[OpenSIPS-Users] Gateway failover special setup (t_check_status question)

[Max Mühlbronner]

Hi,


my scenario is a special setup where we are checking for the reply code 
(t_check_status) and only do a failover to the next gateway when there 
is a 444 reply or gateway type is not "1".

...

         if (use_next_gw()) {
                 if( t_check_status("444") || !goes_to_gw("1") ) {
                         t_on_failure("2");
                         t_relay();
                         exit;
                 }


The problem is, there are multiple gateways in a carrier/gatewaylist 
(gateway type 1) which are not responding (t1 timer hits and invite is 
re-transmitted) and there is no failover after the first gateway 
anymore. Is there anything i am missing, is it even possible to do 
failover only for the 444 reply while at the same time still doing a 
failover in case of Timeout-based failover ? (t1/t2 timers)


I didn't try yet, but is something like !t_check_status("\d") feasible? 
E.g. doing a failover if there is no t_check_status (checking regular 
expression for !digits?) but i guess it does not work that way?


         if (use_next_gw()) {
                 if( t_check_status("444") || !goes_to_gw("1") ) {
                         t_on_failure("2");
                         t_relay();
                         exit;
                 }

                 if(!t_check_status("\d")) {

                         t_on_failure("2");
                         t_relay();
                         exit;

                  }

     ...
