Actually, with the new triple-play offers from ADSL providers, calling the US from Europe can be free now. They simply have their own VoIP networks, and put a plug for any regular POTS phone on the router box. No computer needed (let alone dedicated software), and for the user there's no difference with a regular land line (except you can't use a modem or a fax on the line).
I have to say, I don't see the point of using a computer to phone these
days.
