS. User intervention is not required to initiate or complete a profile update or firmware upgrade.

The SPA9000 can be configured to automatically resync its internal configuration state to a remote profile periodically and during power up. The automatic resync is controlled by configuring the profile URL for the device.

The SPA9000 accepts profiles in XML format, or alternatively in a proprietary binary format, which can be generated by a profile compiler tool available to qualified VoIP vendors and partners from Linksys. The SPA9000 supports up to 256-bit symmetric key encryption of profiles. For the initial transfer of the profile encryption key (initial provisioning stage), the SPA9000 can receive a profile from an encrypted channel (HTTPS with client authentication), or it can resync to a binary profile generated by the Linksys-supplied profile compiler. In the latter case, the profile compiler can encrypt the profile specifically for the target SPA9000, without requiring an explicit key exchange.

SPA9000 Architecture

Remote firmware upgrade is achieved via TFTP or HTTP (firmware upgrades using HTTPS are not supported). Remote upgrades are controlled by configuring the desired firmware image URL into the SPA9000 via a remote profile resync.

For further information about remote provisioning refer to the LVS SPA Provisioning Guide.

The following are the basic hardware requirements to implement an LVS PBX system:

• SPA9000

• One or more SPA900 series IP Phones (as client stations)

• Ethernet network cables

• One or more Ethernet switches with QoS support and with the required number of available ports

• A PC for configuration of the SPA9000 and other client stations on the network. This can be

connected to the switch or directly to the Ethernet port on the SPA922, 942, or 962 IP phone.

The following components can optionally be added to provide additional functionality:

2-2

• FAX machine to send or receive faxes

• A router with QoS support, and a broadband (cable/DSL) modem (gateway) with connectivity to an

ISP

• SPA400 SIP-PSTN gateway for connectivity to the PSTN and local voicemail service

• PSTN DID lines

For best results, use a router and switch that both support Quality of Service (QoS). QoS allows top priority to be assigned to voice traffic. Otherwise, the quality of the voice connection may suffer when large files are moved over the network.

Note The SPA9000, the SPA400, and the SPA900 Series IP phones should all be within the same LAN.

Separating the devices through VPN encryption, firewalls, routers, or other devices that affect multicast traffic may prevent proper functioning of the IP PBX system.

Linksys SPA9000 Administrator Guide

Chapter 2 Getting Started

\In addition, you need at least one active ITSP phone service account and its settings (including DID number for incoming calls) if you use the Internet for telephone service. If you are using the SPA400 for connection to the PSTN, you need at least one active PSTN line.

The LVS can also be implemented with hosted voicemail services provided by the ITSP. In this scenario, the SPA-400 is not configured for voicemail, but is only used for as a SIP-PSTN gateway, providing telephone connectivity to PSTN subscribers.

Note For first-time installation of the SPA9000, it is recommended that you use the SPA9000 Setup Wizard,

which you can download from www.linksys.com. For further information, see

Initial Configuration” section on page 2-14.

Using the SPA9000 as a Media Proxy

The SPA9000 can as a media proxy, which means that all RTP traffic between local client stations and client stations on the Internet are routed through the SPA9000. This simplifies firewall configuration because only the SPA9000 requires access to the Internet through the firewall.

Implementing LVS

“Using the Wizard for

By default, the SPA9000 acts only as a SIP proxy. This means that once a SIP connection is established, further communication between the SIP UAs occurs directly. To enable the SPA9000 as a media proxy, set the PBX Parameters:<Force Media Proxy> parameter to yes.

Using the LVS as a Key System

An easy and cost-effective way to implement the SPA9000 is as a replacement of a legacy key system, in which a single DID line from the PSTN supports a single extension. In a key system all lines appear as shared lines. This allows a user to pick up a ringing line from any phone in the key system (see

Figure 2-2).

Up to 4 DID lines per SPA400

Shared line appearance

When implementing the SPA9000 and SPA400 as a key system, the SPA9000 is connected through a switch to one or more SPA400s, which are then connected to the existing DID lines from the PSTN. The SPA9000 has four line interfaces, each of which can support one SPA400 or a single VoIP account with an ITSP. A single VoIP account with an ITSP can map to multiple DID numbers assigned by the ITSP.

Each SPA400 can support up to four DID lines assigned by the PSTN, so with a SPA400 connected to all four line interfaces, the SPA9000 can support up to 16 DID lines to the PSTN.

Bandwidth Requirements

Depending on how you have your IP phones configured, each call requires 55 to 110 kbps in each direction. Therefore, using G.729 as the voice codec setting, and with an average business-grade broadband Internet connection supporting 1.5 Mbps downstream and 384 kbps upstream, a total of seven (7) simultaneous conversations can be reliably supported with adequate bandwidth available for file downloads.

Initial Setup and Configuration

This section describes how to complete the initial connection and configuration of the SPA9000 system. It includes the following topics:

• Licensing, page 2-13

• Using DHCP or Static IP Addressing, page 2-13

• Using the Wizard for Initial Configuration, page 2-14

• Using the Wizard to Upgrade Software, page 2-19

Licensing

The SPA9000 is shipped from the factory with a four-user license. This means that the SPA9000 allows registration from up to four external IP addresses (first come/first serve). If you need to support more client stations, you can purchase a 16-user license and install it by entering the license key using the <License Keys> parameter on the Provisioning page. To obtain a license, contact sipura-sales@cisco.com.

