My app uses react-native-webrtc and handles calls through it. It uses the device microphone by default. When a bluetooth headset is connected to the device, the app still routes the audio to be picked up from the device mic.

I tried to change this using the react-native-incall-manager lib. This worked for Android but iOS still uses the phone mic.

How do I re-route this so that it prioritizes whatever is connected. Is it something to do with react-native-webrtc or something else?
