I have somewhere a function that does just that (using the above format). I used it a long time ago for load balancing (IIRC lb added received="..." to nated contacts when forwarding to the proxies behind it and removed "received" from r-uri, set the proper send socket based on dstip and the destination based on the received=uri when forwarding a message from a proxy to the outside world). I can create a new module for it (if it's not already in one of them).
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.
