The Call Park feature (Call Park and Directed Call Park) allows you to manage call
park numbers from the Call Park list.

Call Parks can be added either individually or in bulk using number ranges.
   
Multiple call park numbers can be added in a single operation, which creates the
required number of individual call park numbers instead of creating masked ranges
of 10, etc.

Call Park and Directed Call Park can be configured as either service specific or
clusterwide, dependent on the status of the **Enable Clusterwide CallPark Number/Ranges**
parameter on the Unified CM.

Call Park allows you to select directory numbers from a drop-down list, but also
permits custom entries outside of the number inventory that can begin with '*' or '#',
which are then added to the Number Inventory.

.. note::

   Clusterwide call park numbers are available to devices hosted on any server
   within the Unified CM cluster. If clusterwide call park is disabled, the call
   park numbers are only available to devices on the nominated Unified CM server.



Clusterwide Call Park
......................

Call Park allows users to place a call on hold, so it can be retrieved from another
phone in the system, for example, a phone in another office or in a conference room.

If your users are on an active call at your phone, they can park the call to a call
park extension by pressing the **Park** softkey or the **Call Park** button. Someone
on another phone in your system can then dial the call park extension to retrieve
the call.

You can define either a single directory number or a range of directory numbers
for use as call park extension numbers. Users can park only one call at each call
park extension number.


Clusterwide Directed Call Park
................................

Directed Call Park allows a user to transfer a call to an available user-selected
directed call park number. 

Directed Call Park numbers are managed at site level, and allow a user to transfer
a call to an available user-selected directed call park number. Configured directed
call park numbers exist clusterwide. 
You can configure phones that support the directed call park Busy Lamp Field (BLF)
to monitor the busy/idle status of specific directed call park numbers. Users can
also use the BLF to speed dial a directed call park number.

Only one call can be parked at each directed call park number. To retrieve a parked
call, a user must dial a configured retrieval prefix followed by the directed call
park number at which the call is parked. Configure the retrieval prefix in the
Directed Call Park Configuration window.

.. note::

   Whenever changes are made to directed call park numbers, any devices that are
   configured to monitor those directed call park numbers by using the directed
   call BLF must restart to correct the display. Change notification automatically
   restarts impacted devices when it detects directed call park number changes.
   You also can use the Restart Devices button on the Directed Call Park
   Configuration window.
  
   
Adding Call Parks
.................

From the **Clusterwide Call Park** or **Clusterwide Directed Call Park** form
(default access via **Device Management > CUCM > Clusterwide Call Park or 
Clusterwide Directed Call Park**):

1. Click **Add**.
#. Browse to the required Site level.
#. Enter, at minimum, the following mandatory fields:

   * Range Size* - Enter a range size of 1 or more.
   * First Call or Directed Call Park Number*
   
     * Displays call park numbers which are **not used** and **available**. If
       **Range Size** > 1, only contiguous ranges are made available.
     * Numbers beginning with '*' or '#' are allowed as free form numbers. However,
       numbers with this prefix cannot be created in the directory number inventory
       so directory number inventory management is not available.
   * Description - this description is used in the directory number inventory list
     view and also the Unified CM call park number.
   * Partition (Directed Call Park only) - The route partition of the directed
     call park range, selected from the drop-down list.
   * CUCM Server* - (Call Park only) - This field is mandatory, and a CUCM Server
     must be selected **IF** the **Enable Clusterwide CallPark Number/Ranges**
     parameter on the Unified CM is set to **False**.
     
     .. If set to **True**, the **CUCM Server** field remains mandatory, but can be ignored.
     
   * Reversion Pattern (Directed Call Park only) - If a call is parked for longer
     than the allowed time, it reverts to the number selected from the drop-down
     list. Note that the allowed time is specified in the **Call Park Reversion
     Timer** parameter on the Unified CM.
     
     .. note::
     
        The **Enable Clusterwide CallPark Number/Ranges** and **Call Park Reversion
        Timer** parameters are located on the Unified CM under **System > Service
        Parameters - Service Parameter Configuration (Advanced) - Cisco CallManager
        (Active) Service > Clusterwide Parameters (Feature - General)** section.     
     
   * Revert CSS Name (Directed Call Park only) - This is the CSS that will be used
     to attempt to route the call to the reversion pattern above.
   * Retrieval Prefix* (Directed Call Park only) - for example, a '*' may be used
     to retrieve a number from the call park number.
#. Click **Save**.
