This article tells about the Dialed Number Analyzer in Cisco Unified Communications Manager (CUCM). Why do you need it? Suppose you are configuring a complicated dial plan on your server. There are CSS, Partitions, Route Groups, Route Lists, Route Patterns, etc. How should you test it to find mistakes? Here comes the Dialed Number Analyzer. It helps you to analyze a dial plan and gives the full call flow information for the dialed digits.
First of all, proceed to the Cisco Unified Serviceability menu → Tools → Service Activation. Now check Cisco Dialed Number Analyzer and click Save.
Now proceed to Tools → Dialed Number Analyzer, or open the following URL: https://[cm-machine]/dna. In the window that appears, open Analysis → Analyzer.
Here you should fill out three fields:
- Calling Party – the caller’s phone number for the test call;
- Dialed Digits – the dialed digits;
- CSS – Calling Search Space for the test phone.
After that, click Do Analysis. You will see what happens to a call under the specified conditions.
To analyze gateways, phones and trunks separately choose Gateway, Phone or Trunk in the Analysis menu.
