I answered the call. It was automated message: "IRS we are filing suite against you. please contact us immediately at ...the same number". I think it's a prank....
Its not a prank, its extortion and they are serious about it! I posted the links to this above, This extortion scam has been around a few years also. Most of these calls are coming out of India and Pakistan.
Just checked my messages on my house phone and it was California saying the IRS is opening a law suit against me. I knew it was a scam because usually the IRS contacts you by mail first I believe. But checked anyways. Stupid scammers!
