Hi,
By "failing" you mean the "load_balance" function returns false in script ?
Could you post the output of:
opensipsctl fifo lb_list

Hi,
I am trying to use the load_balancer module for load balancing
requests between 2 OpenSIPS instances but my load_balance() function
is failing for reasons I couldn't figure out.
My load balancer table looks like this.
+----+----------+-------------------------+-----------+------------+-------------+

load_balance() is called from main route the following way-
if (load_balance("1","vm"))
{
xlog("L_NOTICE", "Loadbalancer: route:method ($rm) r-uri ($ru) :
Contact : $ct :callID $ci: destination: $du\n");
t_on_failure("3");
t_on_reply("1");
t_relay();
}
else
{
xlog("L_NOTICE", "Loadbalancer: route:method ($rm) r-uri ($ru) :
Contact : $ct :callID $ci: FAILED $retcode\n");
t_reply("500", "Service unavailable");
}
The function always fails and I couldn't figure out why.
What am I doing wrong?
Thanks,
Anshuman
