You can tcpdump and then use wireshark to graph the calls.&nbsp; When the dump is displayed in wireshark, select &#39;Statistics&#39; -&gt; VoIP Calls.&nbsp; You will see a display of all VoIP calls.&nbsp; Select the one you want graphed, or select them all and you will see REINVITE and REFER interaction as well as RTP streams.<br>

you could try sippcapdump but i hear it needs work but it snoops the wire and tries to make individual files out of each call.<div><div></div><div class="Wj3C7c"><br><br><br><div class="gmail_quote">On Fri, Feb 20, 2009 at 9:27 AM, kokoska rokoska <span dir="ltr">&lt;<a href="mailto:kokoska.rokoska@post.cz" target="_blank">kokoska.rokoska@post.cz</a>&gt;</span> wrote:<br>

Shelby Ramsey napsal(a):<br>
<div>&gt; Why not just use NGREP and then dump the packets at a more reasonable<br>
&gt; pace?<br>
<br>
</div>Thank you very much, Shelby, for your interest!<br>
<br>
I can&#39;t use ngrep because the dump is not searchable IMO :-)<br>
See below, please.<br>
<div><br>
&nbsp;You aren&#39;t going to be able to analysis in real time anyway.<br>
&gt;<br>
<br>
</div>Some basic diagnosis should by doable realtime. For example:<br>
1. find whole SIP trace for selected call (both a-leg, b-leg)<br>
2. find all succeful user REGISTERs for given period<br>
...<br>
<br>
And I have no idea how to do it on 50-100 GiB plain text file.<br>
