Then the CME configuration is irrelevant here as the issue is on CUCM side, are you using hardware or software bridge?

If software then what is the region between the CME trunk and the phone (what codec is defined) as you may need transcoders if G729 is defined due to the fact that software conference bridge only supports G711.
