<p>Hello,</p>
<p>you hve to provide the sip traffic for this case, the screenshot
doesn't show the sip headers used for routing in this case,
therefore grab the sip traffic for all sip messages in such
scenarion, either ngrep output or pcap file, and send it over to
see if some headers are missing or not set properly.<br>
</p>
Cheers,<br>
Daniel<br>

<div>I have this problem with call transfer, may be someone
can help.</div>

<div>The phone to the far right is registered with the
Registrar to the far left using two PATH headers
(trespassing two proxy ports, 5070 then 5060).</div>
<div><br>
</div>
<div>As you can see in the graph below, after receiving the
UPDATE request, Kamailio relays it further from port 5060,
I expect it to be from 5070 just like the dialog forming
INVITE and the CANCEL afterwards.</div>
