Explanation

The 'Unprovisioned' message on a Cisco IP phone means the phone successfully contacted CUCM, but CUCM has no device configuration for that phone's MAC address and auto-registration is disabled. Auto-registration allows unknown phones to register with a default configuration (directory number, device pool, etc.) automatically. When auto-registration is disabled and the phone has not been manually added to CUCM, CUCM rejects it as unprovisioned. The fix is either to enable auto-registration or manually add the phone's MAC address in CUCM before it attempts to register.
