$du is the address of next hop and it is set due to the Path headers in 
this case. In the case there is no intermediary proxy, it will be the 
address of the NAT router.

In case you have many contacts for same users, then you have to look 
also at the other branches, which are accessible via $branch(...).

This might not work for multiple contacts. I even wonder if there is a 
RFC saying what to do in the case there are many contacts with different 
Path headers. Path headers have to be turned into Route headers after 
lookup(), but for redirects?!? Shall Path should be added in reply? Any 
IETF guru around that can shed some light?

Cheers,
Daniel
