User Sync Source
-------------------

.. _20.1.1|VOSS-551:

VOSS-4-UC provides a precedence hierarchy
of applications from which to sync user data.

For example:

If CCX data is synced, it will not overwrite user data
synced from CUCM or CUC. 

.. note::
   Data overwrite will take place according to the relevant
   mapping table that exists between VOSS-4-UC data
   application data.

Default precedence order:

=====================  ==========
Application            Precedence
=====================  ==========
MS_LDAP                 1
OPEN_LDAP               1
CUCM                    2
CUC                     3
AVAYA_SYSTEM_MANAGER    3
HCMF                   10
CCX                    10
BROADWORKS             10
MICROSOFT              10
WEBEX_TEAMS            10
ZOOM                   10
LOCAL                  99
=====================  ==========
