<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] (file:(null) 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 New""> if self.ksr_route_withindlg(msg)==-255 :<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="font-family:"Courier New""> return 1</span><br>
<br>
<br>
from within the <span style="font-family:"Courier New"">ksr_route_withindlg</span> a check is done to see 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 New""> def ksr_route_withindlg(self, msg):<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="font-family:"Courier New""> if KSR.siputils.has_totag()<0 :<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""> # RTPEngine handling for UPDATES & reINVITES with sdp<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="font-family:"Courier New""> if self.ksr_route_rtpengine(msg) == -255:<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="font-family:"Courier New""> return 1</span><br>
<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""> # RTPengine handle anything with SDP<o:p></o:p></span></p>
<p class="MsoPlainText"><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.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""> "RTP/AVP replace-session-connection replace-origin ICE=remove")<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>
<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""> "RTP/AVP replace-session-connection replace-origin ICE=remove")<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
<span style="font-family:"Courier New"">Content-Type: application/sdp</span><o:p></o:p></p>
