<blockquote type="cite"> Hello everyone,<br>
<br>
I have an error that I have not yet been able to
solve and would like the help of colleagues to
indicate a correct path.<br>
The problem that is occurring is that when the
client disconnects the call kamailio is not sending
the BYE forward until arriving at the asterisk.<br>
<br>
Both in the test scenario and in the production
scenario the problem is the same and the message I
see in the capture is 404 Not here, msg this coming
from kamailio.<br>
<br>
Production scenario.<br>
<br>
PSTN <----------> Dialer --------->kamailio
-----------> asterisk1<br>
-----------> asterisk2 <br>
<br>
Test scenario.<br>
<p>sipp generated calls ------> kamailio
-------> asterisk1</p>
<p>
-------> asterisk2</p>
<br>
<br>
When this occurs, the calls that are disconnected by
the client are in a "zombie" state in asterisk, and
end up being terminated by timeout with the
following message in the asterisk CLI:<br>
<br>
<font size="-1"><i>[Apr 25 17:49:59] WARNING[2121]:

<br>
In the sipp panel I see in the Retransmission column
several incrementing counters, as per the
attachment.<br>
<br>
If I take the kamailio from the move and point the
sipp to only one of the asterisk, the
retransmissions do not happen and BYE follows
normally.

downloaded from this url: <a class="m_-8861300085044965981m_834132679588246420m_3548078539755489536moz-txt-link-freetext" href="https://drive.google.com/file/d/1bBj4GEZSPrp1iJXSLWQ4Z6g59tEFjnNT/view?usp=sharing" rel="noreferrer noreferrer" target="_blank">https://drive.google.com/file/<wbr>d/<wbr>1bBj4GEZSPrp1iJXSLWQ4Z6g59tEFj<wbr>nNT/view?usp=sharing</a></p>
