I have called to UK and Germany and it works fine. First I tried it using SKYPE . Using SKYPE you can call anywhere in usa and canada. USE skype and call to that iowa based toll number if you do not have long distance on your home/office line or not much minutes or time for night calling. I did little research about this company and yes they do exist and there is no catch at all. there is no hidden charge or anything. They just wanna get the attention of millions of customer before they start the real business. If they keep gicing the free service, i guess they will bancrupt in few months. Use the service as long as they remain free.
