In failure_route[2] try rewriting the host /port to that of the second gateway then issue the t_relay. You may want to check the status of the t_relay if that is important.

Hello,

I am trying to setup the ser.cfg to perform failure route. I have two PSTN gateways and would like to forward the INVITE to gateway 2 if gateway 1 failed.

My ser.cfg is as follows:

route{

    xlog("L_NOTICE", ">>>>>>>>>>>>>> Proccessing method %rm from 

%fu <<<<<<<<<<<<<\n");

    if ((method=="REGISTER") || (method=="NOTIFY") || 

(method=="OPTIONS"))

    {

            xlog ("L_NOTICE", "REGISTER");

            sl_send_reply("200", "ok");

            break;

    }



    rewriteuri("sip:1000@71.137.189.10:21100");

    t_on_failure("1");

    t_relay();

}

failure_route[1] {

    append_branch("sip:1000@71.137.189.10:22100");

    t_on_failure("2");

    t_relay();

}

failure_route[2] {

    append_branch("sip:1000@71.137.189.10:23100");

    t_relay();

}

Gateway 71.137.189.10:21100 returns a 404 NOT FOUND to SER, and I see SER proceed to send the INVITE to 71.137.189.10:22100. The 2^nd gateway returns 183 (proceed). I was expecting SER to forward the SDP from 71.137.189.10:22100, however, the SDP actually was the SDP from gateway 1. How can I get SER to forward the reply from GWY2 and update the SDP information?

Thanks
