Although not easy on a production system, your best bet is to catch the behavior in the act. Usually this means that you have to rely upon humans to report the symptoms to you in a timely and accurate manner. <div><br></div>
<div>One way you can help track these down is to use something like pcapsipdump and do a ring buffer that covers at least several days. Then, when you hear about a symptom you can go back and look at the corresponding pcap file which will have both signaling and audio. From there you can hopefully trace the root of the problem.</div>

<p><u></u><span>1.<span style="font:7.0pt "Times New Roman"">
</span></span><u></u>NORMAL_TEMPORARY_FAILURE happens a lot, and often
returns 30 or more seconds after starting. Could this be a “silent call”
(etc)? We have gotten 3-4 complaints of silent calls and I’m hoping to
find the cause.<u></u><u></u></p>
<p><u></u><span>2.<span style="font:7.0pt "Times New Roman"">
</span></span><u></u>Is there anything here (or ideas elsewhere?) to explain
why a call will be silent once in a while?<u></u><u></u></p>
<p><u></u><span>3.<span style="font:7.0pt "Times New Roman"">
</span></span><u></u>Is this spread of causes normal or does it seem strange<u></u><u></u></p>
<p><u></u><span>4.<span style="font:7.0pt "Times New Roman"">
</span></span><u></u>We’ve had a few people note that the message on
their voicemail is over before they can hear it - even though we play the
message twice (to make short messages longer). Does anybody know of a solution
for this?<u></u><u></u></p>
