This number called my home phone today at 2:45PM. I didn't answer the phone. They left a recorded message saying they are from the IRS and it was the official final notice. And the reason for the call was that they are filing a lawsuit on me. And to get more information on this case file I have to immediately call their department number 908-387-7920. I dialed the number back and got a busy signal. The caller ID said the call was from Phillipsburg New Jersey. Sounds like an IRS scam to me.
