LYSD uses VOIP telephone systems in all of it's schools. Basically, this means we supply each school with a handful of analog phone lines and split them digitally into enough lines for every room in the building. If you have any trouble at all with these units, please inform your tech department.
To begin with the most common problem, this post will address how to reset the unit to factory defaults.
At any point you can follow these keystrokes:
Mute > 2 > 5 > 3 > 2 > 7 > #
Clear all values > # (yes)
Are you sure > # (yes)
Phone begins reconfiguration.
If you cannot reach a normal configuration, you can always "press * to program."
# (next) > repeat until you see no new values.
The phone has been reset which will perform the same way as though a user has logged off of their own extension.
The phone will say enter extension and press the # key. At this point, simply log into the phone with the extension you wish to use. The last step is to press "login" on the LED display.
