<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>
<p>Cheers,<br>
Daniel<o:p></o:p></p>

<p>Hello,<o:p></o:p></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.<o:p></o:p></p>
