The approach is to start building it step by stem and use the mailing list to help sort out things when you are stuck. The default kamailio.cfg or the example config in dispatcher module are good starting points. Look also inside misc/examples/, there are plenty of configs there that can be used for learning or extracting parts to build a new config. Then you can come with specific questions, like: I want topology hiding, is that possible? Which is quick and easy to answer by community members: yes, look at topoh or topos modules.
