If you enabled Incoming call notification in Settings, the Smart CID is working
whenever there is an incoming call to the deskphone. When you press the Close
button (X), it is not displayed on the screen but it still remains in the notification bar.
Therefore, you can load it anytime. You can accept or reject a call.
When you accept a call, it is connected through the Samsung Mobile VoIP app.
