Pushkit with Sinch VOIP not working with pushkit - ios

Question

I am trying to implement App-to-App calling with Sinch in my IOS app. I have implemented Pushkit in my iOS app with Sinch but the push notification is not working when the app is in background.
I have two questions.
Do I need another web service to send push notification to my app for incoming app separately or Sinch handles it itself.
If it does handle itself then what am I missing in my code.
#import "AppDelegate.h"
#interface AppDelegate ()
#end
#implementation AppDelegate

UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
[self handleLocalNotification:[launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey]];
self.push = [Sinch managedPushWithAPSEnvironment:SINAPSEnvironmentAutomatic];
self.push.delegate = self;
[self.push setDesiredPushTypeAutomatically];
[self.push registerUserNotificationSettings];
return YES;
}

If you integrated Pushkit and Sinch then push notification may can't catch on PushKit's delegate function - didReceiveIncomingPushWithPayload. But you can get push notification on SINManagedPushDelegate's function - didReceiveIncomingPushWithPayload.
Push notification is not coming but you can get incoming call event on there when app is in background. You can trigger local notification if app is in background to let user incoming call know.
Hope that would be helpful for you.
