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

.. _19.3.1|VOSS-639:


The **Number Cooling Auto Expiry Schedule** (**IniCoolingExpiryCleanupService**) is a background 
process that runs daily to poll the **Cooling End Date** field on the Number Inventory list 
view, in order to determine which numbers have completed their cooling period. 

Numbers that have reached their cooling end date are returned to the pool of available 
numbers at the specific hierarchy. 

This process picks up any numbers with a cooling end date within the last 20 days. In this way, it can 
identify any numbers that reached their cooling end date while the system was down, or if the 
schedule was disabled for any reason. 

Numbers with a cooling end date older than 20 days must be removed from cooling manually. A system 
administrator can manually release any cooled number, regardless of its cooling end date. 



.. important::
   
   An ``hcsadmin`` user (or higher) can view and manage the **Number Cooling Auto Expiry 
   Schedule** (**IniCoolingExpiryCleanupService**) from the **Scheduling** list view. 
   
   While the ``hcsadmin`` user can edit this schedule, for example change the
   execution time or timezone, the schedule must run every day and should not be disabled.
