I prefer this logic:

403...\n");
sl_send_reply("403", "out-of-dialog loose_route not allowed");
exit;
}
... loose..route..processing
... NAT traversal...rtpproxy....
t_relay();

Post the ngrep dump of the 2 different processes.
Furter use "ngrep udp" on the Kamailio/rtpproxy server to verify
RTP/UDPTL packet flows.

That's
strange. You shouldn't allow requests with totag but without
loose-routing. But that's not related to your problem.
Could that cause some problems for me? If it has totag and have a route
it should exit, else it should check if the current request is
associated to a request, if ok it should relay else exit.
How would you have written it? IMO the config is a bit strange but I
couldn't spot an error.
I'd really hoped for an error here. :\
Trace the scenario with ngrep and take a look at
the SDPs if they are
rewritten properly.
I'm not able to spot any errors, the only error I'm able to see is that
it seems to work one way.
If A sends a fax to B
This works with T.38:
asterisk A <-> sipprovider <-> our trunk <-> kamailio/rtpp <->
asterisk
<-> asterisk B (our asterisk)
This fails with T.38, but works with G.711:
asterisk B -> asterisk -> kamailio/rtpp -> our trunk -> asterisk ->
asterisk A
Could also be an Asterisk (A: 1.6.2.5/tested with 1.6.2.7rc, B: 1.6.2.6)
or FFA bug. But if I try to send the FAX directly via SIP from A <-> B
without the proxy everything works OK, so therefore I believe the
problem are related to my kamailio configuration.
Appreciate all the help I can get.
Espen.
