While Facebook is obsessed with bots, it's not the only new feature the company has been working on for Messenger. The app will soon be getting group calls which, as its name implies, allows you to have an audio-based conversation with multiple people. With the latest version of the Messenger app, it's just a matter of tapping the phone icon while you're inside a group chat. Once you've done this, Facebook will give you a secondary screen to manage the people on the call. TechCrunch reports that you can have a maximum of 50 friends on a single group call.
