Recorded message using bad English (e.g., "...once it get expired...") says that the IRS has four charges against you and therefore you need to call them back at 202-222-0207. This is a scam; the IRS does not call people -- you can check their policy by going to their website www.irs.gov.
Four working hours and once it get expired after that you will be taking under custody by the local cops as there are four serious allegations pressed on your name at this moment. We would request you to get back to us so that we can discuss about this case before taking any legal action against you. The number to reach us is 202-222-0207. I repeat 202-222-0207. Thank you."