Using DHCP or Static IP Addressing

Before running the Setup Wizard, you need to decide if you are using DHCP or static IP addressing. Static IP addressing is recommended for the SPA400. The SPA900 series phones typically obtain their addresses through the DHCP server on the broadband router that connects to the broadband modem. The SPA9000 can either be assigned a static address if this has been provided by your ISP, or it can be assigned a dynamic IP address by the DHCP server on your router or by the ISP.

Administrator Account Privileges

The SPA9000 supports two levels of administration privileges: Administrator and User. Both privileges can be password protected.

Note By default, there are no passwords assigned for either the Administrator account or the User account.

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. The User account only has the privilege to access part of the web profile parameters. The parameters that the User account can access are specified on the Provisioning page of the administration web server.

To directly access the Administrator account level privilege, use the following URL:

http://spa_9000_ipaddress/admin/voice

If the password has been set for the Administrator account, the browser prompts for authentication. The User account name and the Administrator account name cannot be changed.

Using the Administration Web Server

When browsing pages with the Administrator account privilege, you can switch to User account privilege by clicking the User Login link.

If the User account password is set, the browser prompts for authentication when you click the User Login link). From the User account, you can switch to the Administrator account by clicking the Admin Login link. Authentication is required if the Administrator account password has been set.

Note Switching between User and Administrator accounts or between basic and advanced views discards any

uncommitted changes that have already been made on the web pages.

Advanced Methods of Configuration

This section describes some advanced methods of configuration that you may find useful if you are administering a large number of SPA9000 devices. This section includes the following topics:

• Web Interface URLs, page 2-26

• Provisioning, page 2-27

• Client Auto-Configuration, page 2-29

• Manual Client Configuration, page 2-30

Web Interface URLs

The SPA9000 web interface supports several functions through special URLs:

• Upgrade

• Reboot

• Resync

Chapter 2 Getting Started

Upgrade URL

Note If the value of the <Upgrade Enable> parameter in the Provisioning page is No, you cannot upgrade the

Administrator account privilege is needed for these functions.

The Upgrade URL lets you upgrade the SPA9000 to the firmware specified by the URL, which can identify either a TFTP or HTTP server.

SPA9000 even if the web page indicates otherwise.

The syntax of the Upgrade URL is as follows:

• http://spa-ip-addr/admin/upgrade?[protocol://][server-name[:port]][/firmware-pathname]

Both HTTP and TFTP are supported for the upgrade operation.

If no protocol is specified, TFTP is assumed. If no server-name is specified, the host that requests the URL is used as server-name.

If no port specified, the default port of the protocol is used. (69 for TFTP or 80 for HTTP)

The firmware-pathname is typically the file name of the binary located in a directory on the TFTP or HTTP server. If no firmware-pathname is specified, /spa.bin is assumed, as in the following example:

http://192.168.2.217/admin/upgrade?tftp://192.168.2.251/spa.bin

Resync URL

2-26

The Resync URL lets you force the SPA9000 to do a resync to a profile specified in the URL, which can identify either a TFTP, HTTP, or HTTPS server.

Linksys SPA9000 Administrator Guide

Version 3.0

Page 57

Chapter 2 Getting Started

Note The SPA resyncs only when it is idle.

Reboot URL

Advanced Methods of Configuration

The syntax of the Resync URL is as follows:

http://spa-ip-addr/admin/resync?[[protocol://][server-name[:port]]/profile-pathname]

If no parameter follows /resync?, the Profile Rule setting from the Provisioning page is used.

If no protocol is specified, TFTP is assumed. If no server-name is specified, the host that requests the URL is used as server-name.

If no port is specified, the default port is used (69 for TFTP, 80 for HTTP, and 443 for HTTPS).

The profile-path is the path to the new profile with which to resync, for example:

http://192.168.2.217admin/resync?tftp://192.168.2.251/spaconf.cfg

The Reboot URL lets you reboot the SPA9000.

Note The SPA9000 reboots only when it is idle.

The Reboot URL is http://spa-ip-addr/admin/reboot.

Provisioning

This section describes the provisioning functionality of the SPA9000. This section includes the following topics:

• Provisioning Capabilities, page 2-27

• Configuration Profile, page 2-28

For detailed information about provisioning the SPA9000, refer to the LVS SPA Provisioning Guide.

Provisioning Capabilities

The SPA9000 provides for secure provisioning and remote upgrade. Provisioning is achieved through configuration profiles transferred to the device via TFTP, HTTP, or HTTPS.

The SPA9000 can be configured to automatically resync its internal configuration state to a remote profile periodically and on power up. The automatic resyncs are controlled by configuring the desired profile URL into the device.

