Internal number, freely selectable from the numbers in the internal supply of phone numbers. When put together with the ten possible park positions 0 - 9, this creates ten 3 to 4-digit phone numbers. These numbers can then be used to select the parking zone for call parking.

Freely selectable name. This name is used to identify the internal number within the PBX.

Specifies the maximum minutes a call is kept in the internal parking zone. After the hold time has elapsed, the user that put the call in the parking zone is again signalled that the call is still there. If this user is busy, the call is put back on hold in the parking zone. If the hold time elapses a second time without the call being transferred, the connection is disconnected and the caller hears the busy signal.
