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.
Nortel 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.
