Last Calls Tab

In this tab, all calls detected in the selected time interval are shown. These calls were reconstructed from VOIP flows. Incomplete calls are also listed.

If you click a call, a dialog box with call details opens. It shows information about calling and called parties, call times, used codecs, call quality (reported by RTCP and measured by the probe), and so on.

RTP jitter is measured in RTP timestamp units. The RTP timestamp unit is based on the sampling rate. For example, for the sampling rate of 8000 Hz (PCMA) one unit is equal to 1/8000 of a second. For details, refer to RFC 3550 - interarrival jitter.
