In short: There may be dragons there.

Anyways, I am not sure what you want to do, but you can usually skip the
problem by fixing the Request-URI and sprialing the call to yourself.

For instance, if call forwarding is what you're after, instead of
re-setting the target and just running processing again, you can just
stuff the URI you want to forward to in the Request-URI and call
t_relay() (don't forget the append_branch() if in a failure_route).

As a rule, keep failure and onreply routes simple. Actually, as a rule,
keep your config simple (Though simple does not necessarly mean short).
