<p>Yes, I did added it, means it was there, but
is_first_hop() was blocking adding it. I think it's some
leftovers from default config.</p>
<p>So, my conclusion, that is_first_hop() is ok with IP
addresses, but not ok with FQDN in route. Although FQDN is
added as alias<br>

<p>Then the problem is that you do not do
nat-traversal-like processing for
websocket/webrtc traffic. You have to use
set_contact_alias() + handle_ruri_alias()

<p>In a case if in

IP address of Kamailio present,

<p>I've tried to play with <b>record_route_preset("...")</b>

moz-do-not-send="true">https://skalatan.de/de/blog/kamailio-sbc-teams</a>)
with FQDN, but no luck.</p>
<p>Also wanted to try approach
using record_route_preset()
function in branch route, but it
was working only with first
branch, not affecting others
(but I assume having different
RR headers across branches is
not a good idea)</p>
