How to remove callback option UI of CallKit after ending the call - ios

Question

In my app i'm using CallKit for incoming call. There is no outgoing call feature in the app. Everything is fine but when the receiver or dailer ends the call it shows the CallKit UI with call back option. I don't want to show callback option, how can I do it?
My code for ending the call
func end(call: SpeakerboxCall) {
let endCallAction = CXEndCallAction(call: call.uuid)
let transaction = CXTransaction()
transaction.addAction(endCallAction)
requestTransaction(transaction, action: "endCall")
}
private func requestTransaction(_ transaction: CXTransaction, action:
String = "") {
callController.request(transaction) { error in
if let error = error {
print("Error requesting transaction: \(error)")
} else {
print("Requested transaction \(action) successfully")
}
}
}

Answer 1

I have solved it. I was force quitting the CallKit where the transaction is not correctly completing.
AppDelegate.shared.providerDelegate?.provider.reportCall(with: call.uuid, endedAt: nil, reason: CXCallEndedReason.remoteEnded)
We need to set endedAt to nil and reason to remoteEnded

Close All Call (Swift4)
func performEndCallAction() {
for call in self.cxCallController.callObserver.calls {
let endCallAction = CXEndCallAction(call: call.uuid)
let transaction = CXTransaction(action: endCallAction)
cxCallController.request(transaction) { error in
if let error = error {
NSLog("EndCallAction transaction request failed: \(error.localizedDescription).")
return
}
NSLog("EndCallAction transaction request successful")
}
}
}
