About 9600 Series IP Deskphones
The 9600 Series IP Deskphones support either the SIP signaling protocol or the H.323 signaling
protocol. This document covers SIP administration for 9608, 9611G, 9621G, and 9641G
Deskphones only.
SIP was developed by the IETF. Like H.323, SIP provides for real time audio, video, and data
communications transmission over a packet network. SIP uses various messages, or methods,
to provide:
●
Registration (REGISTER),
●
Call signaling (INVITE, BYE)
●
Control signaling (SUBSCRIBE, NOTIFY)
9600 Series SIP Deskphones support Media Encryption (SRTP) and use built-in Avaya SIP
Certificates for trust management. Trust management involves downloading certificates for
additional trusted Certificate Authorities (CA) and the policy management of those CAs. Identity
management is handled by Simple Certificate Enrollment Protocol (SCEP) with phone
certificates and private keys.
The 9600 Series IP Deskphones are loaded with either H.323 or SIP software as part of
initialization during installation. Post-installation, software upgrades automatically download
using the proper signaling protocol.
Different SIP software versions support different 9600 Series IP Deskphones, as shown:
