What is SIP

May 15th, 2012 | Posted by admin in News - (0 Comments)

The Session Initiation Protocol (SIP) is a signaling protocol developed by the IETF as an alternative to H.323.

SIP is an ASCII-based protocol used for setting up and tearing down multimedia sessions over an IP network.

It is easy to implement and is, therefore, widely used for signaling over gateways. Because it is Transport layer independent, SIP can be used with UDP, TCP, and SCTP.

It is extensively implemented as the signaling protocol for voice in service provider VoIP networks and is supported by most IP telephony system vendors.
