Hello !

I'm using openser1.2.0 as a sip front-end to two asterisk servers. I need Load Balancing and Failover, so I'm using the dispatcher module.
I have a problem when I make a t_relay() since I have upgraded openser from 1.1.1 to 1.2.0 (my openser.cfg was working in 1.1.1 version)

Here are the modules and parameters I used :
debug=5
fork=yes
log_stderror=no
log_facility=LOG_LOCAL6
children=4
#check_via=no
dns=off
rev_dns=off

# ------------------ module loading ----------------------------------
loadmodule "/usr/local/lib/openser/modules/maxfwd.so"
loadmodule "/usr/local/lib/openser/modules/sl.so"
loadmodule "/usr/local/lib/openser/modules/dispatcher.so"
loadmodule "/usr/local/lib/openser/modules/tm.so"
loadmodule "/usr/local/lib/openser/modules/avpops.so"
loadmodule "/usr/local/lib/openser/modules/mi_fifo.so"
loadmodule "/usr/local/lib/openser/modules/textops.so"
loadmodule "/usr/local/lib/openser/modules/xlog.so"

#timer
modparam("tm", "fr_timer", 5)

#dispatcher
modparam("dispatcher", "list_file", "/usr/local/etc/openser/dispatcher.cfg")
modparam("dispatcher", "flags", 2)
modparam("dispatcher", "dst_avp", "$avp(i:100)")
modparam("dispatcher", "grp_avp", "$avp(i:101)")
modparam("dispatcher", "cnt_avp", "$avp(i:102)")
modparam("dispatcher", "force_dst", 1)

#fifo
modparam("mi_fifo","fifo_name", "/tmp/openser_fifo")



Here is the route for REGISTER method :
route[1] {
        ds_select_dst("1", "0");
        t_relay();
        t_on_failure("1");
}

and my failure route :
failure_route[1] {
        if(t_check_status("408"){
                ds_mark_dst();
                if(ds_next_dst) {
                    t_relay();
                }
                else {
                    t_reply("503", "service not available");
                }
        }
}

the fact is the t_relay() has no effect ... (users can't register on Asterisk)
for example when I make a forward() instead of a t_relay(), it's working (register works, with load balancing) ! But the t_on_failure("1") is never used, so I don't have failover ...

Thanks for your help !
