If I call my home phone there’s no answer, it just rings. I don’t have AT&T Call Notes so there’s no answer.
I’m able to make and receive calls on my home phone number from the RJ31X jack in the panel. None of the landline wall jacks have dial tone now.
The ADT installer switched my service from landline to cellular notifications. He installed a new box next to the panel for this so I assume having the ADT equipment still plugged in to the RJ31X is a mistake unless that’s something for redundancy (try landline first then use cellular).
