Quality for meetings is displayed based on the “worst-case” quality of the call for each participant in the meeting – in other words, the participant with the worst packet loss and/or jitter values dictates the overall meeting quality displayed. We do this in order to help vAnalytics users quickly identify call quality issues and to accelerate the troubleshooting process.
There are multiple ways to analyze quality issues more deeply. You can view all individual calls legs that are currently experiencing bad quality on the Active Calls tab in vAnalytics Real Time, as in the screenshot below.
If a call is using VMR/bridge technology, you can view the entire meeting on the Active VMRs tab in vAnalytics Real Time module. If you click on the VMR name or to expand the details, you can view all the participants in that meeting and the quality they are currently experiencing.
You can see similar data in Advanced Analytics under the Meetings tab. You can click on the Meeting name to expand the participants and their quality experience.
For more details, you can switch views in the Meetings tab to dig down into a specific participant’s call quality. By switching to the Participants view in the example above, we can take a closer look at Jeff’s meetings where call quality was bad. We’ll grab his email from the exposed participants in the previous view and set it equal to the Participant Address. Then we can filter the view to just the calls where there was bad quality.
This will expose the Stream Types for Jeff’s calls (inbound and outbound Audio and Video, as well as Presentation). For those streams, you’ll see their quality rating, Average Jitter, Average Packet Loss (%), and additional details.
