Hi Jonathan
then if controller resides in a different entity , then will proxy take
care of routing the messages to the controller?
and how will the whole scenario be
like will it be something like this?
UAC --> Proxy ---> Controller ---> UAS
correct me if I am wrong.
thanks
Regards
Ranjit

No. Let us be clear here. Proxy is a logical function. A B2BUA does not
implement the proxy function. It is a pair of UA functions, "back to back".
