real-time voice (calling) using WiFi P2P manager on android

Question

I have searched for way to make real-time voice (calls) between two peers but only found how to record voices and send them or sending photos and text. but what I want is for the two peers to be able to call each other. So is it possible that using WiFi P2P manager on android would allow me to create a real-time conversation between the two peers? Does android have that feature?
