andrei,
there is a long thread on this and the needed functions have already
been written.
You will need also to save the local ip:port on which the packet is
received by the proxy. They will be needed when forwarding a packet with
and alias in r-uri, to make sure the same socket/ip:port will be used
for sending (or else it won't work with nats if you have several listen
addresses).
Isn't that already handled by record-routing? AFAIK RR header contains
the socket on which the request was received, and if incoming and
outgoing socket differ, then double-RR is used. Thus, isn't the
send-socket not already set after loose_route()?
This already works fine with fix_nated_contact(), and the new alias_...
functions do not change routing, the just preserve the original contact URI.
