Chapter 26 Dialing plan: Routing and destination codes
Note: The destination codes must not conflict with the following:
•
park prefix
•
external code
•
direct dial digit
•
Auto DN
•
DISA DN
•
Private access code
•
line pool codes

telephone DN
•

Alternate routes for routing schedules
When you select a route on the Destination Codes panel, the alternate schedules for that route
appear in a separate table. You only need to fill out this panel if your system is using routing
schedules.
Note that in these schedules you can configure three routes. The second route acts as fallback route
for the first route if it is unavailable. If the second route is also unavailable, the system will try the
third route. The dialing sequence for these routes needs to be the same from the user perspective,
as fallback occurs automatically and is not controlled by the user. If all three routes fail, the default
normal route is used.

illustrates the Alternate Routes panel.
