What are you proposing then Juha? not implementing RFC 5626 and continuing with custom solutions that don't work well? continuing with Contact rewritting? No please.
what comes to nat traversal, what are the problems with contact rewriting? so far it has worked quite well for me.
It's a hack! and it breaks SIP protocol as the UA should see a RURI matching its Contact in incoming requests, rather than a rewritten URI.
I cannot understand how the current hack should be preferred instead of implementing RFC 5626. "It seems to work with current hack" should not be a valid argument IMHO.
