SIP Overview (05 Jun 2006)

SIP - Session Initiation Protocol -> Good way to do Voice over IP.
SIP is a set of open standards managed by the IETF. Because of the open standards approach SIP devices are generally interoperable between different vendors. In a SIP based VoIP (voice over IP) system, most of the intelligence is in the phones rather than centrally in the PABX. This results in a much more scalable system. Installing additional phones only requires there to be a suitable network connection, apart from licensing issues, the system cannot become "full" unlike a PABX.

Is XMPP going to be the near term winner of the IM protocol battle? Comments from Robert Sparks - organizer of SIPit...
