[OpenSIPS-Users] question about failure_route handling

[Woody Dickson]

Hi,
I am encountering problems with failure route.  Does anyone know what
is the cause of this error and how to resolve that?


Jan 20 15:18:58 localhost /usr/local/sbin/opensips[7964]:
ERROR:tm:t_forward_nonack: no branch for forwarding
Jan 20 15:18:58 localhost /usr/local/sbin/opensips[7964]:
ERROR:tm:w_t_relay: t_forward_nonack failed


Here is what i have in my failure route:

  if (t_was_cancelled()) {
                exit;
        };
        if (t_check_status("486")) {
                   prefix("b");
                  ds_next_domain();
                  route(1);
                        exit;
        };
        if (t_check_status("408") || t_check_status("480")) {
                prefix("u");
                ds_next_domain();
                route(1);
                exit;
        };


Thanks alot in advance for all your help.
