Auto Attendant: If there is at least one 1080 telephone in your system, it
may be set up to be an auto attendant. The auto attendant is assigned to pick
up a ringing line automatically after a selected number of rings. It may also
be set up to record messages for your extension. The auto attendant plays
the selected auto attendant message and redirects the call if the caller enters
an extension number.
Central message: If a 1080 telephone is assigned as an auto attendant, when
a call is answered by the auto attendant, and a caller presses [9], a central
