I answered and it was a robotic voice saying I needed to call back about a federal tax evasion case.

Tax evasion and tax fraud voice mail

It's just the IRS scam.  Ignore it. Block it.

Received a voicemail stating I or my attorney needed to call back otherwise I would be solely responsible for all debt.. but no clue as to who the collector was. When I called back I could not even understand a single word coming from the person on the other end of the call!!
