The module is not for hiding/changing the ip address of kamailio server. 
That is known (and must stay there for routing) by both sides of the call.

The module is to hide the IP addresses of the other nodes in the path of 
the call, so, when A is calling B, none of them know the real ip of the 
other. But obviously A and B must know the ip of kamailio.

The way it works with topoh: it replaces the ips of A and B with a 
'fake' IP -- the fake IP just have to conform with the IP address format 
and not to be server IP. It can be a non-public-routable IP, because it 
is used just as a place holder in the SIP headers, to stay conformant 
with SIP grammar. Therefore you can use there an IP such as 127.0.0.44 
(which is not allocated anywhere and not routable).
