[Freeswitch-users] lua error in session:transfer

[Adam Kelloway]

Just a hunch, but I would guess command line input is being treated as 
ints. Note that, in lua, 1 == 1 evaluates to true, while "1" == 1 
evaluates to false. I believe session:read returns a string.

http://www.lua.org/manual/5.1/manual.html#2.5.2

Also, the last two elseif statements could also potentially set 
target_number to nil, as you are only passing the script 4 arguments. 
Likewise for the empty else at the end.

Your transfer will work once this is fixed, assuming your have an 
extension called "target_number". Something tells me you actually want 
the extension number you are setting the variable to though, so you 
might want to remove the quotes around target_number when calling transfer.

Add some print statements in you if/elseif clauses to see which one 
resolve to true.

Hope those ideas help,

Adam
