What Is SIP

The Session Initiation Protocol (SIP) is a signaling protocol The Session Initiation Protocol (SIP) is a signaling protocol used for establishing sessions in an IP network. A session used for establishing sessions in an IP network. A session could be a simple two-way telephone call or it could be a could be a simple two-way telephone call or it could be a collaborative multi-media conference session.collaborative multi-media conference session. SIP is SIP is developed purely as a mechanism to establish developed purely as a mechanism to establish sessions, it does not know about the details of a sessions, it does not know about the details of a session, it just initiates, terminates and modifies session, it just initiates, terminates and modifies sessions. sessions.
