Why can't I make phone calls using Whatsapp with my Nokia Lumia 635?

[Windows Central Question]

Can't make phone calls using whatsapp with Nokia Lumia 635

So got my dad this phone, and we downloaded whatsapp but apparently this app is not supported by this phone because if he made a call using the app, the app would just reroute the call and use our provider's network. This caused us to have over 1k in overcharges because he was calling internationally thinking he was calling through whatsapp. I searched everywhere but haven't found a way to fix this. Anyone else had this problem??

The WhatsApp calling feature is not yet available for Windows Phones. It's currently being tested in the WhatsApp Beta version, we do not know when it will be released to the general public.