Version 3.0

The SPA9000 accepts profiles in XML format, or alternatively in a proprietary binary format, which is generated by a profile compiler tool available from Linksys. The

SPA9000 supports up

to 256-bit symmetric key encryption of profiles. For the initial transfer of the profile encryption key (initial provisioning stage), the

SPA9000 can receive a profile from an encrypted channel

Advanced Methods of Configuration

(HTTPS with client authentication), or it can resync to a binary profile generated by the Linksys-supplied profile compiler. In the latter case, the profile compiler can encrypt the profile specifically for the target

Remote firmware upgrade is achieved via TFTP or HTTP (firmware upgrades using HTTPS are not supported). Remote upgrades are controlled by configuring the desired firmware image URL into the

For further information about remote provisioning refer to the LVS SPA Provisioning Guide. For further information about certificate generation for use with an HTTPS server, contact sipura-sales@cisco.com.

Configuration Profile

The SPA9000 configuration profile can be either an XML file or a binary file with a proprietary format.

The XML file consists of a series of elements (one per configuration parameter), encapsulated within the element tags <flat-profile> … </flat-profile>. The encapsulated elements specify values for individual parameters. Here is an example of a valid XML profile:

Chapter 2 Getting Started

SPA9000, without requiring an explicit key exchange.

SPA9000 via a remote profile resync.

<flat-profile> <Admin_Passwd>some secret</Admin_Passwd> <Upgrade_Enable>Yes</Upgrade_Enable> </flat-profile>

Binary format profiles contain SPA9000 parameter values and user access permissions for the parameters. By convention, the profile uses the extension .cfg (for example, spa2000.cfg). The Linksys Profile Compiler (SPC) tool compiles a plain-text file containing parameter-value pairs into a properly formatted and encrypted .cfg file. The SPC tool is available from Linksys for the Win32 environment and Linux-i386-elf environment. Requests for SPC tools compiled on other platforms are evaluated on a case-by-case basis. Please contact your Linksys sales representative for further information about obtaining the SPC tool.

The syntax of the plain-text file accepted by the profile compiler is a series of parameter-value pairs, with the value in double quotes. Each parameter-value pair is followed by a semicolon. Here is an example of a valid text source profile for input to the SPC tool:

Admin_Passwd “some secret”; Upgrade_Enable “Yes”;

Refer to the LVS SPA Provisioning Guide for further details.

The names of parameters in XML profiles can generally be inferred from the SPA9000 configuration Web pages, by substituting underscores (_) for spaces and other control characters. Further, to distinguish between Lines 1, 2, 3, and 4, corresponding parameter names are augmented by the strings _1_, _2_, _3_, and _4_. For example, Line 1 Proxy is named Proxy_1_ in XML profiles.

Parameters in the case of source text files for the SPC tool are similarly named, except that to differentiate Line 1, 2, 3, and 4, the appended strings ([1], [2], [3], or [4]) are used. For example, the Line 1 Proxy is named Proxy[1] in source text profiles for input to the SPC.

Client Auto-Configuration

An unprovisioned client station in the factory default state can be automatically provisioned by the SPA9000 by following the flow chart shown in

When the SPA9000 receives a request for /cfg/init_$MA.xml, it automatically assigns the next available user ID (extension number) to this client station. The next user ID to be assigned to a new client station is configured using The <Next Auto User ID> parameter and is automatically incremented each time a new number is assigned. Before assigning a new user ID, the SPA9000 also checks whether there is any registered client station using that ID and keeps increasing the ID until an unused value is found.

Client stations download spa$PSN.cfg and init_$MA.xml only once for initial configuration. However, they download generic.xml on every reboot. Therefore, parameters manually configured on the client station that overlap with the contents of generic.xml are overwritten with the SPA9000-supplied values. The list of parameters included in generic.xml are thus purposely kept to a very small set.

Client Registration

All client stations served by the SPA9000 must register to the SPA9000, which does not allow a station to make calls unless it is registered. If the client station is configured with Station Name, it should include a P-STATION-NAME header in the REGISTER request. Following is an example where User-A has been assigned a primary extension of 5031.

REGISTER sip:192.168.0.1:6060 SIP/2.0 Via: SIP/2.0/UDP 192.168.0.4:5060;branch=z9hG4bK-8865c41e From: “User-A” <sip:5031@192.168.0.1:6060>;tag=a76a3e1dfc6045cdo0 To: “User-A” <sip:5031@192.168.0.1:6060> Call-ID: 52dab65d-21d02a8d@192.168.0.4 CSeq: 1 REGISTER Max-Forwards: 70 Contact: “User-A” <sip:5031@192.168.0.4:5060>;expires=3600 User-Agent: Sipura/SPA841-3.1.4(a0714sec) P-Station-Name: User-A Content-Length: 0 Allow: ACK, BYE, CANCEL, INFO, INVITE, NOTIFY, OPTIONS, REFER, SUBSCRIBE Allow-Events: dialog

In this example, User-A shares a line appearance with User-B, whose primary extension is

5041. Extension 2 on the User-A station must then be set up the same way as Extension 1 (User-A primary extension), but with the <Shared User ID> parameter set to 5041. The User-A station then performs a third-party registration for Extension 2, as shown below. Note that the TO header <user-id> parameter is the User-B primary extension.

The 200 reply sent by the SPA9000 to the client station REGISTER request includes a DATE header that the client station can use to synchronize with its local real-time clock. The time served in the DATE header is the local time (as opposed to GMT). There is thus no need to configure an NTP server or a time zone on the client stations. This assumes that the SPA9000 can maintain the real-time clock based on an NTP server or a DATE header supplied by the ITSP. Following is an example of a 200 response to REGISTER (note that there is no weekday in the DATE header):

A. Click File. Make sure Work Offline is NOT checked. B. Press CTRL + F5. This is a hard refresh, which forces Windows Explorer to load new webpages, not

cached ones.

