Called this Saturday morning around 9:00 am Pacific time. IRS-is-filing-a-lawsuit scam call, but not the automated voice. Caller sounded like they were doing the call live but it was probably pre-recorded as they started the message before my outgoing message had finished playing (I have a machine, not VM).
This is a scam call, please do not call back or answer this number or fall for the dire warning. The IRS will never call you and they certainly won't wish you good luck if you don't call back. Caller ID said "New York NY".
