The call is dropping—unable to retrieve the incoming call state through the CoreDelegateStub's onCallStateChanged method.

When the app is in a killed state, it works fine on Network A. However, on Network B, the CoreDelegateStub's onCallStateChanged method randomly fails to receive the invite state for incoming calls during the day. Although we receive the PushKit notification every time, this issue prevents the call from connecting when the user attempts to accept it.

Hi,

Thank you for the logs. I’ll review them to identify the cause of the issue. In the meantime, could you test the behavior on other devices, such as Android, Windows, Mac, or Linux, and let me know if the issue persists?

This will help us determine if the problem is specific to Network B or related to the iOS device configuration.

Thank you for your patience, and feel free to reach out if you need any further information.

Best regards,
