Hello,<br>
<br>
you should enforce specific routing only for initial INVITE. Along
with that do record_route() and for requests within dialog use
loose_route() + t_relay() in order to keep the same path of
singaling for same dialog.<br>
<br>
If you look at the default kamailio.cfg, it uses the record routing
mechanism, which is the standard for routing requests within dialog.<br>
<br>
Cheers,<br>
Daniel<br>

<p class="MsoNormal"><span lang="EN-US">Hello,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I would like some advice
about a situation i have encountered recently. I’m using
Kamailio 4.3.4 as a “proxy” : I have a media server, and to
reach this server all the requests have to pass through my
Kamailio server. The Kamailio server does not have to handle
authentification or registration, all of that stuff is done
on the media server. To do that I’m using the following
route :
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">route[REDIRECT] {<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> if($rU
== "" ) {<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">
$ru = (<a class="moz-txt-link-rfc2396E" href="sip:1.2.3.4:xxxx">"sip:1.2.3.4:xxxx"</a>);<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">}<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"> else {<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">
$ru = ("sip:" + $rU + "@1.2.3.4:xxxx");<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">}<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">}<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">1.2.3.4 is my media
server’s address. I have 2 users : an “internal” one
registered on the media server, and an “external” one which
is a random caller. It works fine for EXT -> Kamailio
-> Media server requests but when I try to hang up with
my internal user, the “BYE” request uses the following path
: Internal user -> Media server -> Kamailio ->
Media server instead of : Internal user -> Media server
-> Kamailio -> External user. Obviously it is because
of the REDIRECT route which send back the “BYE” request to
the media server, when it should sends that request to the
external user.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">So, how should I modify
that route to do what I want ? Maybe should I create a
second route ? Any answer will be appreciated
</span><span style="font-family:Wingdings" lang="EN-US">J</span><span
lang="EN-US"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Best regards,<o:p></o:p></span></p>
