The ACK should be loose_routed. Verify which path in your config the ACK
packet uses:
if (loose_route()) {
xlog("L_INFO","$rm will be loose_route processed");
t_relay();
exit;
};
xlog("L_INFO","no loose_route processing for request
$rm");
which clients do you use?
we can help you more, if you post a comple ngrep dump

Hi folks,
I need an advice regarding failure routes.
I want the (Open)SER to route all incoming calls to a PSTN gateway. If
that route fails (e.g. because the gateway is down) it shall route the
calls to another gateway.
I managed to archieve that in the failure case the second gateway
receives the call. But the ACK request that the caller sends when
receiving the 200 OK is delivered to the primary target again, not to
the fallback gateway.
My configuration (excerpt):
route {
...
record_route();
if (loose_route()) {
t_relay();
exit;
};
t_on_failure("1");
t_relay_udp("192.168.0.37","5060");
}
failure_route[1] {
append_branch();
t_relay_to_udp("192.168.0.39", "5060");
}
Thanks in advance.
Regards,
Stefan
