GizmoCall is one of those VOIP software that doesn’t require any downloads and is therefore a space saver for your phone’s limited memory.
The service, called GizmoCall, launched this week. Unlike Skype, which requires users to download a software client to use the service, GizmoCall is Flash-based, requiring nothing more than a browser. Users simply go to the Web site, sign up for a username and password, and start making calls.
Just like other VoIP services, the allure of GizmoCall is that it provides free and low-cost calling. Free calls can be made to other GizmoCall users and to Gizmo5 users. Gizmo5 is a version of the same service that requires a software client and also provides other features, such as instant messaging.
