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?