C. Click Tools. Click Internet Options. Click the Security tab. Click the Default level button. Make

sure the security level is Medium or lower. Then click the OK button.

9. How do I save my current SPA configuration?

Currently, the only way is to do HTTPGET from an HTTP client, from which you get the entire HTML page. Alternatively, from your browser you can select File > Save as > HTML from any of the administration web server pages. Do this in Admin, Advanced mode. This saves all the tabs into one HTML file. This HTML file is helpful to provide to our support team when you have a problem or technical question.

10.How do I debug my SPA? Is there a syslog?

SPA sends out debug information via syslog to a syslog server. The ports can be configured (by default the port is 514).

A. Make sure you do not have firewall running on your PC that could block port 514. B. On the administration web server System tab, set <Debug Server> as the IP address and port

number of your syslog server. Note that this address has to be reachable from the SPA9000).

C. Also, set <Debug level> to 3.

You do not need to change the value of the <syslog server> parameter.

D. To capture SIP signaling messages, under the Line tab, set <SIP Debug Option> to Full.

The file output is syslog.<portnum>.log (for the default port setting, syslog.514.log)

11. How do I view the status of my VoIP devices when I can’t access the administration web server on

the network?

A. Connect a regular Ethernet cable to the Ethernet (LAN) port of the SPA9000.

Note The Ethernet port on the SPA9000 is not intended for use to connect the device to the

network.

B. Direct your web browser to the following URL:

http://192.168.0.1/admin/router/status

C. If you do not get a response, ping the interface to verify that it is working, or use IVR option

#210 to verify the address on the LAN interface.

D. Click PBX Status on the Line tab.

12.How do I access the SPA9000 if I forget my password?

By default, the Admin account has no password. If a password is set for this account and you do not know what it is, you have to reset the device to its factory defaults. There are two options for resetting the device:

Option 877778 resets the unit to the configuration shipped from the ITSP and erases any configuration completed locally by the user.

Option 73738 resets the unit to the configuration shipped by Linksys and erases local configuration any provisioning configured by the ITSP.

To reset the SPA9000 to the factory defaults, perform the following steps:

Version 3.0

A. Connect an analog phone to the SPA9000 and access the IVR by pressing ****. B. Press 877778# to reset the unit to the defaults as it shipped from the ITSP or press 73738# to reset the

unit to the defaults as it shipped from Linksys.

C. Press 1 to confirm the operation. Press * to cancel the operation. D. Login to the unit using the Admin account without a password and reconfigure the unit.

13. My SPA9000 is behind a NAT device or firewall and I’m unable to make a call or I’m only receiving a one-way connection. What should I do?

A. Configure your router to port forward “TCP port 80" to the ip address currently being used by

SPA. If you do this often, we suggest that you use static IP address for the SPA, instead of DHCP. (For help with port forwarding, consult your router documentation)

B. On the Line tab of the administration web server, change the value of <Nat Mapping Enable> to

yes. On the SIP tab; change <Substitute VIA Addr> to yes, and <EXT IP> to the IP address of your router.

C. Make sure you are not blocking the UDP PORT 5060,5061 and port for UDP packets in the

range of 16384-16482. Also, disable “SPI” if this feature is provided by your firewall. Identify the SIP server to which the SPA9000 is registering, if it supports NAT, using the <Outbound

Proxy> parameter. D. Adjust the NAT keepalive variables as follows: E. Check the following settings on the administration web server: F. Add a STUN server to allow traversal of UDP packets through the NAT device. On the SIP tab of the

administration web server, set <STUN Enable> to yes, and enter the IP address of the STUN server

in <STUN Server>.

STUN (Simple Traversal of UDP through NATs) is a protocol defined by RFC 3489, that allows a

client behind a NAT device to find out its public address, the type of NAT it is behind, and the port

associated on the Internet connection with a particular local port. This information is used to set up

UDP communication between two hosts that are both behind NAT routers. Open source STUN

software can be obtained at the following website:

http://www.voip-info.org/wiki-Open+Source+VOIP+Software

Chapter 2 Getting Started

Note STUN does not work with a symmetric NAT router. Enable debug through syslog (see FAQ#10),

and set <STUN Test Enable> to yes. The messages indicate whether you have symmetric NAT or not.

14. I manually entered the proxy address into my SPA941 but it doesn't register with the SPA9000. A. Make sure to have the SPA9000 IP address and the corresponding port, the default port is 6060 <

Proxy Listen Port>. For example, enter 192.168.0.1:6060 in the Proxy location of the SPA941.

15. Why can’t I register the FXS ports to an outside proxy?

A. The FXS ports are registered directly with the SPA9000; no options exists for it to connect to

another proxy.

16. Why does the SPA941 reboot when rebooting the SPA9000? A. When booting, the SPA9000 sends a multicast message to request all client stations to gracefully

reboot. This allows the client stations to redo DHCP discovery, download latest phone parameters, and also register with the SPA9000.

17.Why do only four SPA900 Series clients register?

