What is SIP?
SIP or Session Initiation Protocol is a set of internet standards that enable voice, video and multimedia communications to operate over TCP/IP protocols. The core SIP standard was ratified in June of 2002 and thus has benefited from years of technical contribution from nearly every communications equipment supplier and service provider during its development as an internet standard. SIP enjoys wide acceptance and deployment both within service provider and enterprise networks.
