Just as a note: If you need to record_route for in-dialog requests then
the clients are buggy and you should report the issue.

Hello,
In our network topology we use Kamailio at the edge of our network proxying
requests from a core set of FreeSWITCH servers.
I have a new termination provider where a session timer ReINVITE fails because
the ACK is sent to the contact address of the FreeSWITCH server, not the proxy.
Can I Record-Route these in dialog requests? If so, where should I do it in
the config?
A quick google search returned this thread:
https://lists.cs.columbia.edu/pipermail/sip-implementors/2003-June/005089.html
which confused me a little.
yes, you can re-enforce record route for requests within dialog, although not
required by specs. See below the position.
My in dialog config block looks like this:
# Handle requests within SIP dialogs
route[WITHINDLG] {
if (has_totag()) {
# sequential request withing a dialog should
# take the path determined by record-routing
if (loose_route()) {
Add it after the above line, like:
record_route();
if (is_method("BYE")) {
setflag(FLT_ACC); # do accounting ...
setflag(FLT_ACCFAILED); # ... even if the transaction fails
setflag(FLT_SIPTRACE);
}
if (is_method("ACK")) {
# ACK is forwarded statelessy
route(NATMANAGE);
}
route(RELAY);
} else {
if ( is_method("ACK") ) {
if (t_check_trans()) {
# no loose-route, but stateful ACK;
# must be an ACK after a 487
# or e.g. 404 from upstream server
t_relay();
exit;
} else {
# ACK without matching transaction ... ignore and discard
exit;
}
}
sl_send_reply("404","Not here");
}
exit;
}
}
Cheers,
Daniel
