Thank you for your reply Sergiu.

32 seconds is the default asterisk T2 timer. Probably some ACK is not
being relayed following BYE.
Would help to see some sip traces.

Hello everyone,
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.
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.
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.
Production scenario.
PSTN <----------> Dialer --------->kamailio -----------> asterisk1
-----------> asterisk2
Test scenario.
sipp generated calls ------> kamailio -------> asterisk1
-------> asterisk2
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:
/[Apr 25 17:49:59] WARNING[2121]: chan_sip.c:4072 retrans_pkt:
Retransmission timeout reached on transmission
[email protected] <mailto:[email protected]> for seqno 1
(Critical Response) -- See
https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions//
//Packet timed out after 31999ms with no response/
In the sipp panel I see in the Retransmission column several
incrementing counters, as per the attachment.
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.
My kamailio.cfg configuration file can be downloaded from this

Thank you very much.
