I'm not aware of any known caveats of that nature regarding that upgrade path.

Any recent network changes between ccm and the gateways since the upgrade?

I have seen situations with MGCP where the ccm side of the gateway config had 
to be rebuilt after a CCM upgrade.

Are you running an ED code version on the gateway? Check for caveats in your 
gateway code version with ccm 10.5.1

Have you restarted the MGCP process on the gateways (inside a maintenance 
window)?

In a more drastic approach, you could try and reintegrate the gateways as h.323 
and see if the issue persists.

Thanks,

Ryan
