SIP (Session Initiation Protocol)

SIP is a signaling protocol, widely used for controlling multimedia communication sessions such as voice and video calls over Internet Protocol (IP). The protocol can be used for creating, modifying and terminating two-party (unicast) or multiparty (multicast) sessions consisting of one or several media streams. Other feasible application examples include video conferencing, streaming multimedia distribution, instant messaging, presence information and online games.

The SIP protocol is a TCP/IP-based Application Layer protocol, designed to be independent of the underlying transport layer. It is a text-based protocol, incorporating many elements of the Hypertext Transfer Protocol (HTTP) and the Simple Mail Transfer Protocol (SMTP), allowing for direct inspection by administrators.

Many telecom vendors have adopted as the market for consumer SIP devices continues to expand. The free software community has also started to provide more and more of the SIP technology required to build both end points as well as proxy and registrar servers leading to a commodification of the technology, which accelerates global adoption.
