Under programming for the autoattendants, when you get to the dial 0/time out action - you have the option to specify a transfer to extension for such calls to go to - so you need to modify that portion of the autoattendant menu. The default for the call service operator extension is the non-existant extension (I believe 768) under the system parameters options that preferably should be left as it is.
