Who called from 6504881790

Robocall.  Long distance, prime time.  I answered the call but said nothing.  Their computer closed the line after 20 or so seconds.  If enough folks do this their telephone bill could be quite high, perhaps dissuading them from this business.

A second call from this same number, same treatment.  Calls 15 minutes apart.

More than likely it's a Scammer calling...IRS NEVER calls --they only send mail! Blocked them!

Incoming call but did not leave message.

BLOCK!
