Video Call QoE Test Report
You can collect video call metrics from the test report and analyze them to improve call quality. Quality metrics such as jitter, latency, packet loss, and video frame rate are displayed in addition to call details. This information is displayed for both participants in the call.
- On the Navigation bar, click . The Video Call QoE page is displayed.
- Click Test Call Name attribute. The Video Call QoE Test Report page is displayed.
The Video Call Report contains the following components:
- Participants Details table
- Zoom Call Statistics tile
Participants Details Table
The Participants Details table displays exhaustive information about the call, such as the client MAC address, participant name, IP address, network type, AP name, AP MAC address, SSID, radio frequency, join time, leave time, and Wi-Fi connection quality. You can select the MAC address of the client for the participants by clicking the Edit icon () in the Client MAC column. You can also pause the pointer over the status capsule in the Wi-Fi Connection Quality column for more information about RSS, SNR, throughput estimate, and average MCS (downlink). A video call of good quality is displayed as a green capsule with text "Good" in the Wi-Fi Connection Quality column, a poor quality call is displayed as a red capsule with text "Bad", and an average quality call is displayed as a gray capsule with text "Average". You must click the Select Client MAC icon, and select the client for each participant to view the Wi-Fi statistics.
To view the troubleshooting information, click AP MAC attribute. The Client Troubleshooting Page is displayed. For more information , refer to Client Troubleshooting page.
To view the AP details report, Click AP attribute. The AP Details Report page is displayed. For more information , refer to AP Details Report.
Zoom Call Statistics Tile
- Jitter: Displays jitters produced during the call in milliseconds (ms) for both participants for the duration of the call. The participant with lower jitter values experienced better call quality.
- Latency: Displays latency (delay) produced during the call in milliseconds (ms) for both participants for the duration of the call. The participant with lower latency values experienced better call quality because there was minimum or no delay in audio and video transmission.
- Packet Loss: Displays the percentage of data packets lost during video and audio transmission for both participants. The participant with lower values experienced better call quality because there was minimum or no data loss during audio and video transmission.
- Video Frame Rate: Displays the number of video frames transmitted and received between both participants during the call. If the video call was successful for both participants, these values will be the same. The participant with lower frames per second experiences poor video quality.
