I received a call from this number yesterday and just heard the message. Claims to be William Rogers with Dept of Legal Affairs of the US Treasury. I must call him back or be in grave legal peril. If anyone else gets the call it is a scam. I may or may not call to see what he will do. Not falling for this old trick.
I called a salon and was somehow linked to a radio station calling themselves KLFA saying I won a trip for two to the Bahamas. Immediately I got a text from this number listed above telling me to claim my prize. 30 minutes later I got another text. Looks like they moved on from IRS scams to free vacations.
