We have been getting calls from this number for the past 5 days and just now decided to look it up on google.... wow i had no idea!! I had heard about this kind of thing.
You will be billed for it...as it is a collect call from a Florida Prison.
I had the misfortune of having my answering machine pickup up those calls, and even though my machine did not OK the call...how could it...I was still billed by some outside phone company as a piggy back charge onto my AT&T phone bill.
Since then, I have turned off my answering machine.
