i use "ds_select_domain()" to route a call.
if the destination reply with an error i am using the next lines in a route that i called from the failure route:
after trying this line i do "kamctl fifo ds_list" and i see the host is still at "AX". and in the next call the dispatcher still tries the same destination.
