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
• SPA900 Series IP phones (SPA921, 922, 941, 942, and 962)

Chapter 1 Using the Linksys Voice System
The Linksys Voice System
Figure 1-1 The Linksys Voice System (LVS) with the SPA9000 and SPA400
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 aninternal 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.”

This following summarizes the features provided by the SPA9000:
• SIP Application Server, Proxy, Registrar and Location Server (RFC3261)
• Multiple Service Provider Lines / SIP Account Support (4)

Technology Background
Technology Background
This section provides background information about the technology and protocols used by the SPA9000
system. It includes the following topics:
• Session Initiation Protocol, page 1-6
• SPA9000 Media Proxy, page 1-7
• Using the SPA9000 with a Firewall or Router, page 1-8
• SPA400 SIP-PSTN Gateway, page 1-8
• Network Address Translation (NAT), page 1-9
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).
Figure 1-2 SIP Requests and Responses
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).
