Call Handler (Auto Attendant)
-----------------------------

.. _19.1.1|VOSS-515:

A call handler transfers telephone calls to the extension of a user or department
without the intervention of a receptionist or operator, via a
system of voice menus that the person initiating the call interacts with, using their
telephone keypad or voice commands.


.. note::

   Auto Attendant is a comprehensive service that provides for the provisioning,
   configuration and management of call handlers, greetings, schedules, and related
   dialplan components in Cisco Unity Connection (CUC) and Cisco Unified Communications
   Manager (CUCM).


Some call handler systems are comprised of message-only information menus and voice
menus, which allow organizations to provide business information such
as hours, directions to their premises, information about job opportunities, and
to answer other frequently-asked questions. Once the message plays, the caller
can be forwarded to a receptionist or they can return to the main menu.

Call handlers can be created at either customer level or at site Level:

* When created at customer level, a Network Device List (NDL) must be selected to instruct 
  the workflow which UC Application Servers to provision. 
* When created at site level, the NDL associated to the site is chosen automatically.
