About This Guide

This guide is for personnel who administer Avaya Aura™ Communication Manager, Avaya Aura
Communication Manager Branch (formerly known as Avaya Distributed Office), DHCP, HTTP/
HTTPS servers for Avaya 1600 Series IP Deskphones, a Local Area Network (LAN), or a Web
server.
The 1600 Series IP Telephones use Internet Protocol (IP) technology with Ethernet line
interfaces and support the H.323 protocol only. The 1600 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.
!CAUTION:
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 1600 Series IP Telephone system. If the servers are not functioning
correctly, the 1600 Series IP Telephones might not operate correctly.
