About This Guide

This guide describes how to install the 4600 Series IP Telephone product line and troubleshoot problems with the telephones.

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	H323 Protocol Supported?	SIP Protocol Supported?
4601	Yes	No
4601+	Yes	No
4602	Yes	Yes
4602SW	Yes	Yes
4602SW+	Yes	Yes
4606	Yes	No
4610SW	Yes	Yes
4612	Yes	No
4620	Yes	No
4620SW	Yes	Yes
4621SW	Yes	Yes
4622SW	Yes	No
4624	Yes	No
4625SW	Yes	No
4630	Yes	No
4630SW	Yes	No
4690	Yes	No

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 are supported only in Avaya server environments.

NOTE: Unless otherwise indicated, references in this document to the DEFINITY^� servers also refer to MultiVantage media servers.
