Hello,

version 5.0 doesn't have a lot of the functions from kamailio modules
exported to kemi (KSR module). Not even v5.1 will have all of them, but
I expect to be over 80% in v5.1.

There is a generic kemi function that can be used to execute any (most
of) functions from modules KSR.x.modf(...):

  -
http://kamailio.org/docs/tutorials/devel/kamailio-kemi-framework/kemimods/#ksrxmodf

If the kamctl rpc app_lua.api_list doesn't how a function you are
looking for, then it is not yet available via kemi (in KSR module).

Doing the old way with "register" modparam can be a solution only for
app_lua, if the respective module was added in the past to app_lua Lua
exports.

Cheers,
Daniel
