Skype by Skype uses P2P (peer-to-peer) technology to connect you to other users to talk and chat. You can even access the regular phone line at a very decent price. Thank skype I was able to convince my fiancee to marry me and still have some money left (she is living in Croatia and calling her over the regular phone would cost a lot) to buy her nice rings.
