It seems that Facebook is working on something big according to the latest leaked screenshot that shows us a ‘Call’ button within Facebook’s messaging system.

We didn’t hear any rumours about voice calls within Facebook, so this latest leaked screenshot is quite a shock to many. As you can see from the screenshot, the new Call button is placed in the top right corner, right next to the chat and send message buttons. So does this button work? Well according to the screenshot, it seems that the person who made this screenshot is trying to find out that as well. Sadly, this button has been removed from the menu, we’re thinking that this is somehow related to Skype, because Skype and Facebook have been working together for a while, but that’s just our guess.
