The Call Quality Trend view provides an enterprise-level view of MOS (Mean Opinion Score) data from all calls detected during the selected timeframe.
MOS values do not apply to video streams. Network MOS is not included.
The trend chart does not include an indication of the number of call minutes used to derive the metrics. To determine the number of observations behind the trend, navigate to the CA Unified Communications Monitor data source and view the Call Performance Overview report. Click the Metric Details link at the top of the report.
Note: This view does not support data from multiple data sources. If you registered multiple instances of CA Unified Communications Monitor, edit the view to filter by one data source. Or change the dashboard group context by clicking the Group link. Using either method, you can select one data source in the Groups tree to serve as the view context.
