You can find the logic of the two functions: https://www.kamailio.org/docs/modules/devel/modules/permissions.html#sec-ad… https://www.kamailio.org/docs/modules/devel/modules/permissions.html#sec-tr… The permission module is quite old. Nowadays a lot of its functionality could be also implemented with simple configuration logic and e.g. the htable module for in-memory caching of the structures.
