VoIP technology however is developing and some of the developments that will ensure the future of VoIP are outlined in this paper. Session Initiation Protocol (SIP) retrieves server responses and handles client requests. This technology is able to determine the end system that will be used for a communication session, automatically sets the relevant parameters of the communication at receiver and user ends and then manages call transfer and call termination.
