Google Hangouts. Google Hangouts is a communication platform developed by Google which includes instant messaging, video chat, SMS and VOIP features. It replaces three messaging products that Google had implemented concurrently within its services, including Google Talk, Google+ Messenger (formerly: Huddle), and Hangouts, a video chat system present within Google+.
If you've used the Google Voice app in the past, you may have set it to use your Voice number when making calls. These calls still used your carrier minutes, instead of your data signal. As a solution, Google created a second app that acts as a plug-in for Hangouts, called Hangouts Dialer. This app will add a dialer tab to Hangouts, allowing you to make outbound calls with your Voice number over Wi-Fi/data (VoIP).
