Got a call from this number just now. The next time they call, they will be treated to my anti-spam "blow a police whistle into the mic until they scream" dissuasion method. After being hung up on EVERY time I ask these scammers to NOT call back, I am done being polite. (BTW: Every spammer/scammer who has been on the receiving end of this method has NEVER called back. Guess it takes a blown eardrum to get these jerks to stop calling.)

How do we stop robo calls? Traveling in Europe and answering charges me $.

Same deal -- no message left but would have answered since I am in the same state. FYI

BLOCK the number and they can never get through.  I do not take calls from "unknown" numbers or from numbers I do not recognize, and look them up on BING, if not listed, they are blocked.  PLUS  use this  National Do Not Call Registry
