[Android app] Hangouts Dialer enables voice calls on Hangouts

Over one year ago, in July of 2013, Google added voice calling to Hangouts on the web. In October 2013, Google added voice calling to the iOS Hangouts app. Today Google has released Hangouts Dialer for Android, which essentially enables voice calls within the Hangouts app. 

You can download the app directly on your Android device through the Google Play Store or by using the link which follows:

Requirements	Android 4.0.3 or greater; Google Hangouts

Google's Hangouts Dialer for Android lets you make voice calls to real phones all around the world. Calls to US or Canada are free, and rates to other countries tend to be fairly competitive with services like Skype. Even better, if you have a Google Voice number connected to your Hangouts, you can make and receive VoIP calls, meaning you can have data-only service and still get calls and texts.

In order to use Hangouts Dialer, you will have to download Hangouts for Android version 2.3 which is currently being rolled out. Once you have the Hangouts update, the dialer itself will appear as a tab in the Hangouts app, but you will need to have the Hangouts Dialer installed, because without it the tab won't be there.
