Dialed back for the hell of it blocking my caller ID. Get the "We're sorry, the number you have dialed is not a working number..." Never ends with these a-holes. You figure out how to tell them apart from someone you want to talk to and they figure out how to make themselves appear as someone you want to talk to. Can't wait till someone comes up with a phone that will only let safe callers get through. Anyone know if there is such a service or phone with that feature?
