You can route incoming calls to the Auto Attendant port, and you can 
instruct the Auto Attendant to route these calls to any internal or external 
number.
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.

System Features
Affected by the Dial
Plan Configuration
The dial plan configuration affects several system features:
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.
