Update

First, thanks to all who posted as I wanted a sense of how widespread my issue might be.

I've come to believe that I had one overly aggressive robocall machine that interpreted my answer machine as a viable contact. Within two hours of blocking all calls without identifiable numbers, the phone stopped ringing--all day and all night--except for identifiable callers. I haven't had this much quiet in years.

I'm beginning to think the robocall machines, used by various outfits, are somehow "connected" and share a large data base of numbers known to be active. Now that I've blocked all but spoofed numbers, my own number is out of play. I hope. At least that would explain the abrupt stopping of all incoming calls listed as "Incoming", "Out of Area," "Private Caller," "Unknown Number," etc.
