CAUTION: If you configure the Auto Attendant so that it can access any
external number, you risk the possibility of toll fraud. You can reduce the
possibility of toll fraud by explicitly putting specific external numbers into
the outgoing dial plan table. This precaution prevents outside callers from
dialing any external number except the ones that you define.
There are two types of routes:
Destination routes — Specify the extension of a destination device.
■
They can also perform digit manipulation operations on the dialed
digits that resulted in the selection of this route before those digits are
dialed on the destination device.
Timed routes — Specify time of day and day of week criteria which,
■
when met, result in a particular destination route being selected.
CAUTION: If you operate the NBX system in Keyset Mode, routes are not
applicable.
For more information, see "DestinationRoute Create" and "TimedRoute
Create" and related entries under "Dial Plan Configuration File
Commands" later in this chapter.
The dial plan configuration affects several system features:
Keyset Mode Operation Using the Dial Plan
■
Hybrid Mode Operation Using the Dial Plan
■
Off-Site Notification
■
Keyset Mode Operation Using the Dial Plan
If you map any telephone buttons that have LEDs to specific Analog Line
Card ports, you enable Keyset mode in the NBX system. Instead of dialing
a single digit (typically 8, 9, or 0) before placing an outside call, the user
presses a button to select an available Analog Line Card port. The user
defines the routing (that is, the selection of a destination device) by
pressing the button to select the Analog Line Card port; however the NBX
system controls the call using the dial plan.
You cannot map a digital line extension in Keyset mode.
The NBX system applies any Class of Service restrictions that are
associated with the user's telephone to determine whether to make a
call. The system also uses any pretranslator that a device uses and
performs any required digit manipulation operations before it actually
transmits the digits on the Analog Line Card or Digital Line Card port.
