Silence detection feature
VoIPmonitor is able to detect (currently only for G711a/b) silence in the RTP stream. It must be enabled in voipmonitor.conf (silencedetect = yes). When enabled those metrics are produced:
- Percentage of silence in each direction of a call which will be shown in cdr detail
- number of silence seconds from the end of the last RTP packet - this might be the reason why someone hanged up the call. If value is non zero it will be shown also in CDR summary:
- Number of clipped frames - those are with the highest volume - perceived as audible clicks - this value is shown in cdr detail table. It can be filtered and used in charts
CDR detail
Data series in charts for silence, silence end and clipped frames.
