ACK must be sent to TOP most Record-route first but its going to sceond
Record-route first. Is it a correct behavior ?

I beleive you have to engage NAT corrections in reply route for 200OK.
I havent seen your SIP trace but if im Comtaact header the IP is of UAS and it
goes to the caller side ACK will get directly to that IP.
Just my guess. Need more info from you.

Sammy

ACK is not receiving on Proxy, It directly goes to UAS and get in loop at Proxy
before relayed to bob. Can you explain why ACK is going directly to UAS while
all other responses going to proxy?
