Google Voice has become a part of Gmail. You'll need to install the Google voice and video chat plug-in. Calls to the U.S. and Canada will be free. International calling rates are available here. Dialing a phone number works just like a normal phone. Just click “Call phone” at the top of your chat list and dial a number or enter a contact’s name.
