<p>First, most of the module functions return negative or positive
integer values, not boolean. You have to check with <0 for
what's usually false in native kamailio.cfg if conditions and
>0 for true.<br>
</p>
<p>Then, also double check it does not execute it via a different
config path, like the branch route callback (which happens in the
default native kamailio.org).</p>

<p class="MsoPlainText">Ok so making progress but still a little
confused, hopefully this forum can shed some light on this
behaviour.<br>
<br>
Using the hints provided (thanks all so far) and the latency
logging from the cookbook I have managed to isolate the issue
down to RTPengine introducing the delay.<br>
<br>
<span style="font-family:"Courier New"">INFO:
app_python3 [apy_kemi.c:1820]: sr_apy_kemi_exec_func():
alert - action KSR.rtpengine.rtpengine_manage(...) took too
long [1003089 ms] (<a class="moz-txt-link-freetext" href="file:(null)">file:(null)</a> func:(null) line:252)</span><br>
<br>
What is confusing is, I don’t believe this block should be
being called.<br>
<br>
when the BYE is triggered, it routes to <span
style="font-family:"Courier New"">ksr_route_withindlg</span>
<br>
<br>
<span style="font-family:"Courier New""> #
handle requests within SIP dialogs<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="font-family:"Courier

<br>
<br>
from within the <span style="font-family:"Courier

if any RTPengine work needs doing<br>
<br>
<span style="font-family:"Courier New""> # Handle
requests within SIP dialogs<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="font-family:"Courier

<p class="MsoPlainText"><span style="font-family:"Courier

<br>
<br>
RTPengine is configured in a way to step in whenever there is
an SDP present based on
<span style="font-family:"Courier New"">Content-Type:
application/sdp</span><br>
<br>
<span style="font-family:"Courier New""> #

<p class="MsoPlainText"><span style="font-family:"Courier

<br>
<br>
What I can understand is why is this being called and erroring
introducing the delay when there is no
<span style="font-family:"Courier New"">Content-Type:
application/sdp</span> in a BYE ???<br>
<br>
<br>
As a quick fix I have put this in which stops the problem (I
am sure there is better ways to handle this but for now this
works in a DEV environment)<br>
<br>
<span style="font-family:"Courier New""> def
ksr_route_rtpengine(self, msg):<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="font-family:"Courier
New""> if KSR.is_BYE():<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="font-family:"Courier
New""> return 1<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="font-family:"Courier
New""><o:p> </o:p></span></p>
<p class="MsoPlainText"><span style="font-family:"Courier
New""> if
KSR.textops.has_body_type("application/sdp"):<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="font-family:"Courier
New""> KSR.rtpengine.rtpengine_manage(<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="font-family:"Courier

New""><o:p> </o:p></span></p>
<p class="MsoPlainText"><span style="font-family:"Courier
New""> return 1</span><br>
<br>
Can anyone see why this would occur? Why is <span
style="font-family:"Courier New"">
sr_apy_kemi_exec_func(): alert - action
KSR.rtpengine.rtpengine_manage(...)</span> even being called
for this BYE ? when there is no
