Overview

Introduction

This chapter describes the hardware and firmware features of the Nortel IP
Phone 1120E and provides a brief overview of Session Initiation Protocol
(SIP).

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 Phones, telephony integrates easily with other Internet services.
SIP allows the convergence of voice and multimedia.

IP Phone 1120E with SIP Firmware

The IP Phone 1120E connects to an IP network using an Ethernet
connection. All voice and signaling information is converted into IP packets
and sent across the network.
The IP Phone 1120E can be ordered with UNIStim Firmware installed or
with SIP Firmware installed. UNIStim Firmware and SIP Firmware use the
same hardware, but the model number of an IP Phone 1120E with UNIStim
Firmware is different from the model number of an IP Phone 1120E with
SIP Firmware.
If you have an IP Phone 1120E with UNIStim Firmware, you can convert the
firmware to SIP Firmware. The most recent version of SIP Firmware can be
obtained from Nortel and installed on the IP Phone 1120E.
