Same IRS scam BS. Looks like they changed their number (or added one). I got the exact same recording yesterday from a different number. The interesting thing is that the recording actually tells you to call back on the number that the CID shows.
I just received a call from this number claiming that it was the final notice from IRS filing a law suit against me. I don't have any previous notices. I did not return the call after reading the comments here.
