IRS says that it is a scam:

It suggests filing a report with TIGTA and FTC so they can investigate these incidences. Don't give out any information at all! Hang up immediately! File a report with the FTC if you gave them any information, especially financial information.
did not recognize the number and did not pick up. robo message left, something about IRS lawsuit. Most likely a scam. A google search does not return IRS information on the number displayed on CID and message did not say specific name or person just generic message about a lawsuit. Also CID only displayed city/state info along with the number no IRS info on CID.
I just got the same call as the person above. I really don't think the IRS is A. Taking me to court, or B. Leaving a robo message about it on my phone.
