is a free audio/video-conferencing application for Linux and other Unices (e.g BSD or MacOSX). It was written by Damien Sandras and is licensed under the GNU/GPL. It is based on the H.323 ITU standard and allows you to make audio and video calls to remote users with H.323 hardware or software (such as Microsoft Netmeeting). It also supports all modern videoconferencing features, such as registering to an Internet Locator Service (ILS) directory, gatekeeper support, making multi-user conference calls using an external Multipoint Control Unit (MCU), using modern Quicknet telephony cards and making PC-To-Phone calls.
