CS 1000 Release 4.0 supports Session Initiation Protocol (SIP). SIP is a
protocol standard used for establishing, modifying, and terminating
conference and telephony sessions in IP networks. A SIP session can be a
simple two-way telephone call or it can be a collaborative multimedia
conference session. SIP initiates real-time, multimedia sessions which can
integrate voice, data, and video. CS 1000 Release 4.0 supports SIP phones.
Nortel Networks supports certified compatible third party SIP phones. In
contrast to IP Phones, SIP Phones use an industry standard open
standards-based signaling protocol, whereas IP Phone signaling is UNIStim
based. A Signaling Server is required to establish signaling for SIP Phones
and SIP Phones exchange signaling with SIP components residing on the
Signaling Server. Available features for SIP Phones depend on the devices
themselves, and the communication server, and vary from manufacturer to
manufacturer and between models. Features are delivered to IP Phones from
the communication server.
