I'm using something like this:
 
######################################################################
# Route to main Gateway
######################################################################
route[1] {
 rewritehost("Main.Gateway.IP.Address");
 t_on_failure("1");
 t_relay();
}
 
######################################################################
# Route to secondary Mex. PSTN Gateway
######################################################################
failure_route[1] {
 log(1,"Main Gw failed or is busy. Trying secondary.\n");
 rewritehost("Second.Gateway.IP.Address");
 append_branch();
 t_relay();
}
 
Call will be routed to the second gateway if the first gateway is busy or down.
Does anybody know a method for load balancong?
 
Regards,
Jesus

Subject: [Serusers] Backup GW

Hi list,
 
My SER sends to a specific GW all the external calls, but I intend to have a secondary (backup) GW to terminate those calls would't be completed for some reason.
Does nbody knows how?
 
Thanks,
Vitor Brasileiro.
