SIP (Session Initiation Protocol) - Definition
The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol for creating, modifying, and terminating sessions with one or more participants. These sessions include Internet telephone calls, multimedia distribution, and multimedia conferences. SIP was accepted as a permanent element of the IMS architecture. It is widely used as a signaling protocol for Voice over IP, along with H.323 and others.
SIP is transport-independent, because SIP can be used with UDP, TCP, ATM, etc. It is text-based, allowing individuals to read SIP messages.
