Chapter 4: Overview
Introduction
This chapter describes the hardware and software features of the
Avaya 1100 Series IP
Deskphones and provides a brief overview of Session Initiation Protocol (SIP). In this
document, Avaya 1100 Series IP Deskphones will be referred to as IP Deskphones.
Avaya 1100 Series IP Deskphones with SIP Software
The
Avaya 1100 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 come with UNIStim software installed and must be converted to SIP
software.
If you have an IP Deskphone with UNIStim software, you can convert the software to SIP
software. To download the most recent version of SIP software, see
Download the SIP
Software to the provisioning server on page 28.
This guide explains how to:
• configure the provisioning server and the DHCP server. Note: The provisioning server
contains the software and the configuration files for the IP Deskphones reside. This is not
the IP Client Manager (IPCM) of the Call Server.
• convert an IP Deskphone with UNIStim software to an IP Deskphone with SIP software
• provision the Device Settings parameters on the IP Deskphone with SIP software
Important:
Converting the software on an IP
Deskphone from UNIStim software to SIP software
overwrites the UNIStim software. The IP Deskphone cannot operate in both modes
simultaneously. A switch from UNIStim to SIP software or SIP to UNIStim software requires
a software reload.
The following figure shows the main components of the Avaya 1165E IP Deskphone with SIP
software.
