Re: [Kamailio-Users] problem with relaying invite

The FAILURE-ROUTE is automatically triggered if fr{_inv}_timer expires.

thanks for that, this is incase my first proxy is canceling the request route to second proxy, what about proxy does not reply at all . I can configure the timer using modparam("tm" , "fr_timer", 20) but how to route call to second if first proxy is timedout ?

thanks again

Of course, this is the manual approach for two gateways.  If you
have more than two gateways and need to cycle through a list, you
may want to consider the dispatcher module. s

             so then what is the posibility to send calls the first
        proxy if
           thats fail route to another one and so on ?


    The possibility is high.  :-)

    Here - try something like this:

    route {

       ...

       if(is_method("INVITE"))
          route(1);

       ...
    }


    # -- Relay INVITE -- #

    route[1] {
       t_on_failure("1");

       if(!t_relay("udp:proxy1:5060")) {
          xlog("L_INFO", "Final relay failure!\n");
          t_reply("503", "Service Unavailable");
          exit;
       }
    }

    # -- Backup INVITE route on failure of route(1) -- #

    failure_route[1] {
       if(t_was_cancelled()) {
          xlog("L_INFO", "Transaction cancelled.\n");
          exit;
       }

       append_branch();

       if(!t_relay("udp:proxy2:5060")) {
          xlog("L_INFO", "Relay to proxy2 failed - not so good!\n");
          t_reply("503", "Service Unavailable");
          exit;
       }
    }
