[asterisk-users] Disable CDR?

[Vincent]

Hello

I'm running Asterisk 1.4.21.2 on FreeBSD 6.3.

This part of extensions.conf...

;play a menu, and expect user to type any extension 1-4 or 9
exten => s,n,Wait(1)
exten => s,n,Background(main_menu)
exten => s,n,WaitExten(5)
exten => s,n,Hangup()

exten => _[1-49],1,AGI(convert_app.phpcli|${EXTEN})

...  triggers this message:

    -- Executing [s at main_menu:5] Wait("Zap/1-1", "1") in new stack
    -- Executing [s at main_menu:6] BackGround("Zap/1-1", "main_menu") in
new stack
    -- <Zap/1-1> Playing 'main_menu' (language 'fr')
  == CDR updated on Zap/1-1
    -- Executing [1 at main_menu:1] AGI("Zap/1-1",
"convert_app.phpcli|1") in new stack

I don't use CDR. Provided this will not have dire consequences, how
can I disable this?

Thank you.
