[Freeswitch-users] Record call in LUA

Hello, I can't find how to record a call from a LUA script. DEBUG shows no error but file is not created. Snippets of my LUA script and FS console log are provide below. api = freeswitch.API(); api:execute("record_session",call_recording_path..call_id..".mp3"); 2012-07-11 15:59:59.553048 [DEBUG] switch_cpp.cpp:1227 record_session /mydir/fc157da2-cb92-11e1-b8ad-65e540468340.mp3 The "mydir" directory is in 777 privilege access mode. Any thought anyone? Thank you. Bernard
