We were excited when we got our hands on an unlaunched version of Google Voice for the desktop, which let users make and receive calls via a soft phone on their computer. We hear that software is still on ice, though, and won't be launched any time soon. But it probably doesn't matter - today Google Voice is being integrated right into the browser via Gmail. It's amazingly good - I know because I've been testing it for the last few days. Just download the Google Talk plugin for your browser and you can then make calls to any U.S. or Canadian phone number. And if you already use Google Voice you can make those calls anywhere else, too, for a very low per minute charge. The feature is fully integrated into Google Voice, which means you can set Google Voice to receive calls in Gmail, and use your Google Voice contact book. 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. Call quality is very, very good - comparable to Skype. See video below of test calls we performed. And more screenshots below:
