I am trying that but it seems like that when an IP is filtered it
doesn't even go to failure route.
This is what i have in my config:
In route[4] I have:
t_on_reply("4"); # grab replies so we can log reply
code/status
t_on_failure("4"); # if gateway unavail go to 4
if (!next_gw()) {
sl_send_reply("503", "Service not available - No gateways");
return;
};
if (!t_relay()) {
sl_reply_error();
};
xlog("L_INFO","$ci: leave route[4]: - M=$rm RURI=$ru F=$fu T=$tu
IP=$si\n");
} # end of route[4]
failure_route[4] {
xlog("L_INFO","$ci: failure_route[4] - M=$rm RURI=$ru F=$fu T=
$tu IP=$si\n");
if (t_check_status("(5..)|(6..)|(403)|(408)|(473)|(480)")) { #
gateway failure/refusal
xlog("L_INFO","$ci: failure_route[4] gateway failure/refusal
\n");
if (!next_gw()) {
xlog("L_CRIT","$ci: No more gateways for <$tu>\n");
t_reply("503", "Service not available - No more gateways");
return;
} else {
xlog("L_INFO","$ci: failure_route[4] next gw r-uri <$ru>
\n");
t_on_reply("4");
t_on_failure("4");
t_relay(); # send it off to try next gw.
return;
}
}
xlog("L_INFO","$ci: failure_route[4]: relaying normal error\n");
t_relay();
}
First time around calls do make it to failure route, however, when an
IP is blacklisted, it never makes it to to the failure route.

Hi,
Can someone please comment on how to capture and act on this 473
filtered from within OpenSER config, i.e., ability to failover to
next gateway returned by the LCR. I have tried to capture that with
no success.
Hello,
have tried to call next_gw() in the failure route?
