Summary:SIP is an application-layer control protocol that can establish, modify, and terminate multimedia sessions (conferences) such as Internet telephony calls. The Objective is to relinquish the SIP UDP transport process from the SIP gateway architecture (Voice application) running on IOS(Internetworking OS) and make it as an independent process running on Linux OS. The paper deals with the UDP (User Datagram Protocol) Socket Handler for SIP Service Provider under Linux Environment and the functionality of SIP UDP process which will handle the incoming messages from Network Layer (NL) and placing those messages on SIP Stack, followed by forwarding incoming messages will be sent to Application layer(AL) and Converse with the methods of Linux System Calls,Socket(),Setsockopt(),connect(),Bind(),Accept(),close(), Select() and Using POSIX Message Queue System calls.
