Didn't answer, but a voice message was left. It was a recording telling me that a law suit is being filed against me by the IRS, and to call the number back to receive more information. I did not call back, as I don't believe this is legitimate. I received this call last night, and two more this morning (one of which woke me up at 6:30 a.m.) from a different number (347-669-5232) that left the same message.
