SNOW-818 Keep-alive for improved VoIP NAT traversal

NAT keep-alive is a feature that sends very tiny UDP data packets from a VoIP client to the router to show that the port is still in use. Turbine and INCA are now sending keep-alives every 25 seconds if have enabled "NAT Keep Alive" under Call Settings.

Known Issues

MTN-2360 Client side forwarding does not work in SIP mode

Client side forwarding, which can be configured as a DAK action or activated from INCA display menu, does not work in SIP mode. Workaround is to use SIP server side forwarding.

IP Desktop Video Station can't receive video from TCIV if HTTP basic authentication is enabled on TCIV station. This does not affect TCIV stations running on or earlier. Workaround is to disable HTTP basic authentication for HTTP MJPEG.

MTN-1052 PTT does not work between Gateway and INCA station

Make a call between Inca and Gateway. Pressing * and # on mobile phone configured on Gateway does not effect conversation direction on INCA. If call is made between Turbine and Gateway, PTT works as expected.
