Computer said that this call was from IRS and this was the last attempt to reach me. I was instructed to call back on their line......at that point I hung up. What kind of scam is this now?

This is the IRS with an important announcement letting you know that a lawsuit is being filed against you by the IRS.  You must call this number to receive any further information.  This call was made to my home 5 times and it was very intimidating in its urgency.

We received the same phone calls as above "This is the IRS with an important announcement letting you know that a lawsuit is being filed against you by the IRS.  You must call this number to receive any further information." --- three times yesterday and twice today. Caller ID says East Provude RI.
