I just inherited a 3300 and have a huge laundry list of little things to work through
I have already found many of the solutions I need here on this Forum.
You guys really know your stuff.
I just got to one that I don’t know what to look for.
Symptom: When operator station (4025) is placed on night time, the phone rings and rings and rings.
(Even if no one is calling.) How can I stop the ringing?
