Forced Authorization Code (FAC) Management using Device Models
---------------------------------------------------------------

This method is typically used if you want to manage FAC codes within the context
of a given cluster (or only have single cluster deployments). You can add/mod/del
FAC codes in the system including via the bulk capabilities of VOSS-4-UC. If there
won't be large number of FAC codes implemented and/or this remains an advanced
administration task, this might be the best approach.

To manage FAC codes using this method, select the FAC Codes menu (exposed via the
``device/cucm/FacInfo`` device model):


To add a FAC code
.................

1. Browse to the appropriate hierarchy level for the FAC code (e.g. Customer or
   Site).
#. Navigate to the FAC Code menu item which will give a list of existing codes.
#. Click **Add**. If there is more than one Unified CM cluster at that hierarchy,
   then you will get a pop-up to choose the appropriate cluster.
#. Enter the details of the FAC code to be added in the form and click **Save**.


To modify an existing code
..........................

1. Navigate to the FAC Code menu item which will give a list of existing codes.
   Use the filters and/or hierarchy breadcrumb to locate the code to modify and
   then select it. 
#. Edit the settings and click **Save**.


To delete an existing code
..........................

1. Navigate to the FAC Code menu item which will give a list of existing codes.
#. Use the filters and/or hierarchy breadcrumb to locate the code(s) to delete. 
#. You can either select the code(s) from the list view via the check boxes and
   click **Delete** OR open the appropriate code and click **Delete**.
