New Open Source VoIP software released - A new version of the VoIP ( voice over ip) Hopper security assessment tool was released earlier this week, with Nortel VLAN Discovery support.

Open Source Software VoIP for Linux
While most open-source projects are applications and utilities intended for single users, we did something different. We 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.


Our project is known as the Vovida Open Communications Applications Library (VOCAL), a fully functional phone system that can run on either Red Hat Linux or Sun Solaris. more
