Session Initiation Protocol Library (libsip)

This networking enhancement is new in the Solaris Express 12/06 release.

Session Initiation Protocol (SIP) is an application layer protocol that can be used to initiate, modify, and terminate multimedia sessions such as Voice-over-IP (VoIP) and Instant Messaging (IM).

SIP library in Solaris provides a SIP stack, that conforms to RFC 3261, and a set of API to write SIP applications. Primary users of this library include developers who write SIP applications such as soft phones, proxy servers, redirect servers, etc.

The library supports all SIP headers in RFCs 3261, 3262, 3265, 3323, and 3325.

For more information about SIP, see the sip(7P) man page.
