Hi Ricardo,
I think there is something wrong about how the sipquest device does routing based on RR and contact headers. There are 2 interesting things in your dumps: -In GW scenario, I don't see the Route inserted by SER (they have a special format with ftag and lr params). -In second scenario, there is no contact - both the ruri and Route contain the address of ser. Probably because of this, SER cannot route based on Route+contact and use usrloc which return 404.
Best regards, Marian Dumitru
