[OpenSIPS-Users] Record congestion/failure rates per load balanced provider

[Sammy Govind]

Anyways yes you can call failure route while using the load_balancer too.
just use

t_on_failure("record-stats");
before calling the
if(!load_balancer("1","10"))

what it should do is send the call to an active destination and if that
active destination returns negative stats you can do something about those
in failure route.

Also her's some piece of code I collected from searching in 10 minutes.

# SELECT AN ACTIVE DESTINATION FROM LOAD_BALANCER ---RESULTSET GOES TO $du
if (!load_balance("1","mygws","0")) {
sl_send_reply("480","Temporarily Unavailable: service full");
exit;
         }
    ......
  .......
      # SEND THE CALL TO $du
if (!t_relay("0x09")) {
xlog("L_ERR", "Carrier termination failed with status code $rs: $rr using
outbound carrier: '$du' \n");
sl_reply_error();
};

Regards,
Sammy
