But anyway... why should be Via sent-by be used to send the response?
RFC 3261 says clearly that if a proxy receives a request in which Via sent-by 
differs from real source address, then "received=PUBLIC_IP" must be added to 
top Via.
If the request is forwarded stateless, when the reply arrives it must be sent 
to the "received" address (if it exists).

AFAIK "reply_to_via=1" is needed for implementing a stateless proxy with 
OpenSIPS, isn't it? But in that case, the responses must be sent 
to "received" address when present.

Am I wrong?
