Thank you very much for your assistance. I will try your steps.
If the voicemail issue has stopped, I think I'm going to disconnect the alarm dialer first, as the redialing noise appears to be the only continuing issue, and perhaps that is also what is disconnecting my calls, as the dialer is meant to seize an open line. Does my logic make sense?
Based on my last post, because no one touched any inside phone wiring, and I don't have fios phone service, do you no longer believe it is related to Verizon's reconnection of the outside fios line(s)?
