Release Notes: This version brings SIP/TCP and SIP/TLS as network protocols. It adds the G722 audio codec and the VP8 video codec. Users can also create audio conferences and choose SRTP as the media encryption method.
Release Notes: This version improves Mac OS X integration with desktop menus, better sound system handling, and binary bundle generation for ease of installation. It also improves memory usage and fixes a few SIP bugs.
Release Notes: This major version brings a totally new GTK+ graphical interface, designed to be more user-friendly and running with the same aspect on both Linux and Windows XP. It also runs in the background as an icon into the system tray. Firewall workarounds are implemented: double SIP registration and STUN. The available bandwidth is more efficiently used by the video stream, and a new H.264 codec plugin is available for download to experience with high quality video. Many old bugfixes are included in this release too.
Release Notes: This version uses the latest release of the eXosip library, which leads to many new SIP features: reINVITE, INVITE without SDP, and handling of video-fast-update requests in SIP INFO messages and early media. It also integrates the experimental and promising SNOW video codec of the ffmpeg project.
Release Notes: This version adds support for the MPEG4 video codec and makes the Theora video codec streaming usage compliant with Xiph's proposed standard. The GNOME interface has been added, with a new tab to control video codecs order and activation. Finally, the bandwidth management has been revisited to become more accurate by taking into account upload and download bandwidth limitations for both sides, which is required to have a working video communication with all kinds of network connectivity.
Release Notes: This release includes a new framework for audio-video processing and streaming called mediastreamer2 that has speed up the development of new features: echo-cancelation, stable video support with H263-1998, experimental video support with the free theora codec (very efficient at low bandwidth), and the ability to use WAV files instead of a sound card (linphonec only).
Release Notes: The console version (linphonec) has been improved: readline support (for a bash-like behaviour) and new commands have been added. The video support through H263-1998/RFC2429 is mostly clean and operational.
Release Notes: New features include a new architecture for dynamically loadable plugins in order to support more codecs, cosmetic improvements in the Gnome interface, bugfixes, and Swedish and Brazilian translations. The experimental video support through H263-1998 has made progresses.
Release Notes: This releases adds chat functionality, ilbc codec support, and sip-uri auto-completion when using a default proxy, and provides IPv6 support bugfixes.
Release Notes: This major release brings many improvements, such as presence support (which notifies you when your friends are online), support for multiple SIP proxies with on-demand authentication, call logging, audio latency improved thanks to a RTP adaptive jitter, and a simplified build process on ARM-Linux.
