@raosanat can you transfer this to your repo for action?

[raosanat]

I am assuming your application is doing the CallKit integration ? We are working on new API's to be added to support this.

[dudeck]

Yes, we integrated our app with CallKit. That's great that you're working on this feature, we'll use it as soon as it's ready and stable for our purposes.

Although we have a similar issue after a phone call (with a different error code - 561017449), this case is about alarm notification.

I hope you're able to reproduce this issue.

@dudeck are you still able to reproduce the issue using the latest iOS SDK? I will close the issue for now since it's over a year old. Please re-open the issue if you can still repro with iOS SDK 2.6.1
