The server in UHB has errors and is not functioning correctly. Kevin has opened a TAC case with Cisco and is restarting the server.
When the server is restarted phones will switch to the primary server in HSB and will fail back when the UHB server is restored.
The operator Station attendant console and Sangamon Auditorium ticket office attendant are the only known issue at this time.
We will keep the blog updated.
