OpenH323
From RTEMSWiki
The OpenH323 project aims to create a full featured, interoperable, Open Source implementation of the ITU-T H.323 teleconferencing protocol that can be used by personal developers and commercial users without charge.
According to http://www.openh323.org/pipermail/openh323/2002-October/057716.html, the RTEMS port should be merged and in their standard distribution.
