Received a call from this number on 8/24/16. I didn't answer so it reached my voicemail. I received an automated message saying the reason for the call was to alert me that the IRS is suing me and urging me to call back ASAP. I didn't bother to call back, clearly this is a scam because on no planet would this be the official way the IRS would notify someone of a pending lawsuit. Blocked.
