[OpenSIPS-Users] Load balancer - how to not change origination ip

Salutare Bogdan,
I do exactly the tutorial routing. Yes there is a t_relay() at the
end and one after loose_route().
if (!has_totag()) {
# initial request
record_route();
} else {
# sequential request -> obey Route indication
loose_route();
t_relay();
exit;
}
I checked on the termination windows machine and there is no CANCEL
received when I call through opensips (and disconnect while ringing).
But if I call directly to the windows machine the CANCEL is received
and call disconnected.
So the CANCEL arrives at opensips but is not forwarded to the termination.
What am I missing? How should I catch this message and forward it?
Thanks much,
Gabi
