Chapter 4: Overview

Introduction
This chapter describes the hardware and software features of the Avaya 1220 IP Deskphone and
Avaya 1230 IP Deskphone with SIP Software Release 4.4. In this document, Avaya 1200 Series IP
Deskphones are referred to as IP Deskphones.
SIP overview
Session Initiation Protocol (SIP) is a signaling protocol used for establishing multimedia sessions in
an Internet Protocol (IP) network.
SIP is a text-based protocol similar to HTTP and SMTP. With the introduction of SIP to IP
Deskphones, telephony integrates easily with other Internet services. SIP allows the convergence of
voice and multimedia.
Avaya 1200 Series IP Deskphones with SIP Software
The Avaya 1200 Series IP Deskphones connect to an IP network using an Ethernet connection. All
voice and signaling information is converted into IP packets and sent across the network.
IP Deskphones can be ordered with UNIStim software installed or with SIP software installed.
UNIStim software and SIP software use the same hardware, but the order number of an IP
Deskphone with UNIStim software is different from the order number of an IP Deskphone with SIP
software.
If you have an IP Deskphone with UNIStim software, you can convert the software to SIP software.
For information on how to convert the UNIStim software to SIP software and download the most
recent version of SIP software, see
This chapter explains how to:
• configure the provisioning server and the DHCP server. Note: The provisioning server is where
the software and the configuration files for the IP Deskphones.
• convert an IP Deskphone with UNIStim software to an IP Deskphone with SIP software
• provision the Device Settings parameters on the IP Deskphones with SIP software
