GNU oSIP

https://www.gnu.org/software/osip/
Library supporting the Session Initiation Protocol.

The GNU oSIP library is an implementation of SIP (as defined by RFC 3261).

This is the oSIP library (for Omnibus SIP), which consists of a parser and a transaction manager. It gives multimedia and telecom software developers an easy and powerful interface to initiate and control Session Initiation Protocol (SIP) based sessions in their applications. SIP is described in the RFC2543. The oSIP home page includes links to various useful SIP sites. 'oSIP' is little in size and code and thus could be use to implement IP soft-phone as well as embedded SIP software. oSIP is not limited to endpoint agents, and can also be used to implement "SIP proxy". It does not intend to provide a high layer API for controlling "SIP Session" at this step. Instead, it currently provides an API for the SIP message parser, SDP message parser, and library to handle "SIP transactions" as defined by the SIP document.
