[Freeswitch-users] lua trouble

[Alex]

More lua trouble - real beginner stuff, I'm afraid.

Why does this not work:

         destnum = session:playAndGetDigits(3, 20, 3, 5000, "#", 
"/home/oev/fs-pabx/prompts/dmsb12_mcm3.wav", "", "\\d+\\*")
         l = strlen(destnum)

The objection is


2012-06-18 16:52:30.415261 [ERR] mod_lua.cpp:198 
/usr/local/freeswitch/scripts/mcm2.lua:13: attempt to call global 
'strlen' (a nil value)
stack traceback:
         /usr/local/freeswitch/scripts/mcm2.lua:13: in function 
'getDestNumber'
         /usr/local/freeswitch/scripts/mcm2.lua:49: in function 
'unattendedTransfer'
         /usr/local/freeswitch/scripts/mcm2.lua:24: in function 
'processMcmOption'
         /usr/local/freeswitch/scripts/mcm2.lua:153: in main chunk

I was just assuming that lua is lua and that anything in the lua wiki 
(eg. http://www.lua.org/manual/2.4/node32.html#exstring) would work.
