Just curious here, in your CallManager H.323 gateway definition, does the IP address show up in a state of "unregistered"? If so, try issuing a reset from that CallManager page.

After some more digging, it seems to be a VRF issue. Below is the
output of debug ip packet and debug h225 events. I see some packets
sent out the wrong interface. G0/1960 is in the global routing table.
