Just got a call from this number. Immediately came to this site and saw the other post. Didn't answer since I didn't recognize the number, and no message was left.
I've seen people post this number and not have any luck in finding out who called. It's American Center for Law and Justice. I haven't answered the call and they haven't been obnoxious. I dailed the number and they did answer. But they do not leave a message on your phone.
