Overview
The Linksys Voice System (LVS) is an affordable, feature-rich, multi-line voice over IP (VoIP) telephone
system that provides sophisticated communication services to small business users. The LVS uses
standard TCP/IP protocols and can provide global connectivity through any Internet Telephony Service
Provider (ITSP) that supports Session Initiation Protocol (SIP). In addition, with the optional SPA400,
the LVS provides full interconnectivity with the Public Switched Telephone Network (PSTN).
The LVS solution, illustrated in Figure 1-1, provides a line of IP communication products that include
the following:
•
SPA9000 IP PBX
•
SPA400 SIP-PSTN gateway

Phones
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
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. Figure 1-2 illustrates a SIP request for connection to
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).

SIP UA
Note
In this manual, the term client station is used to describe any SIP UA (including IP phones) that registers
with the SPA9000.
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).

Chapter 1
Using the Linksys Voice System
Technology Background
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 with
media proxy enabled
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: parameter to True. 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.

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 (see Figure 1-4).

Network Address Translation (NAT)

translation (NA) device. It includes the following topics:

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.
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.

Technology Background
NAT Types
The different types of NAT implementation are 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, which 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 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 to 3 but you do not need to change the value of the parameter.
4.
To capture SIP signaling messages, under the Line tab, set to Full. The output
is named syslog.514.log.
Step 2
To determine the type of NAT your router is using set to yes.
Step 3
View the syslog messages to determine whether your network uses symmetric NAT.

Using the Linksys Voice System
SPA9000 Architecture
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.
•
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)
FXS1 and FXS2 correspond to the two physical FXS ports. The FXS ports can only register with the
local SIP proxy. The Call Park is used to maintain calls that are parked, and AA is a scriptable
auto-attendant application.

Interactive Voice Response
The Interactive Voice Response (IVR), which is strictly for administration purposes, lets you use an
analog phone to perform basic configuration and troubleshooting operations. To access the IVR, connect
an analog phone to an FXS port and press **** to access the IVR menu.
For detailed information about using the IVR, refer to the “Using the Interactive Voice Response
Interface” section on page 2-8. A convenient quick-reference for the IVR is available at the following
website:
http://www.linksys.com/
Setup Wizard
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 “Using the Wizard for Initial Configuration” section on page 2-13
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.
To access the administration web server, direct a browser to the Internet (WAN) interface of the
SPA9000. To determine this address, use IVR Option 110#.

Administration Web Server” section on page 2-22. 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: 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.
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:
•
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
Implementing LVS
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 “Using the Wizard for
Initial Configuration” section on page 2-13.
Using the SPA9000 as a Media Proxy
The SPA9000 can act 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.
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: 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).

ITSP
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.
SPA9000 Hardware
The following are the ports provided by the SPA9000:
•
Two analog (FXS) telephone ports (Phone 1 and Phone 2), which are designed for use by the
following devices:
– Analog telephone

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.
Linksys recommends using the SPA9000 with QoS-capable networking equipment that can prioritize the
VoIP application traffic. QoS features are available on many Linksys data networking switches and
routers. A QoS-enabled router prioritizes the packets going upstream to the ISP. Table 2-1 illustrates the
bandwidth budget using different codecs.

Initial Setup and Configuration
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
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 whether 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.
If you are using static IP addressing for the SPA400, you need to know the correct static IP address to
assign. To determine the dynamically assigned address of the SPA400, you can use the Setup Wizard or
view the DHCP client table for the broadband router.
To determine the current IP address of the SPA9000, complete the following steps.
Step 1
Connect an analog telephone to one of the FXS (RJ-11) ports on the SPA9000.
Step 2
Press **** on the keypad to access the IVR menu.

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.
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.

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
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.
Note
The SPA resyncs only when it is idle.
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
Reboot URL
The Reboot URL lets you reboot the SPA9000.

Provisioning
This section describes the provisioning functionality of the SPA9000. This section includes the
following topics:
•
Provisioning Capabilities, page 2-26
•
Configuration Profile, page 2-26
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.
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 (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.
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. 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 … . The encapsulated elements specify values for
individual parameters. Here is an example of a valid XML profile:
some secret
Yes
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
Linksys SPA9000 Administrator Guide

Advanced Methods of Configuration
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 Figure 2-20.
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 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.

To add a new IP phone to the SPA9000, connect the IP phone to the QoS switch to which the SPA9000
is connected and power on the unit.
To add a previously-used IP phone to the SPA9000, perform the following steps:
1.
Upgrade the IP phone with SPA9000-compatible firmware.
2.
Factory reset the unit.
3.
Power cycle the unit.
4.
Connect the unit to the switch.
The SPA9000 provisions only the necessary parameters to the client stations. It assumes the rest of the
parameters have appropriate values, which are either the default values or manually configured values.
For example, the SPA9000 provisions only Extension 1 on the client stations. Access the administration
web server using the Administrator account to manually configure other extensions on specific client
stations.
Manual Client Configuration
The client stations can also be manually configured with the contents of the profile served by the
SPA9000.
