The caller ID says "Wireless Caller".  They left a recording saying the IRS is filing a lawsuit against me, and I should call them back.  This is definitely a scam.  If you're not familiar with it, please see this page on the IRS's website  https://www.irs.gov/uac/newsroom/phone-scams- ... 6-filing-season

I've reported this incident to the TIGTA and FTC as the IRS requested.
