Hi, I am trying to develop custom Kamailio module in C and I am wondering if Kamailio itself provide some kind of mechanism that allow me to call other modules functions. 

Most of the functions I need to call are defined as "static" and there are accessible only in kamailio.cfg file (eg. nathelper's 'fix_nated_sdp_f()'). 

Is there any chance that I can call these methods in my custom module? Or I need to use them only in kamailio.cfg and provide it with my module?

Thank's for help in advance.
