In CUCM, which element is essential for digit analysis and routing?

• A. Route pattern
• B. Partition
• C. Digit analysis and route selection based on CSS/partition
• D. Call detail record

Answer: (C)

In CUCM, how a dialed number is turned into a destination hinges on how digits are analyzed and how that analysis is filtered by access controls. Route patterns define how digits map to destinations, but the actual route that can be used depends on what partitions those patterns belong to and what partitions are accessible through the Calling Search Space. In other words, the system must both analyze the digits to pick a candidate route pattern and then select among those patterns based on CSS and partition permissions. That combination—digit analysis and route selection governed by CSS/partition—is what makes routing work correctly. Route patterns alone don’t account for access control, partitions alone don’t perform digit analysis, and call detail records aren’t used for routing decisions.
