I’m working on an iOS application that uses Azure Communication Services (ACS) for video calls. I’ve implemented clone github repository, and they work perfectly when the app is in the foreground or background. However, I encounter an issue when the app is killed (not running in the background). In this scenario, I don’t receive any incoming call notifications.

Here’s a summary of my setup:

1. iOS version: 17.5.1
2. ACS SDK : ‘AzureCommunicationCalling’, ‘2.11.0’
3. Github Repo Link : https://github.com/Azure-Samples/communication-services-ios-quickstarts/tree/main/add-video-calling-callkit

I’ve followed the ACS documentation and ensured that:

1. Push notifications are enabled in the app.
2. Background Modes in enabled (Remote Notification, Voice over IP, Audio and Background fetch).
3. Proper permissions are requested and granted by the user.
4. The device token is correctly registered with ACS.

Incoming call notifications are not being delivered when the app is killed. Is there something I’m missing, or is there a specific setup required to handle incoming call notifications when the app is not running?

Any help or guidance on resolving this issue would be greatly appreciated. Thank you!
