This is a bogus number claiming to be from the IRS and threatening legal action if you don't call back. They don't list the name they are calling for. If you call back the number they give you, it goes to voicemail and I've never heard back. We've gotten this same message from different numbers.

A voice recording said, " This is the last attempt that is being made. The IRS is suing you." They gave a phone number to call, but I didn't have anything to write it down.
