Call me maybe? Introducing free voice calls from Hangouts

Starting today you can make voice calls from Hangouts on Android, iOS and the web. It’s free to call other Hangouts users, it’s free to call numbers in the U.S. and Canada, and the international rates are really low. So keeping in touch is easier and more affordable than ever.

To get started on Android, just grab the new version of Hangouts (v2.3, rolling out over the next few days), then install the accompanying dialer to turn on voice calls. On iOS and the web, voice calls will be available the next time you open the app.
