An engineer must run a CUCM report on the number of local calls with poor voice quality. Which report type provides this information*?

The QoS by Gateway report aggregates voice quality data per gateway device, not per call classification type.

The QoS Detail report provides per-call quality records for individual calls but does not segment or summarize results by call type such as local.

The QoS by Call Types report in the Cisco Unified CDR Analysis and Reporting (CAR) tool specifically categorizes calls by type - including local, long distance, on-net, and off-net - and reports MOS scores, jitter, latency, and packet loss per category. This allows an engineer to filter and view poor voice quality data specifically for local calls, which no other QoS report type supports directly.

The QoS Summary report gives a high-level overview of overall QoS across all calls without breaking down results by call type.
