SIP, in time
May 27, 2008
Work on the Session Initiation Protocol (SIP) began in 1996 and the first standards track specification (RFC 2543) was out in 1999. Many had high hopes that SIP, as a peer-to-peer protocol, would redefine the very nature of telecommunications. In the intervening years, there have been some deployments, some changes and a new standards track document, RFC 3261. But so far, SIP has only a relative toehold in the world of communications.
