Google+ offers free voice calls to U.S. and Canada from Hangouts
Google staffer Jarkko Oikarinen made the announcement, from where else, Google+.
That means anyone can join a Google+ video chat even if they are not online. Just call them and they can join the Hangout session.
The new feature is available inside Hangouts with extras (plus.google.com/hangouts/extras). To add someone by phone: click invite at the top of the hangouts with extras window. Then click the phone tab on the left of the window and punch in the number. Click call now.
