I like that cool Perl script. I&#39;ll have to try that some time. In the meantime you can use tshark to extract the rtp and then use sox to turn them into wav files. I&#39;m working on a script to do that automatically, but in the meantime this post should help:<br>

&gt; I&#39;ve have some really large PCAPs sometimes and wireshark just dies trying<br>
&gt; to decode the audio in them.<br>
&gt;<br>
&gt; All the links for audio extraction on voipinfo seem really old.<br>
&gt;<br>
&gt; Is there something else to extract the audio from pcaps? Or some command to<br>
&gt; to pass tshark to just save all audio as a .wav file?<br>
&gt;<br>
&gt; What does voipmonitor use?<br>
&gt; I think I asked this before...<br>

</div></div>How big are the pcap files ?<br>
<br>
you could use editcap to split them up into more manageable chunks,<br>
and then use wireshark...<br>
