Would this work:  use append_branch() in the request_route, then in your 
failure route:



$var(temp_ru) = $ru;
t_next_contacts();
$du = $ru;
$ru = $var(temp_ru);

Yes, but I also need to specify a next hop, which append_branch does not 
support. There does not appear to be any mechanism for defining both a q-value 
and the d-uri. I can do one or the other but not both.

I think I will use KEMI and app_jsdt to sort them into the order I need.
