<p>Hello,</p>
<p>the new trace shows a serial forking, with the first branch
timing out, but the second branch is getting a 183 response, and
that's all. It is not the same scenario you described. I need the
full trace, from initial invite to the final response sent back to
caller to see what is the winning response code.</p>
<p>Cheers,<br>
Daniel<br>
