<font face="monospace">Hi Ali,<br>
<br>
yes, that's a bit of known issue - there is a conflict between the
point where the tracer modules grabs data versus the point where
the dialog module is doing the call-id changes :(<br>

<p class="MsoNormal">Hello All,<br>
<br>
I’m using Topology hiding module with “UCA” parameters and I’m
creating new call-id for outgoing leg(This is I can see from
SNGREP).
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">However, the Tracer module does not reflect
this. It logs both the inbound and outbound legs under the
original Call-ID, ignoring the new one generated by
topology_hiding(). My trace call is at the top of the main
route block:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> route {<o:p></o:p></p>
<p class="MsoNormal"> trace("tid");<o:p></o:p></p>
<p class="MsoNormal"> ...<o:p></o:p></p>
<p class="MsoNormal"> }<br>
<br>
<o:p></o:p></p>
<p class="MsoNormal">This creates a troubleshooting gap: when
correlating traces with downstream systems or with packet
captures, the Call-ID in the trace log does not match the
Call-ID that was actually sent to the outbound leg.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">1. Is this the expected behaviour of the
Tracer module when used alongside topology_hiding("UCA")?<o:p></o:p></p>
<p class="MsoNormal">2. Is there a way to make the Tracer log
the outbound leg under its real (rewritten) Call-ID?<br>
<br>
