Android receives a background call with broadcast receiver and pass it to RN headless JS

// Application index.js
AppRegistry.registerHeadlessTask('BackgroundCallTaskService', () => ({
    call_state,
    call_sid,
    call_from, // this is the phone number or contact string from twilio
    call_to,
}) => {
    console.log('####### CALL RECEIVED')
    if (callState === 'PENDING') {
        // this needs to call the Android Phone app, because it is not possible to start the RN activity
    }
    return Promise.resolve();
});

Application AndroidManifest.xml

<service android:name="com.hoxfon.react.RNTwilioVoice.BackgroundCallTaskService"/>

<receiver android:name="com.hoxfon.react.RNTwilioVoice.BackgroundCallReceiver" android:exported="true">
    <intent-filter>
        <action android:name="com.hoxfon.HoxFon.DEV.debug.BACKGROUND_CALL" />
    </intent-filter>
</receiver>
