The Smart Licensing Workflow:

1. After downloading and installing CUCM, you access the OS Admin page (Port 8443).
2. Navigate to System > Licensing.
3. Register the CUCM publisher with Cisco’s Smart Software Manager (SSM) using a registration token generated on Cisco.com.
4. The system will automatically check for authorized licenses based on your contract.

Troubleshooting license errors: If you see "Evaluation period expired" or "License Reservation failed," your contract does not cover CUCM 12.5 specifically. You must purchase an upgrade or trade-in license.
