Chapter 2: 9600 Series IP deskphone
overview
Overview of the 9600 Series IP Deskphones
Avaya 9608, 9608G, 9611G, 9621G, 9641G, and 9641GS IP deskphones use Internet Protocol
(IP) technology with Ethernet line interfaces and support both H.323 and SIP protocols. These
deskphones support DHCP, HTTP, and HTTPS to obtain customized settings and to download
new versions of software for the deskphones.
All 9600 Series IP Deskphones currently support the H.323 signaling protocol.
The H.323 standard provides real time audio, video, and data communications transmission over
a packet network. An H.323 telephone protocol stack comprises several protocols:
• H.225 for registration, admission, status (RAS), and call signaling
• H.245 for control signaling
• Real Time Transfer Protocol (RTP) and Secure Real Time Transfer Protocol (SRTP)
• Real Time Control Protocol (RTCP) and Secure Real Time Control Protocol (SRTCP)

Avaya does not support many of the products mentioned in this document. Ensure that
