What is this about?
We noticed that your session experienced some fluctuations in the media. Based on the
specific message you received, this is either about incoming or outgoing media, and
related to audio or video:
| Code | Direction | Media type |
| 4200 | Incoming | Audio |
| 4201 | Outgoing | Audio |
| 4210 | Incoming | Video |
| 4211 | Outgoing | Video |
Fluctuations in the media occur when the values measured for media quality metrics (packet loss, jitter, and round-trip time) are noticeably higher than the average measurement.
The message notification also includes the time within the session that these issues
were noticeable, giving you a better idea as to the extent of the issue.
Note: If the erratic behavior also breaches the
error threshold of the given metric, then it will be marked as an error instead
of a warning.
Potential risks
For sessions that are quite long, the average quality metrics can be misleading – they can show results that seem good while hiding behind them momentary spikes in the metrics which can indicate media quality issues.
Suggested actions to take
-
Look closer at the data and see if this makes sense
-
Correlate the timing of the poor measurements with infrastructure side metrics to see if this is a client-side issue or a server-side issue
