Re: [Kamailio-Users] t_forward_nonack

I changed as you said, and here is the output:

[22782]: LOG: route 1 sip:613@fwd.pulver.com/<null> [22782]: LOG ---> T_ON_REPLY [22782]: ERROR:tm:t_forward_nonack: no branch for forwarding [22782]: ERROR:tm:w_t_relay: t_forward_nonack failed [22782]: LOG ---> T_RELAY

Hello,

replace line:

log(3, "LOG: route 1 \n");

with line:

xlog("LOG: route 1 $ru/$du\n");

and send again the output here. Note you need xlog module loaded.

Cheers, Daniel

Hello

X-Lite says: "500 Server error occurred".

Here is the debug: [19632]: LOG: route 1 [19632]: LOG ---> T_ON_REPLY [19632]: ERROR:tm:t_forward_nonack: no branch for forwarding [19632]: ERROR:tm:w_t_relay: t_forward_nonack failed [19632]: LOG ---> T_RELAY

and here is the code:

# ROUTE 1 route[1] { log(3, "LOG: route 1 \n");

    if (check_route_param("nat=yes")) {
            setbflag(6);
    }

            sl_reply_error();
    }
    exit;

}

    xdbg("new branch at $ru\n");

}

    xdbg("incoming reply\n");
    if ((isflagset(5) || isbflagset(6)) &&

# FAILURE ROUTE 1 failure_route[1] { log(3, "LOG: FAILURE ROUTE 1\n");

    if (is_method("INVITE")
                    && (isbflagset(6) || isflagset(5))) {
            unforce_rtp_proxy();
    }

    if (t_was_cancelled()) {
            exit;
    }

}

What could be missing? Thanks Joao Pereira

Hello,

do you call t_relay() or route(1) in your failure route?

Post your failure route here. Seems you try to forward a failed transaction without adding a new branch.

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 Regards Joao Pereira
