GNU SIP Witch - secure peer-to-peer VoIP server that uses the SIP protocol
Calls can be made peer-to-peer behind NAT firewalls, and without needing a service provider. GNU SIP Witch does not perform codec operations and thereby enables SIP endpoints to directly peer negotiate call setting and process peer to peer media streaming even when when multiple SIP Witch call nodes at multiple locations are involved. This means GNU SIP Witch operates without introducing additional media latency or offering a central point for media intercept or capture. GNU SIP Witch can be used to build secure and intercept-free telephone systems that can operate over the public Internet.Wed 07 Nov 2012 01:05:18 PM CET - permalink -- http://www.gnu.org/software/sipwitch/
