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.

"The general opinion still seems to be that XMPP is good for right now for medium sized solutions. When people start looking at large portals and interdomain, they start looking at SIMPLE. You have seen folks like Nokia making more noise about OMA, PoC, and related things? Those tout SIMPLE pretty strongly."
