Session Initiation Protocol (SIP), connection management protocol developed by the IETF; H.323, one of the first VoIP call signaling and control protocols that found widespread implementation. Since the development of newer, less complex protocols such as MGCP and SIP, H.323 deployments are increasingly limited to carrying existing long-haul network traffic. [citation needed] Media Gateway Control Protocol (MGCP), connection management for media gateways
SIP is the Session Initiation Protocol. In IP and traditional telephony, network engineers have always made a clear distinction between two different phases of a voice call. The first phase is call setup, and includes all of the details needed to get two telephones talking.IP is used to transfer calls, terminate calls, and change call parameters in mid-session (such as adding a 3-way conference). One of the wonderful things about SIP is that it is a text-based protocol modeled on the request/response model used in HTTP.
