<p>Hello,</p>
<p>failure route is preserving the attributing of the branch that
received the failure reply.</p>
<p>You have to use resetdsturi() in this case -- see the readme of
kex module.</p>
<p>Cheers,<br>

Hello All,
<div class=""><br class="">
</div>
<div class="">We use registrar servers (call them A,B) for TLS
connections from clients and a central routing proxy (P) that
authenticates and manages all call routing.</div>
<div class=""><br class="">
</div>
<div class="">On INVITE, P uses lookup(“location”) and
handle_uri_alias() to route the INVITE to A or B depending on
the AOR from REGISTER.</div>
<div class=""><br class="">
</div>
<div class="">In failure_route I’m trying to send INVITE to a
voicemail URI at host (V), using alias_db_lookup to retrieve it
and sending with t_relay(). However, despite showing V as the
host in the URI, the message is sent to A (or B) as if the
handle_uri_alias is still in effect.</div>
<div class=""><br class="">
</div>
<div class="">I’ve tried calling revert_uri() before the
alias_db_lookup(), but this doesn’t seem to help. Is there a
way to reset the uri_alias?</div>
<div class=""><br class="">
</div>
<div class="">The failure_route (simplified) looks like this:</div>
<div class="">
<div class=""><font class="" face="Courier">failure_route[1] {</font></div>
<div class=""><font class="" face="Courier"> if (method
== "INVITE") {</font></div>
<div class=""><span style="font-family: Courier;" class="">
revert_uri(); </span></div>
<div class=""><span style="font-family: Courier;" class="">
if (alias_db_lookup("dbaliases")) {</span></div>
<div class=""><span style="font-family: Courier;" class="">
t_relay();</span></div>
<div class=""><font class="" face="Courier"> }</font></div>
<div class=""><span style="font-family: Courier;" class="">
}</span></div>
<div class=""><font class="" face="Courier">}</font></div>
</div>
<div class=""><br class="">
</div>
<div class="">I have also tried using t_relay(“$rd”, “$rp”) after
confirming (by logging) that the uri contains the desired
values, but kamailio failed to start, with this error logged:</div>
<div class=""><font class="" face="Courier"><span class="Apple-tab-span" style="white-space:pre"> </span>ERROR:
tm [tm.c:672]: fixup_hostport2proxy(): TM
module:fixup_hostport2proxy: bad port number <$rp></font></div>
<div class=""><br class="">
</div>
<div class="">Any suggestions?</div>
<div class=""><br class="">
</div>
<div class="">Best regards,</div>
<div class="">Dave.</div>
