After the user logs in the UCM6510 web UI, the user will be automatically logged out after certain timeout.
This timeout value can be specified under UCM6510 web GUI->Settings->Login Timeout Settings page.
The "User Login Timeout" value is in minute and the default setting is 10 minutes. If the user doesn't make
