Anonymous Reader 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 Voice-over-IP (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 Embedded Linux Journal Online, 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."