A. The SPA9000 ships with a four-user license. To support more clients, purchase a 16-user license

and install it by entering the license key in the < License Key> parameter on the Provisioning page of the web server administration server. To obtain a license key contact sipura-sales@cisco.com.

Note When using the Setup Wizard to configure the SPA400, disable other network cards on the PC where

you are running the Setup Wizard except for the card that is connected to the SPA9000 through the local switch. Otherwise, the Setup Wizard may fail to properly locate the SPA400.

Understanding How the SPA400 Interacts with the SPA9000

The SPA400 features the ability to connect up to four standard analog telephones lines to a Linksys Voice SPA9000 (LVS) VoIP network and includes the additional benefit of a voicemail application. A total of four SPA400 devices can be configured per SPA9000, using up to 16 analog phone lines and automatically routing calls to and from your existing PSTN telephone service.

Use the SPA400 for access to the PSTN by connecting its FXO ports to analog lines provisioned by the local carrier. There are specific Line settings on the SPA9000 that are configured to recognize a SPA400 as a service enabling calls from an IP phone on a LVS network to be routed to the PSTN and vice versa. The SPA400 sets up and tears down calls between the PSTN and IP phones, offering seamless telephone service with Linksys VoIP equipment.

Using the SPA9000 Setup Wizard to Configure the SPA400

It is recommended that you use the SPA9000 Setup Wizard to install and configure the SPA400. Version

1.1.0.3 (or higher) of the SPA9000 Setup Wizard supports the SPA400 for the initial or an existing LVS

installation. Connect the SPA400 to the network using its Ethernet port before running the SPA9000 Setup Wizard. The latest version of the SPA9000 Setup Wizard can be downloaded from

http://www.linksys.com.

Accessing the Administration Web Server

The SPA400 and the SPA9000 have corresponding parameters that must be properly configured for a successful installation. If you do not use SPA9000 Setup Wizard, you can complete the configuration using the administration web server provided by each device.

Note If you use the Setup Wizard to configure the SPA400 after using the administration web server, you may

lose any changes to the SPA9000 factory default configuration made with the administration server.

To access the SPA400 administration web server, direct your browser to the IP address of the SPA400.

Running the SPA9000 Setup Wizard simplifies installation and automatically detects the IP address of the SPA400. If you are using DHCP, to determine the IP address of the SPA400, view the DHCP clients table for the DHCP server that assigned the address to the SPA400.

After entering the IP address of the SPA400 into the browser, a password request page appears. The administrator account name for the SPA400 is Admin (with a capital A) and with the default configuration, the password field should be left blank (no password). Click the OK button to access the SPA400 administration web server.

Chapter 3 Configuring Voice Service and Voicemail

Note Requiring a password to access the SPA400 prevents unauthorized changes to the settings of the device.

To assign a password, select the Administration tab on the administration web server and then click Management.

Configuring the SPA400 to Connect to the SPA9000

The following steps demonstrate how to configure a SPA400 on an LVS network with a SPA9000. The example configuration assumes that a SPA9000 is configured to access the PSTN only, and therefore the SPA400 is configured in the Line 1 tab on the SPA9000. If a VoIP service provider is also defined, a SPA400 can be configured in any of the available Line tabs (1–4) on the SPA9000 administration web server.

Step 1 From the SPA400 administration web server, click SPA9000 Interface on the Setup tab.

Step 2 Enter the user ID of the SPA9000 in the User ID field.

The User ID setting must be identical to the User ID configured in the associated field in the Line # field on the SPA9000.

The Discover Automatically radio button enables the SPA400 to learn the IP address and the UDP port of the SPA9000 from the SIP registration packets sent by the SPA9000.

Note A static IP address is recommended for the SPA400, but the SPA9000 may be assigned its IP

address by the DHCP server on the local router or directly from the ISP over the WAN link.

3-12

Step 3 If you are using a static IP address for the SPA9000, enter this address and the UDP port to enable the

SPA400 to listen for the SIP registration request from the SPA9000.

If the SPA9000 obtains an IP address from a DHCP server, leave the Discover Automatically option enabled to avoid registration failure because of a possible change in the SPA9000 IP address or expiration of the DHCP lease.

Configuring the SPA9000 to Register the SPA400

This section describes how to configure three settings on the SPA9000 that are required to register the SPA400 with the SPA9000.

Step 1 Select the appropriate Line tab from the SPA9000 administration web server .

Step 2 On the Line page for the line assigned to the SPA400, make sure the following fields match the settings

entered in the SPA400 configuration:

• SIP settings—SIP port = 5060

This is the default SIP port. Only change this value if a different port is configured on the SPA400 for some reason.

• Subscriber information—User ID = SPA400_User_ID

Replace SPA400_User_ID with the value entered on the User ID field of the SPA9000 Interface on the Setup tab of the SPA400 In the example, this value is SPA9000.

• Proxy and registration—Proxy = SPA400 IP Address

Replace SPA400_IP_Address with the actual IP address of the SPA400. In the example, this is

192.168.1.103.

Step 3 Click the Submit All Changes button on the SPA9000 administration web server.

The SPA9000 device reboots.

Configuring the SPA400 for PSTN Connectivity or Voicemail

The SPA9000 is now configured to access the PSTN through the SPA400.

