Voice Quality Queries

Mitel Performance Analytics provides the following initial set of Voice Quality (VQ) queries under the Network Data > Voice Quality Queries menu. Additional queries can be configured with the Reports menu item. Refer to "Generating Reports".

To use these queries, you must enable the option to collect voice quality metrics in the device settings. Devices that support voice quality include:

MiVoice Business

MiVoice Business EX

MiVoice MX-ONE

MiVoice Border Gateway

MiVoice Connect HQ Server

MiVoice 5000

Query Name	Description
Bad calls in the last 30 days	This query displays brief details of all bad calls recorded in the last 30 days. The call quality is calculated based on the default R factor that you specified in the container settings (minimum, average, or maximum R factor). For more information, see "Configuring Containers".
Voice Quality by Hour of Day	This query displays VQ metrics for the hours of the day. Metrics include the number and percent of good, fair, poor, or bad call segments; the hour of the day they occurred, and the total number of call segments.
Worst Performing DNs (#)	This query displays the number of call segments with bad or poor quality for the worst directory numbers associated with a device. The call quality is calculated based on the default R factor that you specified in the container settings (minimum, average, or maximum R factor). For more information, see "Configuring Containers". The chart view displays up to a maximum of the worst 20 items.
Worst Performing DNs (%)	This query displays the percentage of poor quality call segments for the worst directory numbers associated with a device. The chart view displays up to a maximum of the worst 20 items.
Worst Performing Devices (%)	This query displays the number of call segments with bad quality for the worst devices in a container. The chart view displays up to a maximum of the worst 20 devices.
All Calls	This query displays an overview of all calls. You can use this query to assess the volume of calls that occur during a specified time range and filter the data according to the device type, the DNS involved, the SIP call IDs, and more. This query is available for MiVoice Business devices. If you deploy MiVoice Business devices in conjunction with a MiVoice Border Gateway, ensure that both devices are monitored by the same probe. Before you use this query, ensure that you configure the following settings: In the container where the device is located, enable Call Correlation in the container settings; see "Configuring Containers". Enable IP set inventory monitoring in the device settings for the MiVoice Business and MiVoice Border Gateway devices; see "Configuring Mitel Performance Analytics for MiVoice Business " and "Configuring Mitel Performance Analytics for MiVoice Border Gateway". After you enable these settings, wait 15 minutes for data collection before running the query.
VQ – All Data	This query displays an overview of all call segments recorded and the associated VQ metrics for each call segment. By default, only a day’s worth of data is displayed in the query. You can view the query by week or by month; however, because this query reads individual voice quality records from the database, selecting a longer time period results in longer processing times. By default, all the VQ data is displayed in the table view. You can group data within the table by dragging a column into the heading area. For example, you can group the data according the to MPA Call ID, which allows you to find call segments that had low R values and correlate them to the parties who were affected by poor call quality. You can also use this view to identify patterns in the occurrences of poor call segments. You can also choose one of the available shared views: Bad Calls by Department Bad Calls by Location Bad Calls by Subnet
