Overview
Introduction
This chapter describes the hardware and firmware features of the Nortel IP
Phone E 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 E with SIP Firmware
The IP Phone E 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 E 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 E with UNIStim
Firmware is different from the model number of an IP Phone E with
SIP Firmware.
If you have an IP Phone E 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 1140E.
This guide explains how to:
•
configure the provisioning server and the DHCP server. Note The provisioning server is where the firmware and the configuration files for the IP Phone E reside. This is not the IP Client Manager (IPCM) of the call server.
•
convert an IP Phone E with UNIStim Firmware to an IP Phone
1140E with SIP Firmware
