<p><span lang="EN-US">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.<o:p></o:p></span></p>
<p><span lang="EN-US">Are you sure you sent out the second branch from failure route? From the sip trace is doesn't seem so.<o:p></o:p></span></p>
