Once you get the raw file out of the pcap do this:<br><br>sox -t ul -r 8000 -c 1 file.raw file.wav<br><br>That&#39;s assuming it&#39;s ulaw. Change &quot;ul&quot; to &quot;al&quot; if it&#39;s Alaw. If it&#39;s some other codec then you&#39;ll need to figure out how to convert the raw to wav. (That&#39;s where anthm&#39;s improvement of fs_encode is really handy.)<br>

&gt; I am presuming that the pcap contains multiple &quot;streams&quot;, so why not<br>
&gt; use a display filter to isolate and save each stream you are<br>
&gt; interested in,<br>
<br>
</div>I believe that pcapsipdump can do this as well - take a pcap and create<br>
per-call pcaps from it (SIP+RTP).<br>
