Problem is likely a codec mismatch.  Do you have MTP checked on the trunk between CUCM and CUCME?  When you make calls from the phone to CME, are you sure it is negotiating G729? 

47 typically means a transcoder couldn't be invoked when it wanted one.  I would start looking at codec to see if you can find out what the issue is.

Hi Ahmed, I found same problem with you before, Did you try to unchecked "Wait for Far End H.245 Terminal Capability Set" on H323 Gateway on CUCM configuration?
