<p>Hello,</p>
<p>just to clarify -- did you tried and there were some issues, or
just pure validation of the regex in the subst?</p>
<p>If the second, I would rather use subdt_hf(), but not sure it's
in 4.3 or added later. Then instead of \2, I would use $tU (To
header username).</p>
<p>Likely you can also completely avoid substitution operations, by
doing:</p>
<p>remove_hf("To");</p>
<p>insert_hf("To: <a class="moz-txt-link-rfc2396E" href="sip:$tU@$rd:rp"><sip:$tU@$rd:rp></a>;tag=$tt\r\n");<br>
</p>
Cheers,<br>

I need a sanity check if you don’t mind…  I am setting up a
stateless proxy for several (separate, not load balanced) Asterisk
servers behind Kamailio 4.2 (with domain and dispatcher). Â All
works as expected except when called party hangs up, as Asterisk
seems to address the BYE “To†(that is sent to the calling party)
to the originating domain, and not the IP of the UA (as it does in
other cases). Â When this happens, stateless Kamailio does not seem
to know how to route them, which makes sense. Â I assume I would
need to rewrite the “To†field on BYE message so that it contains
the UA’s IP (to match the BYE’s that are routed correctly).  The
RURI header contains the IP/port of the UA, so I am attempting to
use it and here is where I am stuck…
