Skype !
Hey I use it quite a bit .. I call my neighbor 3 doors away on it. Computer to computer ! Works excellent..
I call my friend on Lordia Florida , I'm in south fla hes in central fla, He has a Iphone it works great on that also
I call Texas Fort Worth the connection there can be pretty bad at times . But it works . Its free ! Georgia is crystal clear from my location .. it is a little different every time I use it . But who cares its free...
Did I say its free? And its great fun to use even if the picture is a little fuzzy at times
Down load it and use it !
