We’ll file this one in the "still has to prove itself" folder. Earthcaller is a web based (Activex powered) application that promises 100% free calls within the United States.

The couple of times I tried it ended in complete silence and not a ringing phone in sight.

The service is still in an early beta, so I can forgive them for not having enough capacity. Time will tell whether they have what it takes to deliver a working service, or whether I’m stuck using Skype and Magicjack for my free calls. The best part of this application (if it works) is that you don’t have to install anything on your laptop, which is great for corporate machines. Though the installation of an Activex applet might still be blocked by your IT department…

Try it out for yourself. Did it work for you? Leave a comment!
