Hi Daniel Sorry for the delayed response to this, the ACK is for a 200OK yes and the problem still persists in latest 4.4 and the 5.0.1 nightly build.
I have all DB entries/kam logs/pcap files. If you check the attached pcap, 192.168.70.70 and 192.168.252.70 are the same instance of Kamailio, it is being used to bridge the 2 networks. Frame 34 shows the 200OK with lots of Record-Route etc, and frame 35 shows topos in action. However the ACK that is relayed in Frame 38 seems to be missing all the Route information that was supplied in the 200OK, this causes the ACK to be relayed directly to the Contact, breaking the proxy chain.
