Route List Digit Manipulation Behavior in Cisco Unified Communications Manager

C.

In Cisco Unified Communications Manager (CUCM), a Route List is an ordered list of gateways or trunks used to route calls. When a call is made, CUCM uses the Route List to determine the best path for the call to reach its destination. Route Lists can have associated digit manipulation rules that modify the digits in the called and/or calling party numbers before routing the call.

Regarding the behavior of digit manipulation rules in Route Lists, the following options can be considered:

A. Digit manipulations occur once per route list: This statement is incorrect. Digit manipulations are applied at each individual Route Pattern within the Route List.

B. Called party transformations at route list level is reflected on the display of the calling phone: This statement is also incorrect. Called party transformations at the Route List level are not reflected on the display of the calling phone.

C. Called party transformations at route list level is replaced by called party transformations at route pattern level: This statement is incorrect. If there are digit manipulations applied at both the Route List and Route Pattern level, the digit manipulation at the Route Pattern level takes precedence over the digit manipulation at the Route List level.

D. Called party transformations at route list level is not shown on the display of the calling phone: This statement is correct. Called party transformations at the Route List level are not reflected on the display of the calling phone.

E. Only called party transformation is available at route list level: This statement is incorrect. Both calling party and called party transformations are available at the Route List level.

In summary, the correct description of Route List digit manipulation behavior in Cisco Unified Communications Manager is that digit manipulations are applied at each individual Route Pattern within the Route List, and if there are digit manipulations applied at both the Route List and Route Pattern level, the digit manipulation at the Route Pattern level takes precedence. Also, called party transformations at the Route List level are not reflected on the display of the calling phone, and both calling party and called party transformations are available at the Route List level.
