Hello, Could anyone help with suggestions on how to setup a Proxy ( R-Proxy) that only does a route lookup and pass the parameter back to origination Proxy/Gateway A to forward the call based on the new parameter.
On receipt of an invite from GW/Proxy A, R- Proxy will do a route lookup for the called number 447988870290, If it finds a route then it should append the network prefix to the new INVITE or rewrite the INVITE 23430442088870290 in the 302 Moved Temporarily message sent back to GW/Proxy A in the Contact field and there are two CC-Diversion header fields included; at GW/Proxy (IP address) who originated the call and already has a route or dial plan for the new prefix and also another one for same at GW/Proxy (IP address).
Is there any way to do this without creating a loop in the network ?
Previously this setup can be achieved with the originating network having 2 GW/Proxies i.e. GW/Proxy A and GW/Proxy B. In the 302 Temporarily moved message the Contact will show GW/Proxy B, while the 2 CC-Diversion header fields will add GW/Proxy B and GW Proxy A.
Regards, Abdul Hakeem
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.

Thanks for the response. Is Kamailio able to do a route lookup via HTTP get/post & pass the variables received to it's routing table before routing the call ?

Yes. Either use xhttp module (simple GET http request) or use a perl/python/lua script and do the http lookup in the script (for more complex http requests)
& pass the variables received to it's routing table before routing the call ?
there are no "routing tables", but you can implement any logic you need. E.g. the http response may contain a new Request URI which replaces the original one.
