Question

Is there any way decline a incoming call programmatically in swift. My code like this:

self.callCenter.callEventHandler = {(_ call: CTCall) -> Void in
            if call.callState == CTCallStateDisconnected {
                print("Call has been disconnected")
            }
            else if call.callState == CTCallStateConnected {
                print("Call has just been connected")
            }
            else if call.callState == CTCallStateIncoming {
                print("Call is incoming")
                }
            else {
                print("None of the conditions")
            }

I am detect incoming call state this way. But i don't know how can i change callstate of CTCAll . Please help me !.
