I have it in my todo list to add the ability to do some filtering rules when to apply or not topology stripping -- actually even for topology hiding module, which reveals that was not a real high priority here as I didn't had really a need for it. In one occasion when I did need it, the platform was using edge proxies, so we added one dedicated for the traffic that needs the topoh, the rest being directed to the other edge proxies. You can do that even on same server, by running kamailio on a second interface or same net interface but different port. I was also considering simple ip matching rules, then thought of actually triggering an event_route where one can use modules such as permissions to decide to apply or not topology rules. If you want to contribute some code here, you can go for one that works easier for you. Later can be enhanced if someone needs more.
