These butt-wipes called my DNC listed phone at 1702 hrs today.  Realizing it was a spam/scam call, I simply picked up but did not speak.  The system disconnected almost immediately.  (Most robo-messaging systems apparently don't trigger until someone speaks.  Don't speak and most will disconnect by themselves.  It doesn't stop them from calling again and again because they're scam artists but at least you don't have to listen to the nonsense.)
