Free PC to phone Calls by Bueno

Hi Friends,
Another way to make free calls to your friends in the USA through Bueno. The idea behind it is same as EarthCaller. You don't have to register to make a call that's the best part about it. But again for Firefox lovers it's a no-no as it only supports IE. Disable popups in IE to install a plugin by Bueno and enjoy its services. Post your comments about their service below.
