David,
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.
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

Did you add the handle_ruri_alias() as suggested by Daniel? I had
something like this where I would get “unable to resolve blah
blah blah" and it’s because the RURI is the actual wss “address”
which is unresolvable, so executing the function forces kamailio
to take the alias instead.

Daniel,
Seems to be it's really the case, but with other function
With FQDN in RR
|is_first_hop()|
is not acting correctly for reply.
For incoming SIP replies, it means that top Record-Route URI
is 'myself' and source address is not matching it
But in Record-Route we have "myself", but *is_first_hop()*
returning 0.
Thanks!

OK, because looping was something that should not have
happened in this case.
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() because the webrtc
endpoints do not set "valid" contact addresses.
Cheers,

This just is not sent with "unable to resolve address

Sorry. Looping were something else during my tests, this
just with *advertise* added

Yes, it is.

Also tried with

same behavior, loose_route() stops acting correctly.

Hello,
I saw there are some topics on this already and
carefully walked through all of them, but can't solve
following issue.
For a reason I do need that in Record-Route header
sent to endpoint would present FQDN. If it matters,
it's UDP/WSS conversion done on Kamailio.
So, scheme is quite simple
Enpoint A ->UDP-> Kamailio ->WSS-> Endpoint B (NAT)
Main issue here, that if in Record-Route headers it's
FQDN, but not IP addresses, on a new transactions
with a dialog (ACK on 200, PRACK, BYE),
Kamailio*loose_route()* function resolves address of
destination not current dialog, but actual R-URI (or
itself, if R-URI is something from WebRTC world) that
is not correct due to NAT.
If in RR headers IP addresses are present - all is
working as expected.
As an example (RR with FQDN)
B answers 200
SIP/2.0 200 OK

And Kamailio on *loose_route()* loops ACK to itself.
(with result of function == 1)
In a case if in Record-Route/Route headers just IP
address of Kamailio present, all works as expected,
but it's not really behavior I want to achieve.
I've tried to play with *record_route_preset("...")*
specifying only WSS part (as suggested in
https://skalatan.de/de/blog/kamailio-sbc-teams
<https://skalatan.de/de/blog/kamailio-sbc-teams>)
with FQDN, but no luck.
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)
