[Kamailio-Users] t_forward_nonack

[Joao Gomes Pereira]

Hello
I'm getting this error when I try to do URI calls:

LOG ---> T_ON_REPLY 
ERROR:tm:t_forward_nonack: no branch for forwarding
ERROR:tm:w_t_relay: t_forward_nonack failed
CRITICAL:tm:t_should_relay_response: pick_branch failed (lowest==-1) for 
code 408

And X-Lite says: "Server error occurred"

My config is based in the sample configuration file that comes with 
Kamailio.
Here is my route[1], where the call should be routed:


route[1] {

        if (check_route_param("nat=yes")) {
                setbflag(6);
        }
        if (isflagset(5) || isbflagset(6)) {
                route(5);
        }


        /* example how to enable some additional event routes */
        if (is_method("INVITE")) {
                #t_on_branch("1");
                log(3, "LOG ---> T_ON_REPLY \n");
                t_on_reply("1");
                t_on_failure("1");
        }

        if (!t_relay()) {
                sl_reply_error();
        }
        exit;
}


My "branch_route", "on_reply_route" and "failure_route" are just like in 
kamailio.cfg.sample.

What could be causing this errors?
Thanks
