<p>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().</p>

<div>Hello,</div>
<div><br>
</div>
<div>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).</div>

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:<br>
<br>
```<br>

```<br>
<br>
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.<br>
<br>
Could I have more information about the
"FIXME" tag?<br>
<br>
Thanks in advance!<br>
