This number calls daily, no message left. Called back (blocking my number, of course) and it is a disconnected Verizon Wireless number.

Against my better judgment I picked up the phone, as I was expecting a call from this area code. Sure enough, there was no one at the other end, not even a recorded message. Most likely the call is part of a fishing expedition to find vulnerable phone numbers -- i.e., idiots like me who actually pick up.
