Which entity aggregates several Route Groups into a single outbound route?

• A. Route Pattern
• B. Route List
• C. Translation Pattern
• D. Line Group

Answer: (B)

Outbound routing in CUCM is organized so a single outbound path is defined by a Route List that gathers several Route Groups. The Route List is what you attach to a Route Pattern to specify the overall outbound route for a dialed destination. Each Route List contains multiple Route Groups in a defined order, so the system can try them in sequence to reach a reachable endpoint. Inside a Route Group, the actual endpoints are defined via Line Groups, which contain the trunks or lines that can be used to place the call. So the Route List is the container that aggregates multiple Route Groups into one outbound route.

The other elements play different roles: a Route Pattern matches digits and selects the Route List; a Translation Pattern modifies dialed digits; and a Line Group is simply a collection of lines or endpoints used within a Route Group.
