While parked calls are parked on the telephone system and can be unparked by any other user, the parked call indication is sent to a particular extension. If there are any calls parked against your phone, you can view and unpark them via the Status menu.
Your system administrator can configure whether you can access this menu.
This menu is not supported on the J139.
To do this during a call, press the PHONE key and then press the Status soft key.
