However, I've noted that the ACK is different now from the previous trace. 
Please see tracefile below (adding
to tracker as well)

http://www.kerker.se/files/tandberg-polycom-ack-misrouted-sipxregistry-4.3.0-019022.xml

Frame 50-54 show the ACK. The outgoing ACK in frame 53 has a Request-URI 
addressing the NATed address with a Route 
header pointing towards the SipXproxy itself. In the next frame, the ACK frame 
54, this Route header is removed and the
only routing information left is the Request URI with the RFC 1918 address 
(sipX-privcontact). This address is not routable 
from the SipXproxy. 

If I put my Tandberg terminal on a public IP address and remove the NAT 
complexity, the call is completed correctly and
the ACK is routed correctly.
