SEMINAR ON SESSION INITIATION PROTOCOL : Session Initiation Protocol (SIP) is a protocol developed by IETF MMUSIC working Group and proposed to open, modify and terminate an interactive user session that involves multimedia elements such as video, voice, instant messaging, online games and virtual reality.
SIP clients traditionally use TCP and UDP port 5060 to connect to SIP servers and other SIP endpoints. SIP is used primarily for building and tearing down voice or video. However, it can be used in applications where the start of the session is a requirement. Among these events, subscription and notification, the mobility of terminals and so on. There are several SIP-related RFCs that define the behavior of these applications. All the audio / video communications are made on RTP.
motivational goal was to provide the SIP signaling protocol and call settings for IP-based communications solutions to support the superset of the call processing functions and features to the public telephone network (PSTN).
SIP-enabled telephony networks can also implement many of today require more advanced processing signaling system 7 (SS7), though the two protocols themselves are very different. SS7 is a highly centralized protocol, characterized by a complex network architecture and parameters of central fool (traditional telephony devices). SIP is a protocol for peer-to-peer.
