On Monday, Gizmo Project intro’d Gizmo Call, a super easy way to make calls from your browser. They say no traditional software download and installation is required, but you do have to install a Flash plugin (that’s kind of software isn’t it?) But, to get people using it, they’re offering five FREE minutes of calling anywhere. If you register with Gizmo, you get 10 minutes free. After your 10 minutes are up, you switch over to CallOut credits (roughly 2 cents/minute within North America). Pretty darn cheap.

Here’s some other tips I dug up about using GizmoCall.

- If you are calling another Gizmo user, which is technically a free call anyway, the “timer” will count down and the reset itself to the original value after the call so you won’t be using free minutes for free calls.

- Two-number Caller ID costs $4 per year. Once you’ve paid for this service, make sure you are still logged in and click the Caller ID tab. The page should reload after a few seconds to show the Mobile and Home fields. Enter the numbers (either one or both) you want to use for caller ID.

- To have a call history, you must register with GizmoCall. Registration is free and you receive 10 minutes free when logged in (only 5 minutes when not logged in).
