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(...):

Hello Daniel,

hello List,

after reading the fresh released kemi documentation (Thanks for that!) on github i start to configure an kemi lua configuration. It seems to be that there is not an dispatcher export to kemi in my installation. Or i missconfigured something? How to use dispatcher with kemi?

1.) First try to solve this - use param "register" "modulename" to app_lua - doesnt work

2.) grep around in the auto kemi in/export messages in debug startup - nothing to see.

3.) grep around in the kamcmd api.list command for lua - no dispatcher

here the intressting parts of the configs and lua-script:

kamailio.cfg

...

loadmodule "dispatcher.so"

loadmodule "permissions.so"

loadmodule "avpops.so"

#!ifdef WITH_CFGLUA

loadmodule "app_lua.so"

modparam("app_lua", "reload", 1)

modparam("app_lua", "register", "dispatcher")

#!endif

#!ifdef WITH_CFGLUA

modparam("app_lua", "load", "/etc/kamailio/lua/kamailio-kemi-lua.lua")

cfgengine "lua"

#!else

import_file "request-route.cfg"

#!endif

...

kamailio-kemi-lua.lua

function ksr_request_route()

...

    -- dispatch destinations

    if KSR.permissions.allow_source_address(FLT_EDGE) then

        KSR.info("new $fU -> $rU in permissions");

        direction = "inbound";

        routing_target = FLT_FSNODE;

        ksr_route_dispatch(direction, routing_target);

        KSR.x.exit();

    end

    KSR.info("NOT-OKAY - $rU dropped");

    -- End of Route()

    KSR.sl.sl_send_reply(407, "Proxy Authentication Required. See IP GUI");

    return 1;

...

end

--- dispatcher route

function ksr_route_dispatch(direction, routing_target)

    KSR.xlog.xinfo("new $fU -> $rU in routing_target ksr_route_dispatch");

    KSR.info(routing_target);

    if (routing_target == nil) then

        KSR.xlog.xinfo("routing_target nil");

        KSR.sl.sl_send_reply(604, "Does Not Exist Anywhere");

        KSR.x.exit();

    end

    if KSR.dispatcher.ds_select_dst(routing_target, 4) then

        send_reply(404, "No destination");

        KSR.x.exit();

    end

    ksr_route_myheader();

    ksr_route_relay();

    KSR.x.exit();

end
