VOCAL: Open Source VoIP Software for Linux
An Anonymous Coward writes: "While most Open Source projects are applications and utilities intended for single users, David Bryan and David Kelly did something different.
They created an infrastructure project -- a VoIP phone system that either can run on a single box attached to a couple of IP phones or can scale up to a network of hosts processing hundreds of
calls between thousands of users. In this informative technical article at ELJonline, Bryan and Kelly detail the 'Vovida Open Communications Applications Library' ('VOCAL') project, a fully functional phone system that can run on either Red Hat Linux or Sun Solaris."
Why wasn't a link to the project's actual webpage in the submission? Here it is.
The Unix crowd might be interested to note that Yahoo has renewed interest in the Unix clients. An updated version was on freshmeat.net today, this is a 0.99.17 release that supports Linux (RPMs _and_ DEBs), Solaris and FreeBSD. While it doesn't have VoIP just yet (nearly all other features), it does seem fairly certain to do VoIP and Webcam.
Seems like the closest to a true cross platform VoIP app
