Open Source Telephony

Projects

• The Open Wengo project, a p2p-based system (like Skype), but open source (using the GPL License), is here at http://www.openwengo.com/index.php/whatisit

• An open source alternative to Skype is Project Gizmo, at http://www.theregister.co.uk/2005/07/05/project_gizmo_voip/

“Whereas Skype has selectively licensed usage of an API that offers limited insight into a closed protocol, a closed ecosystem solely controlled by one organization, the SIP protocol is open. Free open-source proxy/server implementations are sprouting up, and many developers are actively working on SIP clients. The Gizmo Project is the first to bring a truly-usable, user-friendly, cross-platform SIP client."
