You should check out the concept of 'SIP Trapezoid' http://www.tech-invite.com/Ti-sip-CF3261.html The ACK message is probably being sent from the called party back to the address on the contact HF - which is the NATed IP of the calling UA. Check the openser nathelper module to fix the contact HF or have to proxy add a record-route so subsequent requests will be sent to the proxy and not directly between the parties.
