Overview
This chapter provides an overview of the Session Initiation Protocol (SIP)
application and how the phones fit into the network configuration.
SIP is the Internet Engineering Task Force (IETF) standard for multimedia
conferencing over IP. It is an ASCII-based, application-layer control protocol
(defined in RFC 3261) that can be used to establish, maintain, and terminate
calls between two or more endpoints. Like other voice over IP (VoIP)
protocols, SIP is designed to address the functions of signaling and session
management within a packet telephony network. Signaling allows call
information to be carried across network boundaries. Session management
provides the ability to control the attributes of an end-to-end call.
For the SoundPoint IP / SoundStation IP phones to successfully operate as a
SIP endpoint in your network, it must meet the following requirements:
•A working IP network is established.
•Routers are configured for VoIP.
•VoIP gateways are configured for SIP.
•The latest (or compatible) SoundPoint IP / SoundStation IP phone SIP
application image is available.
•A call server is active and configured to receive and send SIP messages.

This chapter contains information on:
•Where SoundPoint IP / SoundStation IP Phones Fit
•Session Initiation Protocol Application Architecture
•Available Features
•New Features in SIP 3.1
To install your SoundPoint IP / SoundStation IP phones on the network, refer
to Setting up Your System on page 3-1. To configure your SoundPoint IP /
SoundStation IP phones with the desired features, refer to Configuring Your

Administrator’s Guide SoundPoint IP / SoundStation IP

System on page 4-1. To troubleshoot any problems with your SoundPoint IP /
SoundStation IP phones on the network, refer to Troubleshooting Your
SoundPoint IP / SoundStation IP Phones on page 5-1.
Where SoundPoint IP / SoundStation IP Phones Fit
The phones connect physically to a standard office twisted-pair (IEEE 802.3)
10/100 megabytes per second Ethernet LAN and send and receive all data
using the same packet-based technology. Since the phone is a data terminal,
digitized audio being just another type of data from its perspective, the phone
is capable of vastly more than traditional business phones. AsSoundPoint IP /
SoundStation IP phones run the same protocols as your office personal
computer, many innovative applications can be developed without resorting
to specialized technology.
