Hi Alex,
Have you tried the "use only the first GW" flag in the carrier
definition? See
https://opensips.org/html/docs/modules/3.0.x/drouting.html#idp25339408,
"Carriers" subsection:
flags : 0x1 - use weight for sorting the list and not definition order;
0x2 - use only the first gateway from the carrier (depending on the
sorting); 0x4 - disable the usage of this carrier

Hi Everyone,
Is it possible to failover to next carrier (instead next gateway)
while using drouting?
I got the below to work; however currently, use_next_gw gets the next
gateway in the list, so
if gwlist= #0,#3
and one of the carriers has multiple gateway IPs, the retry happens
many times to the same carrier:
route[droute] {
xlog("DRoute GATEWAY: source:$si - $fU -> $rU\n");
if (!do_routing(0,"F")) {
xlog("DRoute GATEWAY: Failed. source:$si -$fU -> $rU\n");
send_reply(500, "No Gateway to Route found");
exit;
}
route(relay);
exit;
}
route[relay] {
if (is_method("INVITE")) {
t_on_failure("missed_call");
}
if (!t_relay()) {
if (use_next_gw()) {
xlog("L_INFO","Next Gateway: From=$fu,
To=$tu,RU=$ru, CI=$ci IP=$si\n");
t_on_failure("missed_call");
route(relay);
exit;
}
else {
send_reply(503, "Service not available, no
more gws");
exit;
}
};
exit;
}
failure_route[missed_call] {
#if (use_next_gw(, , $var(carrier_attrs))) {
if (use_next_gw(, $avp(gw_id),$avp(carrier_id))) {
xlog("MissedCall--Next Gateway: From=$fu,
To=$tu,RU=$ru, CI=$ci IP=$si\n");
xlog("Carrier attributes of current gateway:
$avp(gw_id). carrier: $avp(carrier_id)\n");
t_on_failure("missed_call");
route(relay);
exit;
}
else {
send_reply(503, "Service not available, no
more gws");
exit;
}
Thank you.
