I have a UC560 system with a mix of 7945 and 7965 phones. We have employees that both work in the office and at their home.
I have configured the settings in CME to turn the backlight on during workdays (8:30 - 5:00) and off during after-hours:
service phone displayOnDuration 08:30
service phone displayOnWhenIncomingCall 1
service phone daysDisplayNotActive 1,7
service phone displayIdleTimeout 00:05
service phone displayOnTime 08:30
I wanted to know if there was a configuration setting that would keep the phone's backlight off, if the phone lost connectivity after-hours (while the backlight is normally off)?
We have a couple people who work from home and they mention if their connection ever drops in the middle of the night (usually due to the ISP performing maintenance), it causes the phone's display to turn on and display the "Configuring IP" and "Registering" messages.
This is of course important to see during the normal work day (when the backlight is typically on), but not as important after hours (when the backlight is typically off).
Some of our employeess have resorted to unplugging their router and phone at the end of the work day, which I don't usually prefer in case we have to do after-hours maintenance.
