 Awesome note. 
How does one fire the RPC command. Whats the interface? Any docs on that?

 There are a lot of options here.

For source IPs and subnets, the `permissions` module probably works
best:

https://kamailio.org/docs/modules/5.1.x/modules/permissions.html

While it can function in a mode where it bangs on your database for
every request, it also supports a caching mode (db_mode 1):

https://kamailio.org/docs/modules/5.1.x/modules/permissions.html#permissions.p.db_mode

In caching mode, it loads the ACL from the database once on startup and
keeps it in memory. If you have made alterations to the database table
and want to kick Kamailio to reload it, there are management/RPC commands for that[2]:

https://kamailio.org/docs/modules/5.1.x/modules/permissions.html#permissions.r.trustedReload
https://kamailio.org/docs/modules/5.1.x/modules/permissions.html#permissions.r.addressReload

Note that in a lot of scenarios, use of the permissions module isn't
truly necessary because some other module provides a de facto ACL. For
example, if you are using the dispatcher[1] module to front-end a group
of servers for round-robin type load balancing, making routing decisions
based on whether the origin is within the dispatcher server pool seems
only natural[2]:

  if(ds_is_from_list("1")) { 
      # Allow from own application server farm.
}

For filtering out nonlocal URI domains, the `domain` module presents a
natural fit. It works much as `permissions` does in terms of in-memory
caching and that:

https://kamailio.org/docs/modules/5.1.x/modules/domain.html

And if you should find that these modules' data model doesn't
schematically meet your needs, you can always seed your own `htable`
values from a DB-backed hash table:

https://kamailio.org/docs/modules/5.1.x/modules/htable.html#htable.p.db_url

Or fetch these values from somewhere else (e.g. HTTP API) and inject
them into an htable upon startup:

https://kamailio.org/docs/modules/5.1.x/modules/htable.html#idp49461924

Lots of options...
