Can Anyone tell me is it possible to route calls based on from_uri with the LCR Module??

I see the from_uri field but I have tried using  %@192.168.1.1  & 192.168.1.1 
I replaced 192 address with an actual IP of another SER box that is Trusted. No matter

what I put in there it still routes to the % only group. Even when I dial the prefix related

to that entry.
