To prevent toll fraud, an engineer can block certain patterns in Cisco Unified Communications Manager (CUCM). The two points where an engineer can block the pattern in CUCM are:
Route Pattern: A route pattern is a string of digits that matches the number dialed by a user. An engineer can block a particular pattern by creating a route pattern that prevents the call from being routed to the PSTN. By configuring a route pattern that matches the pattern used for toll fraud, the engineer can block the call from being placed.
Translation Pattern: A translation pattern is used to modify the digits of a dialed number before it is routed. An engineer can use a translation pattern to block a particular pattern by translating it to an invalid number. For example, the engineer can create a translation pattern that matches the pattern used for toll fraud and translates it to a number that does not exist, which will prevent the call from being routed to the PSTN.
In addition to these two options, an engineer can also use partitions and calling search spaces (CSS) to control access to certain patterns. A partition is a logical grouping of directory numbers, route patterns, and translation patterns that restricts access to those objects. A CSS is a list of partitions that a device can access, which determines which objects are available for dialing.
However, for preventing toll fraud, blocking route patterns and translation patterns is the most effective method.
