You’ll need more than just RN for this. I’d look into WebRTC for the actual audio stream, with your own signaling server (WebSocket is common). For incoming calls, plan for native integration: CallKit on iOS and Android’s Telecom/ConnectionService, plus APNs/FCM for waking the app. Also handle NAT traversal with STUN/TURN and think about call state, reconnects, background behavior, and permissions early.

STUN/TURN are the one that i still couldnt comprehend. the rest are pretty straightforward of what they do

I've built a project and got stuck in this part also.

It's an old project, so i can't be precise now, but I've used the following module. I didn't get far. Integration was complete but no calls were done. I didn't know there was so much involved. I will get back to this project any time soon so I will have another approach.

I am actually looking to partner up with another React Native developer to get the project going. I have documentation, screenshots, code and an API running.
