How do Whatsapp voice calls work?

Are Whatsapp voice calls voice over IP? Do they use data rather than your network minutes? If so, does anyone know how much data a Whatsapp voice call would use, like say how many MB/minute?

There are NO Whatsapp voice calls. YET. Once they are on offer, they will use your data. How much of it per minute? Who knows...

Use Google Hangouts instead.
