VG202 MGCP gateway fax issues

[jschnarkey]

Hello,
I have a VG202 gateway FXS. I can receive incoming faxes ok but outgoing to PSTN fail.
I see in wireshark traces that the RTP packets are being directed to my CUBE loopback address per the cucm in the SDP of the call and there is never an RTP response from this address.
I may not even be saying this correctly.
I see that incoming faxes use the CUBE address and the VG202 address
I see that outgoing calls use the CUBE loopback address and the VG202 address.
The call manager gateway list only has the CUBE address, not the loopback. I know the dial peers have the loopback bound but I am very new to this and want my faxes to work before I deploy any more of these gateways.

Thanks, Jake

My guess is you have a routing issue and the VG cant actually reach the loopback address.
