Many web sites on the internet are popping up where you can esentially make calls anywhere in the world for free. Traditional VOIP works by having your call routed over a shared data network to the other party. With the new VOIP business model, you go to a web site and enter your phone number and the other party's phone number (both of these phone numbers can be in different countries) and then click connect. At this point, both parties get an incoming call and neither party gets charged for making an outgoing call. Pretty cool stuff I think.
