I have three landline phones and one phone number. One is a plug-in answering machine connected to jack #1 (closest to the incoming line from the phone company). All three rang until recently when the phone in jack #3 did not ring; the others ring fine. I thought the phone in jack #3 was bad but it works fine in jack #2 and the phone that was in jack #2 does not ring in jack #3. I even switched phone cords, and then switched DSL filters with the same result: jack #3 suddenly stopped supporting a ring. I can still use the phone in jack #3 to dial out or to pick up incoming calls if I hear the ring from the other phones, but I would like the phone connected to jack #3 to work. Any ideas how to solve this?
