Mathieu, Thanks for the reply. I'm very new with FreeSWITCH and not familiar with api calls. I tried: user_data = apiExecute("user_data", "1000@192.168.10.29 var callgroup"); But got a similar error: 2009-07-16 17:01:47.212904 [ERR] mod_lua.cpp:182 /usr/local/freeswitch/scripts/helloworld.lua:13: attempt to call global 'apiExecute' (a nil value) stack traceback: /usr/local/freeswitch/scripts/helloworld.lua:13: in main chunk I would appreciate an example or a link to the pertinent documentation.
