Dialed Number Analyzer (DNA)

A CUCM serviceability tool that simulates digit analysis to show how a dialed number would be routed for a given CSS.

Definition

DNA lets administrators enter a calling device, calling number and dialed digits, then shows the matched pattern, partition, digit manipulations and final route. It helps diagnose routing issues without placing test calls. It must be activated as a service before use.

Example

DNA reveals that 9011 numbers match a blocking pattern in the line CSS before reaching the route pattern.

Exam tip

Use DNA to verify dial plan behavior; it does not test the actual network path.
