[Serusers] current uri

[Matt Hess]

How is the current uri handled when passed between route blocks?
In my various failed attempts to do something like hunt (or ring) 
groups, call forwarding etc.. I have really hit a big stumbling block..

Is there something that would prevent the current uri from being 
modified by an exec_dset? Does failure_route handle things different 
from normal routes? Has anyone ever successfully setup a system that can 
handle multiple hunt groups or call forwarding?
