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

.. _19.1.1|VOSS-515:
     
Auto Attendant is an overarching service that caters for the provisioning,
configuration and management of Call Handlers, Greetings, Schedules and related
dialplan components in Cisco Unity Connection and Cisco Unified Communications
Manager.

A Call Handler transfers telephone calls to the extension of a user or department
without the intervention of a receptionist or operator. This is achieved via a
system of voice menus that the person initiating the call interacts with via their
telephone keypad or via voice commands.

In some Call Handler systems, there are message-only information menus and voice
menus that are used so that an organization can provide business information such
as hours, directions to their premises, information about job opportunities, and
answer other frequently-asked questions. After the message has played, the caller
can be forwarded to the receptionist or they can return to the main menu.

Call Handlers can be created at either Customer or Site Level. If created at
Customer level, a Network Device List (NDL) must be selected to instruct the
workflow which UC Application Servers to provision. If created at Site level, the
NDL associated to the site is chosen automatically.
