Hi. Thanks for the answer.

I changed fr_timer from "5000" to "500". Thanks for the tip. 

I use these tm module parameters:
fr_timer
fr_inv_timer

Unfortunately dispatcher module (ds_select_dst, ds_next_dst) didn't work for me as intended.

Only this code worked for me as expected.

request_route {
    if (is_method("INVITE|REGISTER")) {
    	rewritehost("10.0.0.65");
    	t_on_failure("FAILOVER");
    	t_relay_to_tcp("10.0.0.65","5060");
    	exit;
    }

failure_route[FAILOVER] {
    if (t_branch_timeout()) {
        rewritehost("10.0.0.75");
        t_relay_to_tcp("10.0.0.75","5060");
        exit;
    }
}

I still have some issues with this code tho.
I can't call back to sip subscriber, which uses kamailio ip as a registrar.
