Call Flow---PSTN---(SIP)------CUBE-----(SIP)-----CUCM8.5--------(SIP)------Rightfax Server
I have been battling this for a while and I'm stumped. IB and OB calls stay up for about 40-50-seconds and drop.
This is my IB Dial-Peer.
dial-peer voice 806 voip

The Wireshark traces on the destination RF server show that DCS isn't being sent from the Originating Fax. The provider is sending to the CUBE, but thats where it stops.
Any assistance would be greatly appreciated. I can provide configs/debugs/traces.
Thanks.
