Open Source Telephony
This is a proposed project to successfully deploy an open source telephony solution on Mac OS X Server. Telephony is here described as a corporate call routing system with voice mail and other services. The goal would be to centralize all communications on one computer platform. Other potential benefits are integration and customization with other software solutions running on the OS X Server.
