Hi,

Use debug=4 when doing the ds_next_dst() - see the setdebug() function :
http://www.opensips.org/Documentation/Script-CoreFunctions-1-11#toc47

Also try an avp_print() after ds_select_dst() to see what data is kept into transaction.

Thanks for point out but still its not working, does my flags looks good? "F" or do i need something else? If i manually shutdown FS1 then it is going inside failure route and saying "No more gateways in route set" but i have FS2 active state and if i call again next call works.. do i need to set some like ( !ds_select_dst("1", "4", "F")) in failure_route ?

route[to_dispatcher] {
        # Dispatch to FS
        if ( !ds_select_dst("1", "4", "F")) {
                send_reply("500","Unable to dispatch call to Freeswitch");
                exit;
...
...


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

        ds_mark_dst("p");
        if(!ds_next_dst()) {
xlog("L_ERR", "R-DISPATCHER-ROLLOVER:$ci No more gateways in route set\n");
                t_reply("503", "Out of gateways");

        t_on_failure("dispatcher_rollover");
        t_relay();

    Hi,

    your logic in failure route is broken - do the "ds_mark_dst"
    before selecting a new destination via "ds_next_dst". Firs mark
    the used one as probing and then use the next one.

    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 :(
