About This Guide

This guide provides a description of Voice over IP and describes how to administer the DHCP,
TFTP, and HTTP servers. This guide also covers how to troubleshoot operational problems with
the 4600 Series IP Telephones and the servers.
The 4600 Series IP Telephone product line supports two signaling protocols, the Session
Initiation Protocol (SIP) and the H.323 protocol. The chart below shows the 4600 Series IP
Telephone models and the protocol(s) they support.
IP Telephone Model
4601
4602
4602SW
4610SW
4620
4620SW
4621SW
4622SW
4625SW
4630
4630SW
4690SW
Sets that support both protocols, for example, the 4610SW, do not support each protocol
simultaneously. Instead, a given telephone must be loaded with software that supports one
protocol or the other.
Telephones with H.323 software work only with Avaya Communication Manager call servers.
Telephones with SIP software can work in Avaya server environments as well as non-Avaya
server environments.
