NightAttendant Ringing Constantly 1

[Bill3rd]

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?

I'll bet some of the rings are from someone zeroing out
at auto attendant or hangups or no touchtone entry

not really known, when ever someone picks up the set there is no one there.

turn off the onhook dialing in the voicemail class of service.
