Google brings free voice calls to Hangouts, really wants you to hang out

Google's Hangout feature has just become a little more Hangout-y, now that the folks in Mountain View have integrated free voice calls within Google+. Available to users within the US and Canada, this new "extra" feature allows social networkers to place calls directly from a Hangout, allowing the recipient to remotely join in on the conversation at hand. To set it up, all you have to do is start a Hangout, hit the "Invite" button, and dial up your friend's number. Users can also use the feature to place individual calls without setting up a Google Voice account, though they'll need one if they wanna talk to someone overseas.
