<p>Hello,</p>
<p>looking at the trace, the routing is parallel forking, because
the two branches are sent out at the same time, it is no final
response to the first branch before the second is sent out.</p>
<p>Are you sure you sent out the second branch from failure route?
From the sip trace is doesn't seem so.</p>
<p>Cheers,<br>
Daniel<br>

<p>Can you get a ngrep trace captured on kamailio server for
such situation?<o:p></o:p></p>
<p>Also, can you paste the failure_route block here along with
the log messages from the syslog?<o:p></o:p></p>
