Hello,

I found a workaround to my problem. On tm module I changed the failure_reply_mode parameter to 3. Now I don't have the internal error any-more. For now I can live with this workaround but in the future I was thinking about using the default value (1 - all branches are discarded by default).
Any idea why I get internal error if failure_reply_mode parameter differers from 3 (all previous branches are discarded if there is a new serial forking leg. This is the default behaviour coming from Kamailio 1.5.x.)

Cheers,

Miguel Baptista

Hello,

Here goes the the tcpdump capturing the traffic on my kamailio server. It is an incoming call to a internal user that sent a busy here.
Additionally I am also sending the capture of "the same" call without arming the failure route.
I cannot quite understand why is the phone sending two busy here SIP messages. Because the proxy already sent to it the ACK. Either way I don't think that is the reason for the internal error. Hmmm ... Curiously. sometimes the phone only sends one busy here .

TCP Dump - Call with failure route armed - internal error

Hello,

can you send a ngrep trace of such case, from the initial invite to the end of transaction? The debug messages you sent are only for the received reply, but it seems that 500 is sent already and then is just retransmitted, the SIP trace will help to clarify that.

Cheers,
Daniel

Hi all,

A couple of days ago I sent an identical email but because I wasn't a member of this list I don't know if you got it or not. Additionally, I would like to say that I have the same problem with kamailio 3.1.1. This is very weird problem ..

I am using kamailio 3.1.2 (like I say the same is happening with 3.1.1) and I have an issue with failure route. Every-time kamailio enters the failure route an internal error is triggered and kamailio sends a 500 SIP error message: SIP/2.0 500 I'm terribly sorry, server error occurred (1/TM).
Just for testing purpose I "downgraded" my failure route configuration to a very simple one. But even so I am always getting the same error and it doesn't matter if it is a busy, a cancel, a moved temporarily...
If I don't arm the failure route I don't get any error.

Any idea what might be wrong? Is this a bug?

This is the relevant part of my configuration :

route[RELAY] {
        if (is_method("INVITE")) {
                t_on_failure("FAILTWO");
        }
        if (!t_relay()) {
                sl_reply_error();
        }
        exit;
}

failure_route[FAILTWO] {
        xlog("L_INFO", "FAILUREFROMEXTERNAL: Entered\n");

        if (t_check_status("302")) {
                xlog("L_INFO", "FAILUREFROMEXTERNAL: 302 detected\n");
        } else {
                xlog("L_INFO", "FAILUREFROMEXTERNAL: other detected\n");
        }

xlog("L_INFO", "FAILUREFROMEXTERNAL: Exiting\n");
}

Here is the Debug output from a busy message got by kamailio and the internal error generated:
