Facebook has started the global roll-out of group calling in Messenger, which allows for voice calling with multiple friends at once.

“From any group conversations, just tap on the phone icon to initiate a group call. You can then manage individual participants on the next screen,” said Facebook’s David Marcus.

If you have the latest version of Messenger, you should see the phone icon appear in group conversations.

According to a report by TechCrunch, there is a limit of 50 participants per Facebook Messenger group call.
