just call the number back & you'll get the prerecorded message identifying them...

Some Auto Warranty Sales Call.

This number called twice.  I didn't answer because I didn't recognize the number and I knew it was out of state because of the area code.  Anyway,   this is the message:

The person's name was Alyssa Brown and she said she was calling from the investigation department for the internal revenue service and an arrest warrant has been issued in my name.  Failure to get back to us in the next few hours your case file will be forwarded to your local police department and you will be arrested on the charges.

I had heard about these scams recently, so I blocked the number, submitted a complaint to the proper authorities and now I'm alerting the public.
