After installing Cisco UAC Advanced the Cisco Unified Attendant Server is stuck at initializing, then reverts to service stopped. You will also just see the Engineering and Help Menu when logged in via Web Console.

Resolution

1. Run the TSP install, this should be located in the Desktop. (The installation process places this file here)
2. Restart the Server.
3. After restart the Cisco Unified Attendant Server service should be in a running state.
