Call routing with Unified Communications Manager can become quite complex and intricate; when faced with dial plan related problems, the Dialed Number Analyzer can provide insight.
The Dialed Number Analyzer is a complex and involved tool, this recipe will try only to introduce its use. To learn more about this powerful tool, I recommend reading the Cisco Unified Communications Manager Dialed Number Analyzer Guide (http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/dna/8_0_1/dnaguide.pdf) for more comprehensive coverage.
This recipe requires the Dialed Number Analyzer services be activated; if it has not already been activated, perform the following:
First log into the Unified Serviceability page (
https://cucm:8443/ccmservice
).Navigate to the Service Activations page (Tools | Service Activation).
Activate the Cisco Dialed Number Analyzer Server and Cisco Dialed Number Analyzer services.
