Frequently Asked Questions
Agora SDK or WebRTC — which should I use?
Agora SDK is better for production apps needing reliability, global infrastructure, and low latency out of the box. Raw WebRTC gives more control but requires more infrastructure. I've shipped production with Agora and recommend it for most use cases.
Can push notifications trigger a real incoming call UI?
Yes — this is exactly what the Dil ki Baat platform does. Firebase FCM data-only high-priority notifications trigger a full incoming call screen on Android even when the app is in the background.