Configuring the SPA400 Voicemail Services

The SPA400 includes a USB voicemail module for users (or extensions) configured on a SPA9000. The USB flash drive that ships with the SPA400 provides a total of 128 MB of storage for voicemail prompts and mailbox messages. The maximum length of an individual message is 180 seconds <<or maybe 60 seconeds; Nelson is testing this>>. Mailbox messages require 480KB per minute of recording time, so the flash disk can contain a total of more than 3 hours of mailbox messages.

When you receive the SPA400, you can back up the voicemail prompts and other files on the USB drive to a secure location on a PC or server on your network. You can then copy these files to a larger compatible USB drive, in case you need more voicemail storage. To determine if a USB drive is compatible, after copying the files to it, insert it into the USB port on the SPA400. View the status of the <<>> parameter on the SPA400 administration web server.

The integrated voicemail application server supports 32 configurable voicemail accounts enabling users to leave and play back voice messages. (Although a SPA9000 can be configured with up to 4 SPA400 devices, only 1 SPA400 can be configured with the voicemail application).

The SPA9000 can be configured with up to four SPA400 devices, the voice mail service can either concentrate with one SPA400 or distribute among the four SPA400. However, an IP Phone can only subscribe to one mailbox from one SPA400..

To configure the SPA400 to register with the SPA9000, complete the following steps.

Version 3.0

Step 1 From the SPA400 administration web server, click Voicemail Server on the Setup tab (see Figure 3-17).

Step 2 In the Server Port field, enter the UDP port over which the Voicemail Server listens for signaling

between the SPA400 and the SPA9000.

In Figure 3-17, the value of this field is 5090.

Chapter 3 Configuring Voice Service and Voicemail

Note This port number must be different from the UDP port configured in the SPA9000 Interface

menu.

Step 3 Enter the User ID that the SPA9000 uses to register the SPA400 voicemail server.

This setting must be identical to the User ID configured in the SPA400 SPA9000 Interface page. In the example, this value is SPA9000.

Step 4 In the SPA9000 subscriber ID field, enter the Subscriber ID that the SPA9000 uses to subscribe to the

SPA400 voicemail server for obtaining notification.

Step 5 In the Mailbox deposit number field, enter the associated telephone number that the SPA9000 uses to

deposit voicemail.

Step 6 In the Mailbox manage number field, enter the associated telephone number that the SPA9000 uses to

access voicemail.

Step 7 Click Save Settings at the bottom of the page and then the Restart button on the SPA400 administration

web server.

The SPA400 device reboots.

Configuring the SPA9000 Voicemail Settings

You must match the parameters entered in the SPA400 Voicemail Server fields in the SPA9000 administration web server under the associated Line # used for the SPA400 voicemail server.

The example assumes the SPA9000 is configured to use Line 1. The configuration and installation of the SPA400 and the integrated voicemail application server can be configured on the same SPA9000 Line tab.

Chapter 3 Configuring Voice Service and Voicemail

Managing Voicemail

On the SPA9000, accessing a voicemail server to check or deposit voicemail is similar to calling an external number, or being call forwarded to an external number. Each line interface can use a different voicemail server.

Linksys SPA9000 Administrator Guide

3-20

Version 3.0

Page 87

Chapter 3 Configuring Voice Service and Voicemail

There are three groups of voicemail operations:

• Depositing voicemail

• Managing voicemail from a client station or from an external number

• Subscription to voicemail notification and receiving voicemail notification

SPA9000 assumes that a voicemail account can include more than one mailbox ID (MBID). The voicemail account is defined with a user-ID, which can be the same as the line interface user-ID.

Three parameters must be configured on the SPA9000 for each line to support these operations: <Mailbox Deposit URL>, <Mailbox Manager URL>, and <Mailbox Subscribe URL>.

Note The mailbox ID should be set to the extension number.

Voicemail service may be offered by a service provider different from the ITSP. For example, you can configure Line 1, 2, and 3 with accounts on an ITSP, but configure Line 4 an account with a different Internet voicemail service provider (IVMSP). The SPA9000 can be configured to bridge calls between the ITSP and the IVMSP when necessary (when depositing or checking voicemail by an external caller) using the <VMSP Bridge> parameter on each line interface.

Managing Voicemail

How Voicemail Works

When a user checks voicemail from a client station, the SPA9000 sends an INVITE on its behalf to the configured <Mailbox Manage URL>. For example:

INVITE sip:mailbox-manage-url SIP/2.0 Via: SIP/2.0/UDP 192.168.2.205:5060;branch=z9hG4bK-171eb6b5 From: <sip:37683102@sip.myitsp.com>;tag=300704dd2590d20bo2;ref=5031;mbid=53371 To: <sip:mailbox-manage-url> Call-ID: 58a2b2c5-66e2bd43@192.168.2.205 CSeq: 101 INVITE Max-Forwards: 70 Contact: <sip:37683102@192.168.2.205:5060> Ö

Here the client station is at extension 5031 and the mailbox ID is 53371. The voicemail server should then prompt the caller to enter a PIN and access the voicemail features for the given mailbox.

A user should also be able to call an external number explicitly from anywhere to retrieve voicemails. When the voicemail server receives such a call, it should prompt the caller to enter the mailbox ID and then the PIN number. If the user-ID of the voicemail account cannot be uniquely identified from the mailbox ID or from the called number, the server must first prompt the user to enter the user-ID before proceeding.

