American Legal Services left voice mail claiming outstanding claims due / district attorney will be looking for me if I don't call them back. Quoted my name and ending SS#. I have been through this scam before and had my att Internet

   An attorney isn't going to do much good with these guys.  It's an offshore scam.  They're using Internet phones for communications.   The key to the scam is to scare you into thinking you're going to be arrested and getting you to give them your credit/debit card information.  

The best you can do is to tell them you are aware that it's a scam and not to bother calling you anymore.   It might also help to tell them that you've reported their number to various federal agencies.   Once they realize that they're not going to scare you into paying money that you don't owe, they'll move on to someone else.

  The real downside to this is that they actually do have your personal information.  According to reports here, they have enough info to commit identity theft.   While these particular scammers don't appear to be doing that, there's nothing to stop them from selling your info to crooks that might.    I'd recommend going to the FTC's identity theft web page and following the recommendations there.
