Poor quality tape recording. Man with an accent. Legal scam (go ahead...call him back and ask him to tell you your name, and since he has your address - because he knows your name and phone number- that you are standing by to be served by the local law enforcement folks). "Hi. This message is intended to contact you. My name is Steve Martin and I am calling regarding an enforcement action executed by US treasury intending your immediate attention. Ignoring this will be an intentional second attempt to avoid initial appearance before a magistrate judge or grand jury for a federal criminal offense. My number is 213-260-2296. I repeat 213-260-2296. I advise you to cooperate with us and help us to help you."
