+## Receiving a call when the application is not reachable.
+
+In some case your application can be unreachable :
+- when the user kill the application 
+- when it's in background since a long time (eg: after ~5mn the os will kill all connections).
+
+To be able to wake up your application to display the incoming call, you can use [https://github.com/ianlin/react-native-voip-push-notification](react-native-voip-push-notification) on iOS or BackgroundMessaging from [react-native-firebase](https://rnfirebase.io/docs/v5.x.x/messaging/receiving-messages#4)-(Optional)(Android-only)-Listen-for-FCM-messages-in-the-background).
+
+You have to send a push to your application, like with Firebase for Android and with a library supporting PushKit pushes for iOS.
+
+### PushKit
+
+Since iOS 13, you'll have to report the incoming calls that wakes up your application, like in your `AppDelegate.m` :
+
+```objective-c
+- (void)pushRegistry:(PKPushRegistry *)registry didReceiveIncomingPushWithPayload:(PKPushPayload *)payload forType:(PKPushType)type withCompletionHandler:(void (^)(void))completion {
+  // Process the received push
+  [RNVoipPushNotificationManager didReceiveIncomingPushWithPayload:payload forType:(NSString *)type];
+
+  // Retrieve information like handle and callerName here
+
+  [RNCallKeep reportNewIncomingCall:uuid handle:handle handleType:@"generic" hasVideo:false localizedCallerName:callerName fromPushKit: YES];
+
+  completion();
+}
+```
+
 ## Debug
