I would try two things:

mgcp bind media source-interface FastEthernet0/0

And these commands:

mgcp behavior g729-variants static-pt

mgcp behavior dynamically-change-codec-pt disable

These commands are for a workaround for a bug in the latest IOS. You didn't state your version so it was speculation. I wouldn't worry about these.
