When you define call routing, you can also instruct the system to perform
pretranslations (digit manipulations). Both destination routes and timed
routes have digit manipulation operations (append, prepend, replace,
stripLead, or stripTrail).
The system passes dialed digits first through the device's Least Cost
Routing table (if there is one). If the system finds no entry there, it then
uses the Normal dial plan table. If it does find an entry in the Least Cost
Routing table, it attempts to use that entry and, even if the attempt is
unsuccessful, it does not use the Normal table.
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

when met, result in a particular destination route being selected.
