[Freeswitch-users] Problem Verifying an existing file with lua

[Sammy Govind]

Hey,
What I understand you are trying to do is get a variable name from FS and
check from LUA if the file exists ! file_name_ok is just a flag to return
true or false depending upon existence of caal_screen_filename..if this is
the case then

datei = session:getVariable("file_**name_ok");  --You are getting the
variable containing filename here.
shouldn't it be ?
datei = session:getVariable("call_screen_filename");

also,

if (file_exists(datei..extension.**.".wav")) then
> session:setVariable("file_**name_ok", "true");
> else
> session:setVariable("file_**name_ok", "true");
> end

returns true in any case file exists or not.

Please see if this is right !

Sammy
