Session Initiation Protocol (SIP) is a signaling protocol used to create, manage and terminate sessions in an IP based network. SIP is a mechanism for call management. It also allows for the establishment of user location and provides for feature negotiation so that all of the participants in a session can agree on the features to be supported among them, and enables the ability to change features of a session while it is in progress.
