Calls from PSTN to HQ did not went thru

HQ config #
mgcp
mgcp call-agent 10.1.200.21 service-type mgcp version 0.1
mgcp dtmf-relay voip codec all mode out-of-band
mgcp bind control source-interface GigabitEthernet0/0.1
mgcp bind media source-interface GigabitEthernet0/0.1

Something wrong with the above config, perhaps I should have bind mgcp with Loopback0
Anyway, removed following config out of HQ router made it worked.

Did all config with Loopback interface now
 mgcp bind control source-interface Loop0

 mgcp bind media source-interfaceLoop0
