Exacty what post # 2 said, those number are exacty what you posted Toll Free Numbers they are not called Air Toll Free Numbers.
Also Just for your info I called the 1-800-GOOG 411 number once knowing I would be billed AirTime but to my surprise I got billed $2 for it, they reveresed the charges thinking it was just an error. However there billing system knows its a loophole and they closed it, so when you call it they will bill you $2, which is the fee to call 411.
