AFAIK every response with response value >= 300 will trigger the failure 
route.

no glue. check the source code.

T hink I do not get your setup right. What do you want to achieve? If 
you use t_reply, you should not setup a failure route.

The current route block will be executed until the end of the route 
block or exit/return. (As without using t_on_failure)

Then, typically some seconds later, when the failure happens, the 
transaction enters the failure route.
