Hi,

In my failover setting using Dispatcher module, I mark the GW if fails to response. OPTIONS are being sent every 30 sec:

failure_route[DISPATCH_FAILOVER]{

   if (t_is_canceled()) exit;

   if (t_check_status("500") or (t_branch_timeout() and !t_branch_replied())) {

      ds_mark_dst("ip");

      if (ds_next_dst()) {

         t_set_fr(0,1000);

         t_on_failure("DISPATCH_FAILOVER");  

         route(RELAY);

         exit;

      }

   }

}

However, Kamailio still recognize it as active gw  ( A.A.A.A is down, no response from OPTIONS being sent)

$ sudo sercmd dispatcher.list

{

        SET_NO: 1

        SET: {

                SET_ID: 1

                DEST: {

                        URI: sip:A.A.A.A:5060

                        FLAGS: AP

                        PRIORITY: 0

                        ATTRS:

                }

                DEST: {

                        URI: sip:B.B.B.B:5060

                        FLAGS: AP

                        PRIORITY: 0

                        ATTRS:

                }

        }

}

Any help would be appreciated.
