[SR-Users] Proxy setup in a non-recursive mode

[Abdul Hakeem]

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
