Hello List.
I have the next situation. I'm trying to build a "LCR" but using the
information from a Radius Server, so 'im using the avp_radius module to
obtain the "next_gw" data from my DB.
So far so good, I have been able to retry a failed call with the next
gateway in the list. In my tests I'm using a list of 3 gateways and I'm
seeing the next behavior : I have all the gateways off-line, so the
call is redirected to the first, second and and finally to the third
gateway, when there is no moer gateways to try I have this statement in
my config file :
if( there is gateways to try on the list... ) {
route(1);
} else {
sl_send_reply("503", "No more DB routes");
exit;
}
I send the "503 - No more DB routes" but the Kamailio also send a "408
Request Timeout".
What could this be happening? I even tried with just one gateway on the
list, with the same results. I was expecting just the "503" message,
and not the "408".
Hope that someone could help me.
I'm attaching my kamailio-snnipet.cfg file and a full debug with the
behavior.
Thanks!
