jSIP looks to implement the Session Initiation Protocol, a text-based protocol for initiating collaborative sessions between users. SIP has been designated by the IETF as an Internet protocol, with its specifications in RFC 2543. In addition to building the SIP protocol as specified, jSIP will look to provide prototype implementations of some of the SIP extensions, most notably for Instant Messaging.
