T.38 Fax Relay MGCP VG224 2851 and CUCM7.1.3

Working samples below. Location had issues with incoming while utilizing Fax Pass-through. Converted to T.38 Fax Relay and customer could then make neither in nor outbound faxes. After converting to T.38 Fax Relay had to remove mgcp modem passthrough voip redundancy.

Works great now.
