What is an auto attendant and what are its capabilities?

An auto attendant is an Interactive Voice Response (IVR) system which gives your callers the ability to hear audio prompts and to make selections using touch tone keys.

Menus and Events

An auto attendant comprised of one or more menus. A menu consists of a recorded message and corresponding keypress events. For example:

Main Greeting

“Thank you for calling Halloo Communications. Please select from the following options: Press 1 for sales, 2 for customer service...”

Events can be single key events like “1”, “2”, “3”, or sequences like “3375” and “5721”. Timeout events fire when a certain amount of time elapses with no key press.

Note that the Halloo IVR system is a multilevel auto attendant, meaning that you can create arbitrarily complex sub-menus and IVR trees for advanced applications requiring dozens or even hundreds of menus.