Note If an EXT-To-DID mapping exists for the calling extension on the line interface, the user-ID and display

name fields of the FROM header are replaced by the mapped DID number and the display name assigned to the phone, respectively. In this case, a DIVERSION header similar to the REFERRED-BY header is also included.

Version 3.0

Linksys SPA9000 Administrator Guide

Managing Voicemail

Checking Voicemail from an External Number

The Internet voicemail service provider (IVMSP) may have an external number for their subscribers to call to check/manage their mailboxes. If this is not available, you may do one of the following:

• (a) assign a DID number (from the ITSP)

• (b) create a virtual extension for this purpose.

For method (a), specify a rule in the <Contact List> for the dedicated DID number. For the DID number 18005551000, this would look like the following example:

...|...|18005551000:vmm3|...

The syntax vmm<n> tells the SPA9000 to forward calls dialed to 18005551000 to the voicemail management URL on Line <n>. Because no particular mailbox is specified in this example, the caller is prompted to enter the voicemail number after the voicemail server answers. You may also specify a particular mailbox ID with this syntax (for example, vmm31234).

Method (b) is used in conjunction with the Auto-Attendant. For example, you can define a single-digit extension 7 to map to the voicemail management URL on Line 4, by adding a rule to <AA Dial Plan 1> or <AA Dial Plan 2> depending on which one you are using. The rule would look like the following:

<7:vmm4>

Chapter 3 Configuring Voice Service and Voicemail

Again, you may also specify a particular mailbox in this syntax. For information about configuring the Auto-Attendant, refer to

Depositing Voicemail

An external caller can be triggered to deposit voicemail into a mailbox by sending it a REFER request during a call with <Mailbox Deposit URL> indicated in the REFER-TO header and the mailbox ID in the REFERRED-BY header. The caller device then sends INVITE to the <Mailbox Deposit URL> as shown in the example below:

INVITE sip:mailbox-deposit-url SIP/2.0

Via: SIP/2.0/UDP 24.35.36.111;branch=z9hG4bK-29752ae9

From: “External Caller” <sip:9991234@sip.myitsp.com>;tag=b99e21414928473o2

To: <sip:mailbox-deposit-url>

Call-ID: 69e9e3d9-cfcbe2bb@24.35.36.111

CSeq: 101 INVITE

Contact: <sip:9991234@24.35.36.111>

Referred-By: <sip:37683101@sip.myitsp.com>;ref=5041;mbid=7675

In the last example, the caller is directed to deposit voicemail in the mailbox ID 7675 on the voicemail account 37683101. It further indicates that the directing station is at the internal extension 5041. Note that it is assumed that the caller device (or the ITSP) is faithfully relayed over the REFERRED-BY header.

Chapter 5, “Configuring the LVS Auto-Attendant.”

3-22

Note The mailbox ID must be set to the extension number.

The INVITE sent for an internal caller to deposit voicemail is similar, except that the FROM header also includes a reference parameter, as shown in the following example:

INVITE sip:mailbox-deposit-url SIP/2.0

Via: SIP/2.0/UDP 172.12.244.56;branch=z9hG4bK-29752ae9

From: Line 1 <sip:37683101@sip.myitsp.com>;tag=b99e21414928473o2;ref=5031

Linksys SPA9000 Administrator Guide

Version 3.0

Page 89

Chapter 3 Configuring Voice Service and Voicemail

To: <sip:mailbox-deposit-url> Call-ID: 69e9e3d9-cfcbe2bb@172.12.244.56 CSeq: 101 INVITE Max-Forwards: 70 Contact: <sip:37683101@172.12.244.56> Referred-By: <sip:37683101@sip.myitsp.com>;mbid=7675

In the above example, the station wanting to deposit voicemail is at extension 5031; the mailbox ID is 7675 on the account 37683101 (for the station at extension 5041). Note that the referrer is the same as the caller in the last INVITE. In other words, this INVITE is self-triggered by the SPA9000.

If an EXT-To-DID mapping exists for the calling extension on the line interface, the user-ID and display name fields of the FROM header is replaced by, respectively, the mapped DID number and the display name assigned to the phone. Furthermore, if an EXT-To-DID mapping exists for the called phone, the user-ID field of the REFERRED-BY header is also replaced by the mapped DID number for the called extension.

Note For information about how to add an EXT-to-DID mapping, see the <Contact List> parameter in

Chapter 6, “SPA9000 Field Reference”

Managing Voicemail

Subscribing to Voicemail Notification

The SPA9000 sends a one-time SUBSCRIBE for the message-summary event package for each line with a valid <Mailbox Subscribe URL>. The SUBSCRIBE implies subscription for the status of all the mailboxes associated with the voicemail account used-ID; it does not include any mailbox ID in the request. Following is an example:

SUBSCRIBE sip:mailbox-subscribe-url SIP/2.0 Via: SIP/2.0/UDP 172.16.22.23:5062;branch=z9hG4bK-44f9d0f0 From: Line 3 <sip:14089991003@sip.myitsp.com>;tag=ac6013983cce7526 To: <sip:mailbox-subscribe-url> Call-ID: ace86200-bbe839de@172.16.22.23 CSeq: 63017 SUBSCRIBE Max-Forwards: 70 Contact: <sip:14089991003@172.16.22.23:5062> Expires: 2147483647 Event: message-summary User-Agent: Sipura/SPA9000-3.2.2 Content-Length: 0

