[Spce-user] ngcpct='sip:127.0.0.1:5080' in Contact header

[Skyler]

I would run..

ngrep-sip b -d any -qt -W byline port 5060 >/tmp/ngcpct_check.txt

and make a test call. Then attach the txt to the list.

Thats not right is it?  at this point now, my calls to our gateway dont stay up for longer than 32Seconds then the audio drops out of the call and the person on the PSTN side of the call is disconnected completely, and my SPCE UA appears to have the call up still with no audio until I end the call.
