## About This Guide

This guide is for personnel who administer Avaya Communication Manager, DHCP, HTTP/HTTPS servers for 9600 Series IP Telephones, a Local Area Network (LAN), or a Web server.

The 9600 Series IP Telephones use Internet Protocol (IP) technology with Ethernet line interfaces and support the H.323 protocol only. The 9600 Series IP Telephones provide support for DHCP, HTTP, and HTTPS over IPv4/UDP, which enhance the administration and servicing of the telephones. These telephones use DHCP to obtain dynamic IP Addresses, and HTTPS or HTTP to download new versions of software or customized settings for the telephones.

NOTE: Unless otherwise indicated, any reference to “the DEFINITY® server” in this document also refers to Avaya Communication Manager media servers.

CAUTION: Avaya does not support many of the products mentioned in this document. Take care to ensure that there is adequate technical support available for servers used with any 9600 Series IP Telephone system. If the servers are not functioning correctly, the 9600 Series IP Telephones might not operate correctly.
