CUP 8.6, CUCM 8.6 for OCS RCC

               hi we have the cup8.6, cucm 8.6 integrated to OCS for RCC.

All dashboard and system checks on cup are ticked ok. However on user MOC client we get the following error : 'cannot connect to the phone system, the call control server may be temporarily unavailble'    .

we have trunk from ccm to cup, in cup we have ACL's for OCS and in cup we have cti gateway and ctigw application user with 8 cti cucm's.

User was on a cup 7, with ccm 7 to same ocs and all worked fine, issues after migration to ccm 8 . Move user back to ccm 7, i.e. register the phone to old ccm and using cup 7 all works fine again.

Any advise appreciated.
