Troubleshooting Calling Search Space Issues

A.

When troubleshooting a voice network for call setup issues related to calling search space, the support engineer should investigate the CallManager traces.

A calling search space is a set of partitions that define the reachability of phone numbers or directory numbers. When a call is made, the calling search space is used to determine which partition to search for the called number. If the called number is not found in the partition, the call setup fails.

CallManager traces contain detailed information about call setup and routing. They can be used to troubleshoot issues related to calling search space because they show the calling and called numbers, the calling search space used to route the call, and any errors or failures that occurred during call setup.

CTI Manager traces are used to troubleshoot issues related to CTI applications and services, such as Cisco Unified Communications Manager Attendant Console or Cisco Unified Communications Manager CTI applications.

Cisco IP Manager Assistant is a web-based tool used to manage Cisco Unified Communications Manager. It does not provide trace files that can be used for troubleshooting call setup issues related to calling search space.

Call logs may contain information about calls made and received, but they do not provide the level of detail needed to troubleshoot calling search space issues. Call logs generally show the calling and called numbers, the date and time of the call, and the call duration.

In summary, the CallManager traces should be investigated when troubleshooting call setup issues related to calling search space.
