Recording said this was a final notice that they had been trying to reach us that a lawsuit by the IRS had been filed and to return the call to that number.

Did you actually pick up the phone and hear a recording? I just got a recording with just the phone number only and when I try and call back with a private number no one answers. So this is a suspicious call to me!

I just got the same phone call. I believe that it is a scam. If you call back that may be all they need to bill your phone with some charges.

Just received a call from this number. And it was a recording. Saying final notice from IRS..

I don't pick up number I don't recognize, especially from out of town.  The voice mail message was just a recording repeating the phone number.
