pjsip is a multimedia communication library based on the SIP protocol.
It is integrated with a rich media and a NAT traversal library
supporting the ICE protocol. It is very portable and has a small
footprint for embedded use.

A Python binding for creating SIP multimedia client using high level SIP and media API was added, as well as experimental SIP TLS transport support, Visual Studio 2005 support, WAV playlists, explicit SIP transport binding, and a faster G.711 codec implementation. Many bugs were fixed.
