VQMon Reports

You can enable three types of voice quality reports:
  • Alert—Generated when the call quality degrades below a configurable threshold.
  • Periodic—Generated during a call at a configurable period.
  • Session—Generated at the end of a call.

You can generate a wide range of performance metrics using the parameters shown in the following table. Some are based on current values, such as jitter buffer nominal delay and round trip delay, while others cover the time period from the beginning of the call until the report is sent, such as network packet loss. Some metrics are generated using other metrics as input, such as listening Mean Opinion Score (MOS), conversational MOS, listening R-factor, and conversational R-factor.
