[OpenSIPS-Users] Basic dynamic routing question

[Bogdan-Andrei Iancu]

Hi James,

I would say the script ids working, but you do not print the right 
stuff. After do_routing() the first GW is already set as ruri in the 
request; $avp(s:dr_ruri) is storing the next GWs to be used (if any). Try:


..
modparam("drouting", "attrs_avp", '$avp(s:dr_attrs)')
modparam("drouting", "ruri_avp", '$avp(s:dr_ruri)')
...
route {
...
        # set failure route for forward
        t_on_failure("1");
        # detect resources and do balancing
        xlog("-----Doing routing\n");

        if (!do_routing("1")) {
            sl_send_reply("503", "No destination available");
            exit;
        }
        xlog("----- gw attr is $avp(s:dr_attrs)\n");
        xlog("----- ruri is $ru\n");

        if (!t_relay()) {
          xlog("----- relay failed\n");
          sl_reply_error();
      }
}




Regards,
Bogdan
