Many VoIP systems offer you free inbound calls but then charge you for outbound calls. Although these rates are usually pretty cheap, sometimes you just want things for free. In the guide, we’ll show you how to get a phone number and make inbound and outbound VoIP calls using your computer - for free.
We’re going to be using two services - Google’s Grand Central and Gizmo5. If you don’t already have a Grand Central account you might as well head over there now and reserve a number. Their website can tell you more about the service, which you’ll probably find is pretty awesome. Once Google blesses you with an account, they’ll give you your very own phone number attached to it.
Now head over to Gizmo5. You won’t need to wait to get an account there. Gizmo will also give you a free number (with a Nevada area code) and a client program for your computer - just like Skype. Gizmo5 gives you free inbound calls to your Nevada number, but to make outbound calls you have to buy credits. That’s where Grand Central comes in.
If you haven’t already, download the Gizmo5 client for your computer and open it up. The first time, it will ask you to log in - go ahead and do that.
Go back to Grand Central and log in. Under the settings tab, select Phones. From one of the drop downs, select Gizmo and enter the information for your Gizmo account.

At this point, you can also enter numbers to any other phone you may have and want to use with Grand Central. Take a look around to see what other potential things you could use Grand Central for.
Now hit the address book tab. Here you can import all the numbers from your computer’s address book, or just add a few numbers to try out. Go ahead an add the number you would like to dial out to. Once it appears in the list, click the “CALL” button next to it on the list.

Now simply select your gizmo account as the number to place the call from. Your gizmo account will start ringing.

As soon as you answer the call, Grand Central will then call the number you are dialing out to and connect you. Because Grand Central is initiating the call, it appears on your Gizmo account as a free inbound call. The number attached to your Grand Central account will be the one that shows up on caller ID, completely bypassing your Gizmo account number.
The system isn’t perfect - as you do have to initiate calls from the web interface - but it works. If you happen to have a Nokia N Series device, some enterprising hacker has put together a Grand Central Dialer application that will save you from the trouble of logging into the website each time. With some work, it could probably be made to run on any *nix system.
So there you have it - as much free calling as you want!
