The RTP analysis function takes the selected RTP stream (and the reverse
stream, if possible) and generates a list of statistics on it.
</p><div class="figure"><a name="idp35034772"></a><p class="title"><b>Figure 9.1. The "RTP Stream Analysis" window</b></p><div class="figure-contents"><div><img src="wsug_graphics/ws-tel-rtpstream-analysis.png" alt='The "RTP Stream Analysis" window'></div></div></div><br class="figure-break"><p>
Starting with basic data as packet number and sequence number, further
statistics are created based on arrival time, delay, jitter, packet size,
etc.
</p><p>
Besides the per packet statistics, the lower pane shows the overall
statistics, with minimums and maximums for delta, jitter and clock skew.
Also an indication of lost packets is included.
</p><p>
The RTP Stream Analysis window further provides the option to save the RTP
payload (as raw data or, if in a PCM encoding, in an Audio file). Other
options a to export and plot various statistics on the RTP streams.
