Explanation

Two issues prevent synchronization here. First (B), Centralized Deployment in IM&P 12.0 requires OAuth Refresh Token login flow for secure inter-cluster communication. CUCM 10.5 does not support OAuth Refresh Token, making it incompatible with this feature at that version. Second (C), the synchronization link must be confirmed or initiated from the remote CUCM Administration menu - it is not a one-way push from IM&P alone. The administrator must log into the remote CUCM and complete the pairing action from that side. Without both conditions being met, the status will remain UnSynchronized regardless of other configuration.
