This is a scam claiming to be the IRS

Left threatening voicemail saying we had a missing judgement or court appearance and that this is our second official notice. They stressed DO NOT IGNORE THIS CALL. They never said their name or which company/agency they were calling from. Total scam.

Threatening voicemail and never identified themselves

Might have a federal offense or appear in front of the grand jury....doesn't say my name or what it is about. Supposed to call back or have my attorney call them. Warned not to ignore the call....good luck as it all unfolds around me. I'm so scared!! NOT!!!

Here is the message I received from this number.  It was an automated voice and the first part was cut off.  And then I had the same EXACT message from a different number a couple weeks later stating the same exact thing just a different phone number (the other number was 773-536-1321)

To tending your serious attention. Your case number is CF79621.  Ignoring this message will be an additional second attempt to avoid initial appearance before a magistrate, judge or the grand jury for a federal criminal offense. My number is (646) 582-0688. I repeat it (646) 582-0688. Do not disregard this message and do return the call. Now if you don’t return the call and I don’t hear from your attorney either the only thing I can do is wish you good luck as the situation unfolds on you. Goodbye.
