React-Native - Enable to create call when using CallKeep in React-Native use npm install react-native-callkeep - (App crash when I init call)

[viv578ek]

I have setup CallKeep in react native

Import RNCallKeep
**import RNCallKeep from "react-native-callkeep";**

**Init setup CallKeep**
RNCallKeep.setup(options).then(accepted => {});

**When I make a Outgoing Call using start call** 
RNCallKeep.startCall(uuid, number, number, generic, false); 

**I am also add Libraries** 
 -> project -> Target -> Frameworks, Libraries and Embedded Content and Add CallKit.frameworks

**AppDelegate.m added some function**
#import "RNCallKeep.h"

- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void(^)(NSArray * __nullable restorableObjects))restorationHandler
{
 return [RNCallKeep application:application continueUserActivity:userActivity restorationHandler:restorationHandler];
}      

 **When I start a call App crashed main.m iOS file** 
 #import <UIKit/UIKit.h>
 #import "AppDelegate.h"

 int main(int argc, char * argv[]) {
@autoreleasepool {
   return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
  }
 }

**App Crash Line main.m
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));**

It's because you need to activate the audio session in your sip/webrtc library. If you use any variation of react-native-sip-pjsip - then you do it like this:

const endpoint = new Endpoint();
await endpoint.start()

    RNCallKeep.addEventListener('didActivateAudioSession', () => {
      endpoint.activateAudioSession()
    })

    RNCallKeep.addEventListener('didReceiveStartCallAction', () => {
      endpoint.deactivateAudioSession()
    })

Otherwise the client don't know when/if an audio session should start/stop. On iOS, CallKit ensures the call is given priority. But if you never say when the session should start, it will crash your app.
