I work at home sometimes and just received a call from this number. I answered, "Internal Revenue Service, KB." There was no answer on the other end. Well see if they call back.
This message board has nothing to do with the caller. They don't own this board and don't read it. It's to post your experiences with the number that called you and so others will know WHO it is that the number belongs to and what they want. If you don't know who it is that called or can post what it is that they want, then you have nothing to offer this message board.
