[OpenSIPS-Users] dispatcher not doing fail over itself

following is my config,  I have two Freeswitch, if i stop one of freeswitch
and call it won't failover itself. but if again i call if send call to
other FS and if again i call it send to failed one but not auto failover..

But after my prob detect it is dead then it change status from Active to
Probing but that detection time is (10 to 30 second around), mean time it
should failover call to other freeswitch right?  we have 1000 call per
second and 10/30 second if big :(

        if ( !ds_select_dst("1", "4", "F")) {
                send_reply("500","Unable to dispatch call to Freeswitch");
                exit;
        } else {
        xlog("L_WARN", "dispatcher: Attempting to dispatch call to $du\n");
        }
        t_on_failure("dispatcher_rollover");
        route(relay);
}

failure_route[dispatcher_rollover] {
        xlog("Inside dispatcher failure route\n");
        if (t_was_cancelled()) {
                exit;
        }

        if(!ds_next_dst()) {
                xlog("L_ERR", "R-DISPATCHER-ROLLOVER:$ci No more gateways

                exit;
        }
        ds_mark_dst("p");
