Benefits of Dialed Number Analyzer The Cisco DNA is a diagnostic tool within CUCM that enables administrators to validate and troubleshoot dial plan configurations by simulating call routing and providing a detailed analysis of how calls are processed. This ensures the accuracy and efficiency of voice communications within an organization. Validation of Dial Plan Configuration Dialed Number Analyzer allows administrators to test and verify that the dial plan is configured correctly without having to make actual calls. This can be useful when setting up or making changes to the dial plan, as it helps ensure that calls are routed as intended based on the current configuration. Troubleshooting and Diagnostics When issues arise with call routing or number patterns, Cisco DNA can be used to simulate calls and determine how the system is treating different dialed numbers. This aids in diagnosing problems and identifying misconfigurations or policy violations within the call-routing logic, which can save time and reduce the impact of dial plan issues on end-users. Detailed Analysis and Reporting The Dialed Number Analyzer provides detailed reports on how calls would be handled by the system for any given dialed number. These reports include information such as which route patterns are matched, which calling search spaces are used, and which translation patterns affect the call. This level of detail is valuable for both routine audits and for planning changes to the dial plan, as it helps administrators understand the intricate workings of their call-routing infrastructure. How to Enable and Access Dialed Number Analyzer In order to enable Dialed Number Analyzer, you need these steps: Note: Unified Communications Manager clusters only: Cisco does not recommend that you activate the service on all the servers in a cluster. Cisco recommends that you activate this service only on one of the servers of a cluster where call-processing activity is the least.
