Top-Down User Management
------------------------

A top-down approach to user management means users and lines are configured on
VOSS-4-UC and pushed into Cisco Unified Communications Manager (Unified CM).
Users may be added via LDAP sync, the Admin Portal, or bulk loading. When users are
pushed to Unified CM the user's primary extension is created, and when a phone
is self-provisioned for the user, the phone is automatically moved to the user's
Site.

Use either of the following methods to configure the user in VOSS-4-UC:

* Generate the user's primary line and self-service ID using a line mask,
  universal line template, and a user profile at the site level.
* Set the self-service ID per user using Quick Add Subscriber.

.. note::

   You can associate multiple devices (Jabber, iPhone, iPad, 78xx series IP phones,
   and 88xx series IP phones) to a single subscriber through VOSS-4-UC
   (Subscriber Management > Subscribers). This cannot be done through Quick Add
   Subscriber (QAS) as the default 9971 is added through QAS.

   Using a combination of the methods above is possible but is not recommended.
   For example, you can enable the line mask at the site and use Quick Add
   Subscriber to set the primary line for some users while not setting it for
   others. When the line mask is applied, it first checks to see if a primary
   extension is already assigned to the user (perhaps via Quick Add Subscriber).
   If a primary extension is already assigned, the line mask is not applied.
