CallKit prevent PushKit from being called

Question

I'm using PushKit and CallKit in my iOS app for sending and receiving calls. My problem is that when app is killed and I receive a call, didReceiveIncomingPushWith is called and I display a native call screen using the line

provider.reportNewIncomingCall(with: currentCallID, update: update, completion: { error in })

But once this line is called and native call screen appeared, in case of caller cancel the call, didReceiveIncomingPushWith is never called again.

What is strange is that if I commented this line

provider.reportNewIncomingCall(with: currentCallID, update: update, completion: { error in })

didReceiveIncomingPushWith is being called perfectly.

Does anyone have any explanation/solution?

Edit

I'm using XMPP server which has a socket open, in case I close this socket in didReceiveIncomingPushWith method it worked (but causes another issue that I couldn't answer as there connection is lost).

Answer 1

Whenever you cancel a call/terminal always invoke and tell the system that call has been changed his state with this method.

Objective-C

[provider reportCallWithUUID: currentCallID endedAtDate:endingDate reason:(CXCallEndedReasonDeclinedElsewhere)];

Swift

provider.reportCall(with: currentCallID, endedAt: endingDate, reason: .declinedElsewhere)
