A nice addition to Hangouts with extras has been made available today over at plus.google.com/hangouts/extras, bringing with it the ability to place phone calls directly from within a hangout. Much like phone calls in Gmail, which recently got an international rollout, the feature will be available for free, initially to users in the US and Canada. Also, outgoing calls will come from your Google Voice number, if applicable. If you’re interested in trying it out, here’s how to do it:
1. Click Invite at the top of the hangouts with extras window
2. Click the Phone tab on the left of the window, and enter the phone number you wish to call.
3. Click Call now.
