SIP and the Art of Converged Communications

White Paper | June 18, 2013

Session Initiation Protocol (SIP) is an internet signaling protocol, developed by the IETF (starting in 1996), for establishing, maintaining, and tearing down sessions between a variety of real-time media, including voice, video, and chat.

It also relies on Session Description Protocol (SDP) to negotiate capabilities and codecs.
