Reported on another site as a loud recording, probably a telemarketer or someone else you would have nothing to do with; a Salt Lake City phone number. Don't answer and block.

Money making scam.  Recording was a pain, called several times.

Get Rich quick scam

I did not answer this. "David" left a message about ways to earn $10,000 a month. and to give him a call back if I was interested. Just a money making scam.
