Which component determines where a call can route?

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

Answer: (D)

In a call routing setup, the destination is determined by the Route Pattern. When you dial a number, the system compares the digits against Route Patterns and the one that matches tells CUCM where to send the call by pointing to a Route List (which defines the next hop, such as a gateway or trunk). Translation Patterns can alter the dialed digits before routing, but they don’t decide the final destination themselves. Route Lists come into play after a Route Pattern has matched, specifying the order of possible paths. Line Groups are for organizing line appearances and don’t control routing. So the Route Pattern is what determines where a call can route.
