Same experience. Got a voicemail saying the IRS was suing me and to call this number. I pretty much knew it was a scam because the IRS almost always uses the US Mail as their source of contact. However, I called the number and got a man with an Indian accent. He was asking me for personal information that the IRS would clearly already have, so I hung up.
IRS Scammer. You website folks need to add a category on your "call type" pull down menu for scammer. I would laugh in the caller's face except I don't answer direct any more unless I recognize the caller ID.
