The updated calling interface isn’t available to everyone, but according to some Reddit users, if you already have the update you can get another person in on the voice calling action by placing a call to them, forcing the interface update. WhatsApp hasn’t made anything official just yet, so this is all pure speculation and trial and error.
Regardless, if you’ve been wanting voice calling through the app, you shouldn’t have to wait too much longer. If some users are seeing it, we can probably expect a massive launch for everyone in the near future.
