Hi,
please provide a full call log of such a call and the full config (without any sensitive data like username, passwords, secrets, ...).

The default voip codec on a Cisco router/cube is G729. So my first guess would be that the voice-class codec may not be applied to the CUCM-facing dial-peer correctly.

If you would post the voice-class codec section and the dial-peer section from your CUBE here we can take a look and see what the configuration is telling us.

Possibly for some calls the dreaded dial peer 0 is used. That would make the codec be g729.

@devraj123 If you could capture the output for both a working and a non working call, in separate files, when you have debug voip ccapi inout and debug ccsip message turned on we could probably figure out what is going on. At least that would give us a good starting point.
