- Welcome to the SIPWiki!
- "I have always wished that my computer would be as easy to use as my telephone. My wish has come true. I no longer know how to use my telephone." - Bjarne Stroustrup, the inventor of C++
The SIPWiki is dedicated to Session Initiation Protocol (SIP). See Mission Statement. Anyone may contribute. See the HowToWiki for instructions.
What is SIP?
SIP is a signaling protocol used for locating remote users and establishing interactive communications. It is analagous to setting up a call on the telephone network, with two critical improvements.
- It is internet-native, and therefore interoperates well with other protocols including, critically, future protocols (more at SIP RFCs and Specifications)
- It separates session establishment and session description, so specifying who (or what) you would like to connect to is independent of how you would like to communicate. (Compare calling someone's voice vs fax line, where the choice of how to communicate dictates how you connect.)
SIP is the glue for a new set of existing applications, beyond just the obvious 'IP telephone' to include multimedia, mobility, IM and presence, e-commerce, web services, and many others.
