[OpenSIPS-Users] ACK did not Receive on Proxy and get in loop

[SamyGo]

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.
