Making phone calls from a computer should be as easy as typing a URL, and with the release of GizmoCall.com - a new service from SIPphone - it is. Typing http://gizmocall.com/18005551212 is all it takes. And it's not just easy, but free. You can get 10 minutes of free calling per day to call just about any phone number in the world (sorry Antarctica). Before Gizmo Call, you had to download a big program, install it, register for an account and buy calling minutes. With Gizmo Call, you just install a Flash plug-in into your web browser and begin talking.
