How to receive call when app is not running?

Question

The bug scenario for User 2:

User 1 is calling User 2

iOS App is in termination state (killed)

Call UI is not shown

Call rejected by User 1

Now open app & call is receiving (CallKit UI shown) however call is terminated by User 1

The call is working in Foreground state Background state

Not working in Killed state

Capability: Background modes, Audio, airplay, VoIP, Background fetch, Remote notifications

I face this issue every time, also I'm unable to test calls in development mode. For testing, I have to make an AdHoc build & then I can test. In development, mode calls are not received in any scenario.

I want to receive call-in killed state also.
