This release contains minor bugfixes for the stable branch, such as build errors when TCP is disabled, a bug in strict route processing, and error parsing the compact form of SIP headers.
Several bugs have been fixed, including a crash
when resolving a bad hostname, not enough pool
memory when parsing DNS response, a crash with
some USB sound devices on Linux, an SDP media
direction negotiation bug, and some more.
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.
This release adds several new features such as support for the iLBC codec, a Windows Mobile target, presence event publication/PUBLISH, call transfer with norefersub, tone generator (fixed or floating point), experimental AEC, and more.
