Number Cooling Auto Expiry Schedule
-----------------------------------

.. _19.3.1|VOSS-639:


An ``hcsadmin`` user (or higher) has access to the **Number Cooling Auto Expiry
Schedule** (**IniCoolingExpiryCleanupService**), which can be managed from the
**Scheduling** list view.

This schedule polls the **Cooling End Date** field on the **Number Inventory** list
view on a daily basis to determine which numbers have completed their cooling period.
These numbers are then returned to the pool of available numbers at the specific
hierarchy.

.. note::

   While the ``hcsadmin`` user can edit this schedule, for example change the
   execution time or timezone, the schedule **must run** every day, that is it
   **must not** be disabled.
