<p class="MsoNormal"><span style="color:blue">Hi,<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:blue"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="color:blue">Am Agalya and we are using opensips for our project and using “<b>siptrace”
</b>module to trace and duplicate the sip packets to another server. <u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:blue">When trying to do so, am getting the below error.<u></u><u></u></span></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal"><span style="color:red">Mar 2 14:48:21 poc-opensip-cmc-e-001 /usr/local/sbin/opensips[27754]: DBG:siptrace:trace_onreq_in: trace on req in<u></u><u></u></span></p>

<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal"><span style="color:blue">I thought adding <b>“traced_user_avp”</b> parameter might solve the issue. I have added the below line and tested the same.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:blue">But I didn’t get through the error and was still seeing the same error.<u></u><u></u></span></p>
<p class="MsoNormal"><i><span style="color:blue">modparam("siptrace", "traced_user_avp", "$avp(traced_user)")<u></u><u></u></span></i></p>
<p class="MsoNormal"><span style="color:blue"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="color:blue">As a workaround, I commented the below lines in
<b>“siptrace.c”</b> file in function <b>trace_onreq_in()</b>, and it worked for me.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:blue">Packets are sent to another server. Following the same I have commented the same line of code wherever it is failing for me.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:blue">By adding some debugging statements I found
</span><b><span style="color:red">AVP is NULL and (!flag_trace_is_set(msg)) returns 1</span><span style="color:blue">.</span></b><span style="color:blue"><u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:red">/*if( (avp==NULL) && !flag_trace_is_set(msg))<u></u><u></u></span></p>

<p class="MsoNormal"><span style="color:red"> return;<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:red"> }*/<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:blue"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="color:blue">Query : What is avp? And when avp is returned NULL?
<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:blue"> What should I do in order to avoid that error without commenting the code?<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:blue"> Why is “traced_user_avp” parameter is used in config file?<u></u><u></u></span></p>
<p class="MsoNormal"><span style="color:blue"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="color:blue">It would be great if you help me to come out of this issue. Also am curious what causes this error message.<u></u><u></u></span></p>
