[OpenSIPS-Users] Setting do_routing

[Nick Cameo]

Hello Bogdan,

I had a chance to include the patch in our environment. I forgot to
mention that we
have an avp with the gwlist loaded, and route_to_gw does not accept
avps? Is this
possible to have.

Just for testing, I continued by hard coding an arbitrary gwlist.
Snips of the config:

....
route[1] {
        if (is_method("INVITE")) {
                $var(doOrder) = perl_exec("doOrder");
                    if($var(doOrder)==1) route_to_gw("7,1,4");
.....
}


failure_route[1] {
                if (use_next_gw()) {
                      xlog("L_INFO","Next Gateway: From=$fu, To=$tu,
RU=$ru, CI=$ci IP=$si\n");
                      t_on_failure("1");
                      route(1);
                      exit;
                }
                else {
                        t_reply("503", "Service not available, no more gws");
                        exit;
                }



What I found with the above config is that OpenSIPS did not iterate through the
gwlist on failures. It simply re invited the same gateway and failed
again. Bellow
are some errors that I observed when testing.

I'm probably missing something? Also, regarding accepting avp as a parameter of
route_to_gw, it's needed quite urgently.

I really appreciate all your help.

Kind Regards,

Nick.
