Just got a robo-call message from this number stating that they are the IRS and this is my official last notice that the IRS is filing a lawsuit against me!!! I have never received any IRS notices and just recently got my refund. As others have stated, this MUST be a scam but I am concerned.
I filed an online complaint with the FTC. the IRS does not make robo calls to threaten lawsuits. I suggest you all do the same - maybe volumes will help.

Thanks for the suggestion, I will add my complaint to yours. Hopefully enough will do the same... I agree with Penny that this scam is being directed towards older Americans. It's important we help protect anyone who receives these calls to the proper authorities... (see above)
