Sorry for jumping in that late. It would be good if the description 
would be useful - thus, describing what the current (broken?) behavior 
is and how the new (fixed) behavior work.

I really wonder what is the problem with the current behavior.

Really? I often use proxies between Asterisk and the SIP clients and 
never had any issues - responses were always routed correctly

Please describe in more detail the problem with the old and new behavior.

thanks
Klaus

PS: Maybe you wanted to say "transparent" proxy instead of "stateless"? 
If a proxy is stateless, transaction statefull or dialog statefull does 
in no way influence the routing of the SIP messages.
