Have you tryied to call from UA1 (behind your NAT) to other device out of your 
LAN? MediaProxy (if it well configured) should work in that case.

In case caller and called behind the same call, you explicitely **need** to 
allow direct RP in openser.cfg by matching $si with $dd (if pulbic source 
address and destination address is the same don't apply SDP fix).

But if you haven't configured it explicitely then maybe your conf is worng.