Note that the Expires value is purposely set to a very large number so the subscription does not expire and there is no need to renew the subscription. The voicemail server is expected to send a NOTIFY immediately upon receiving this SUBSCRIBE message for each mailbox on this account. The Request-URI of the NOTIFY should reference the CONTACT header of the corresponding SUBSCRIBE, but the user-ID in the To header should be the mailbox ID. The following example shows a NOTIFY for the mailbox ID 5031 on the account 14089991003:

NOTIFY sip:14089991003@172.16.22.23:5062 SIP/2.0 Via: SIP/2.0/UDP 178.178.221.230;branch=z9hG4bK-44f9d0f0 From: <sip:voicemail@sip.myitsp.com>;tag=ab789 To: <sip:5031@172.16.22.23:5062>;tag=ac6013983cce7526 Call-ID: ace86200-bbe839de@178.178.221.230 CSeq: 537 NOTIFY Expires: 2147483647 Event: message-summary User-Agent: ITSP/Voicemail-Server Content-Length: 0

Using Dial Plans

This section describes the dial plan features of the SPA9000. It also explains how to configure and write scripts and provides a reference describing the use of each dial plan parameter. For information about dial plans for the Auto-Attendant, refer to

Configuring Dial Plans

The SPA9000 allows each line to be configured with a distinct dial plan. The dial plan specifies how to interpret digit sequences dialed by the user, and how to convert those sequences into an outbound dial string.

The SPA9000 syntax for the dial plan closely resembles the corresponding syntax specified by MGCP and MEGACO. Some extensions are added that are useful in an end-point.

Dial Plan Digit Sequences

The plans contain a series of digit sequences, separated by the | character. The collection of sequences is enclosed in parentheses.

Using Dial Plans

Chapter 5, “Configuring the LVS Auto-Attendant.”

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.

Any one of a set of terminating events triggers the SPA9000 to either accept the user-dialed sequence and transmit it to initiate a call, or else to reject it as invalid. The terminating events are as follows:

• No candidate sequences remain—The number is rejected.

• Only one candidate sequence remains, and it has been matched completely—The number is

accepted and transmitted after any transformations indicated by the dial plan, unless the sequence is barred by the dial plan, in which case the number is rejected.

• A timeout occurs—The digit sequence is accepted and transmitted as dialed if incomplete, or

transformed as per the dial plan if complete.

• An explicit “send” (user presses the # key)—The digit sequence is accepted and transmitted as

dialed if incomplete, or transformed as according to the dial plan if complete.

The time-out duration depends on the matching state. If no candidate sequences are as yet complete (as dialed), the Interdigit_Long_Timeout applies. If a candidate sequence is complete, but there exists one or more incomplete candidates, then the <Interdigit_Short_Timeout> applies.

The following table describes the entries to use when programming the dial plan.

Dial Plan Entry Function

*xx Allows arbitrary 2-digit star code

[3469]11 Allows x11 sequences (for example, 311, 411, 611, 911)

0 Dials operator

00 Dials international operator

[2-9]xxxxxx Dials US local number

Dial Plan Rules

This section describes the rules that apply to configuring and interpreting dial plans.

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

Digit Sequence Syntax

Each digit sequence within the dial plan consists of a series of elements, which are individually matched to the keys pressed by the user. Elements can be one of the following:

• Individual keys 0, 1, 2 . . . 9, *, #.

Chapter 4 Configuring SPA9000 Features

Dial Plan Entry Function

1xxx[2-9]xxxxxx Dials US 1 + 10-digit long distance number

xxxxxxxxxx. Dials all other numbers, including international long distance

• The letter x matches any one numeric digit (0 .. 9)

• A subset of keys within brackets (allows ranges): for example, [389] means 3 or 8 or 9)

Element Repetition

Any element can be repeated zero or more times by appending a period (.) to the element. Thus, “01.” matches “0”, “01”, “011”, “0111”, … and so on.

Sub-sequence Substitution

A sub-sequence of keys (possibly empty) can be automatically replaced with a different sub-sequence using an angle bracket notation: < dialed-subsequence : transmitted-subsequence >. So, for example, “<8:1650>xxxxxxx” would match “85551212” and transmit “16505551212”.

Inter-sequence Tones

An “outside line” dial tone can be generated within a sequence by appending a comma (,) between digits. Thus, the sequence “9, 1xxxxxxxxxx” sounds an “outside line” dial tone after the user presses 9, until the 1 is pressed.

–

Numeric ranges (n-n) are allowed within the brackets: for example, [2-9] means any digit from 2 through 9)

–

Ranges can be combined with other keys: e.g. [235-8*] means 2 or 3 or 5 or 6 or 7 or 8 or *.

Number Barring

Linksys SPA9000 Administrator Guide

4-10

A sequence can be barred (rejected) by placing a ! character at the end of the sequence. Thus, “1900xxxxxxx!” automatically rejects all 900 area code numbers from being dialed.
