The place to get the final message is in onsend_route, being available in the $snd(buf).
That's when Kamailio figures out everything required for sending out (e.g., resolving NAPTR/SRV/CNAME/ANAME/... dns, doing mhomed processing to select local socket.a.s.o) and builds the appropriate headers like Via, Record-Route, ...
Cheers,
Daniel

I see, would it be possible to obtain the final message (with the generated Record-Route headers) somehow?
Thank you.

You have to use $mbu before record_route() because the outgoing socket is not known and corresponding Record-Route header is added with empty address. Same apply for use of msg_apply_changes().

It is also worth mentioning that there are two Record-Route headers, the first one is the correct one and contains a valid value, and this extra one which does not appear in the egress INVITE in the pcap.

Hello Daniel,
I have just realized about an error in the 'Record-Route" header: "Record-Route: <sip:;r2=on;lr=on;ftag=478.0eb>".
Thanks for the response.

Hello,
in onsend_route the changes are already applied, use of $mbu makes no sense there -- you can see the updated buffer content with $snd(buf).
Cheers,

Hi,
I'm getting some CRITICAL logs when accessing the content of the $mbu pseudovariable in a "onsend_route" function. The log lines look like this:
```
CRITICAL core 35847:core/msg_translator.c:493 null send socket

```
I've checked the msg_translator.c source file and there are many of `LM_CRIT("FIXME: {message}\n");` calls, and I wonder if the "FIXME" tag relates to the location of the error: a Kamailio error or there is an issue in the user code.
Could I have more information about the "FIXME" tag?
Thanks in advance!
