Route Pattern

The route pattern identifies a dialed number (E.164 numbers in North America)

and uses the underlying route list and route group configurations to determine

how to route the call. A route pattern can be entered as a specific number or, more

commonly, a number range. Using a route pattern to represent a number range

minimizes the number of entries required.

When a route pattern matches a dialed number, the call is handed to the route list

associated with the route pattern. Prior to handing the call to the route list, digit

manipulation can occur if digits need to be added to or removed from the matched

route pattern. The route list then decides which downstream route groups (trunk

groups) should receive the call based on the ordered priority.

Note The digit manipulation occurs in the route pattern for outbound calls

only, before being sent to the route list plus route groups. Individual

downstream route groups can have unique digit manipulations for

the same route pattern. This is extremely useful where different

routes to a given dialed number might require different

manipulations. For example, users might be required to dial seven

digits to reach a remote location that has a four-digit internal dial

plan. Across the IP WAN the first three digits would have to be

removed, so that the last four digits could be delivered to the remote

Cisco CallManager in its native internal dial-string length. If the IP

WAN were down or could not accept additional voice calls, the

dialed seven digits would have to be prepended with the area code

to reach the called party through the PSTN. A route pattern is

associated with only one route list.
