Asterisk: The Future of Telephony: The Future of Telephony

The first ninety percent of the task takes ninety percent of the time, and the last ten percent takes the other ninety percent .

The Ninety:Ten Rule

The toughest part of writing this book was not finding things to write about, but rather deciding what we would not be able to write about. Now that we've covered the basics, you are ready to be told the truth: we have not taught you anywhere near all that there is to know about Asterisk. Well, okay, perhaps five percent, but likely less.

Now please understand, this is not because we didn't want to give you our very best; it's merely because Asterisk is, well, limitless (or so we believe).

In this chapter, we want to give you a taste of some of the wonders Asterisk holds in store for you. Pretty nearly every section in this chapter could become a book in itself (and they will become books, if Asterisk succeeds in the way we think it is going to).
