I just spoke with the Verizon operator and she advised me this is the new way telemarketers are getting around the "Do Not Call" list. As long as their number is displayed on the caller ID, they are not subject to the "Do Not Call" regulations so they just use a number that is not a valid number when you call back so you can't get through to them. Should have known they'd figure out a way to go around the do not call regulations.
this call came in to a business line. they just hung up when we answered the phone. how darned rude. If you cant be civil on the phone dont be calling people, businesses or anyone else for that matter!
