the branch route scope would be:
- request uri
- destination uri (outbound proxy)
- branch flags
- changes to request (header and body manipulation)

t_on_reply() at it is works on transaction scope no matter where is 
used. So when it is called, it looks up the transaction based on 
call-id, cseq a.s.o. (in many cases the transaction pointer is cached, 
so just one lookup for a sip message) and the sets the value of the 
onreply_route name to be executed.

Cheers,
Daniel
