This is a scam number, not actually ACLJ, same with most every number now. Legitmate people will leave a message, all others have been hijacked including my own number... gee, I can't block my own number....sigh. I hope FCC fixes the DO NOT CALL list, sure isn't working now.
Comment on Charity Navigator: No problem Charity Navigator had delisted them because their operation was being run move like a scam than a charity. In August 2016, they BOUGHT the Charity Navigator and by Sept had given themselves a 4+ rating. You were still able to see the links to the articles pointing out why it was delisted, but it appears they're wiped.
