Hello, colleagues.
I am reaching out to the community with an issue that is likely quite common. Unfortunately, I have not been able to resolve it independently and would like to confirm if my approach is correct.
Core Problem: VoIP push notifications are not delivered to the application when it is in the background or terminated. After reviewing existing discussions on the forum, I concluded that the cause might be related to CallKit not having enough time to register. However, in my case, I am using AppDelegate, and in theory, CallKit registration should occur quickly enough. Nevertheless, the issue persists.
Additional Question: I would also like to clarify the possibility of customizing the CallKit interface. Specifically, I am interested in adding custom buttons (for example, to open a door). Please advise if such functionality is supported by CallKit itself, or if a different approach is required for its implementation.
Thank you in advance for your time and attention to my questions. For a more detailed analysis, I have attached a fragment of my code below. I hope this will help clarify the situation.
