<p>Hello,</p>
<p>408 has priority over 486, being a lower value. If you add the
second branch in a branch-failure-event-route, then you have
parallel forking and the lowest code is selected.</p>
<p>Anyhow, from your sip trace, it seems that the 486 was forwarded,
not local generated, because it has the to-tag from callee side.
The 408 is generated by kamailio.</p>
<p>Maybe you can enable cfgtrace for debugger an see what actions
are executed, to be sure it runs over the config parts you expect
to.<br>
</p>
<p>Cheers,<br>

<p>Hello,<o:p></o:p></p>
<p>do not send replies in branch failure route. At that phase,
the outgoing branches are not yet completed. More important,
do not use sl_send_reply() (this sends a stateless reply)
after the transaction has been created (which is the case of
branch failure route or failure route), use t_reply() if you
are sure that transaction was created or send_reply() if you
are not sure (so this option is the safest). Sending a
stateless reply when a transaction is active doesn't have any
effect on transaction state and tm module will send its own
reply once it considers the transaction to be completed.<o:p></o:p></p>
<p>Also, creating a new branch in branch failure route
(event_route[tm:branch-failure:...]) adds to parallel forking.
Serial forking is done only from failure_route[...], when all
branches sent out before were completed.
<o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:12.0pt">Hope these are
clarifying the behaviour you get there.<br>

<p>Hello,<o:p></o:p></p>
<p>your latest sip trace shows that 486 is sent out to caller
(the acc record from syslog shows that the transaction was
completed with that code as well). An ACK follows, but then
I see also 408.<o:p></o:p></p>
<p>Can you check you config and see if there is some other
place that can generate the reply, like a send_reply(...) or
t_reply(...)?<o:p></o:p></p>
