Re: [Kamailio-Users] problem with relaying invite

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.

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;
}

}
