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 an application layer control protocol that supports five parts of making and stopping communications. It does not provide services, therefore it acts with other protocols to provide these services, one of which is typically RTP that carries the voice for a call.IP is a standardized protocol with its basis coming from the IP community and in most cases uses UDP or TCP. The protocol can be used for setting up, modifying and terminating two-party (unicast), or multiparty (multicast) sessions consisting of one or more media streams.
