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.
<p>My kamailio.cfg configuration file can be downloaded from this
