H.323 Gateway between CME 10.5 and CUCM 12

Hello,

I configured H.323 Gateway between CME 10.5 and CUCM 12, unfortunately I have the following challenges with calls:

CUCM to CUCM = Successful

CME to CME = Successful

CUCM to CME = Successful

But

CME to CUCM = Unsuccessful. for this, If I call from CME to CUCM, the phone registered under CUCM rings and when I answer the call, the voice is not passing through (If I answer call from CME to CUCM, there is no voice and calling phone i.e. phone from CME gives a busy tone after some 10 seconds. Note that If I answer call from CME to CUCM, the phone from CME still giving a tone that indicates the outgoing call then after 10 seconds it gives a busy tone).

Any documentation regarding this will highly be appreciated.

Your Kind support will highly appreciated
