Being the "R-Proxy" is quite easy with Kamailio.
# lookup route and set new RURI
...
prefix("23430");
# add any custom headers to response
append_to_reply(.....);
# send 302 (new RURI will automatically added as Contact header)
sl_send_reply("302","Moved");
exit;
Of course Kamailio has no influence how the Gateway will behave on
reception of the 302 response.
