A Comprehensive Investigation of Sip Protocol

It has become ubiquitous that VoIP technology has revolutionized the communication media at various spectra. This paper’s pivotal focus is on investigation of the impact of session initiation protocol and its future course of supporting applications at various communication related requirements. As we are aware that VoIP, an extensively used technology, is very popular and is used to transmit both data and voice packets over a single line at the lowest cost.[1]Likewise, VoATM provides synchronous transmission and is the fastest of all. VoFR is another technology gaining colossal importance in the frame relay networks and its combination with VoIP and ATM is being designed for mass usage. Hence, there is always a need to invent and explore these technologies so that the technology is delivered to all the users at a reasonable cost and the best possible service is provided.Thus, each technology is better than the other technology in some way or another. Along side protocols like RTP and SIP protocols are used for multimedia and session oriented applications respectively. This paper tries to give a complete investigation of SIP protocol.
