GNU SIP Witch is a 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.
|
|
|
|
GNU SIP Witch is designed to support network scaling of telephony services,
|
|
rather than the heavily compute-bound solutions we find in use today. This means
|
|
a call node has a local authentication/registration database, and this will be
|
|
mirrored, so that any active call node in a cluster will be able to accept and
|
|
service a call. This allows for the possibility of live failover support in the
|
|
future as well.
