After WhatsApp was bought by Facebook, the CEO Jan Koum tipped us that WhatsApp would soon bring voice call features (VoIP) to WhatsApp.

Since its 2014, a year full of leaks, iPhoneItalia posted leaked screenshots of the voice calling feature on iOS7. The images show a user interface that greatly resembles that of iOS 7 and has a few tweaks such as a camera button next to the voice message sending button, with a native like iOS 7 keyboard.



The VoIP feature shows a circular button UI and a blurry background. The voice calls will be free on Wifi and cellular networks in a move to compete favorably with other chats apps offering the service.
Only time will tell, how the final product will look like.
