<div dir="ltr"><p class="MsoNormal">Hello,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I am trying to diagnose an intermittent error when a call
comes in over our PRI lines.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">The problem appears random, however I have feeling it
has something to do with the call volume, as the frequency increases with more
calls on the system.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I am not an expert when it comes to reading the PRI Span
Debug statements but here is a call that had a problem and I bolded,
italicized, and underlined the part of the debug statement that looks odd
(listed under PRI Debug Output (failed call)).</p><p class="MsoNormal"><br></p><p class="MsoNormal">Any help is appreciated.</p><p class="MsoNormal"><br></p><p class="MsoNormal">Thanks,</p><p class="MsoNormal">Bryce</p>

<p class="MsoNormal"><b> </b></p>
<p class="MsoNormal">When I have the problem, the only way I see that Asterisk
received a signal on my PRI lines was through the pri debug statements, I don’t
see anything being hit in the dialplan (for instance the NoOp at the start of
my sub-dial-cudatel-extension sub context). Is there another tool I
should be using to debug this issue?</p>
