If the phone proceeds past the first stage of the startup process (LED buttons flashing on and off) but continues
to cycle through the messages that displays on the phone screen, the phone is not starting up properly. The

Unified Communications Manager server.
In addition, problems with security may prevent the phone from starting up properly. See
