[OpenSIPS-Users] ACK/BYE delivery

[Bogdan-Andrei Iancu]

Hi,

The Contact must reflect the IP of the other device in the dialog - if 
you are changing it, you are braking the in-dialog routing - you cannot 
simply change headers and still expect to work.

So, why do you want to change the in the 200 OK Contact the received IP 
with the IP of OpenSIPS ??
