What is one advantage of importing Cisco Unity Connection users from Cisco Unified Communications Manager?

When a user is imported from CUCM and kept synchronized, the extension is controlled by CUCM and cannot be freely changed manually in Unity Connection because the sync would overwrite any manual change.

CUCM-synchronized users in Unity Connection maintain a live AXL-based synchronization link, so when an administrator changes a user's extension in CUCM the change is automatically reflected in Unity Connection, ensuring voicemail routing stays accurate without manual intervention.

Voicemail features such as greetings and call handling can be administered regardless of whether users are imported from CUCM or created locally in Unity Connection.

Unity Connection licensing is based on the number of users and mailboxes and is independent of how users are imported or provisioned.
