(This is fundamentally different from the “HoldConnection” function; with this function the connection to the caller is terminatedwhen the called subscriber puts down the handset). Parked calls are recorded in a liston the system terminal. The system offers the next available parking spot (0-9, * or #).Users can accept the calls from the list in whichever order they wish, enabling them to“unpark” specific calls as required. Until his call is “unparked”, the caller will hear musicon hold, provided music on hold has been configured. If the user does not “unpark”the caller after a certain amount of time, he will receive an automatic recall if thehandset has been replaced (the display shows information on the recall). This auto-matically “unparks” the caller. If, however, the user is still making another call and hasnot hung up, the caller will hear the busy tone and will be “unparked”.Authorisation for parking connections and the period of time after which there is arecall is defined by the administrator during the configuration of the system.Pick-up*: Accepts a call for another telephone in your pick-up group. Your first call isput on hold.(*: Not possible if there are already two active calls.)NoteIf a called subscriber is a member of a user group for which pick-up protection is ac-tive, then you cannot pick up calls to that subscriber’s number.
