这本书适合所有使用 Asterisk 的人阅读。
Asterisk 是一个开源的融合电话平台，主要设计用于在 Linux 上运行。Asterisk 融合了 100 多年的电话知识，是一套紧密集成的强大电信应用软件。Asterisk的强大之处在于其可定制性，以及无与伦比的标准合规性。没有任何其他专用交换机（PBX）能以如此多的创新方式进行部署。
语音邮件、托管会议、呼叫队列和代理、音乐保持和呼叫驻留等应用都是软件内置的标准功能。此外，Asterisk 还能与其他业务技术集成，这是封闭式专有 PBX 难以企及的。
对于新用户来说，Asterisk 的复杂性可能会让人望而生畏，因此文档对其发展非常重要。 文档降低了入门门槛，帮助人们思考各种可能性。
Asterisk:The Definitive Guide》由 O'Reilly Media 慷慨赞助，是《Asterisk :The Definitive Guide》的第五版： 电话的未来》的第五版。
本书是为 Asterisk 社区成员编写的，也是由他们编写的。
观众
本书旨在温和地对待那些Asterisk新手，但我们假定你熟悉基本的Linux管理、Network+和其他IT学科。如果不熟悉，我们鼓励你探索O'Reilly出版的有关这些主题的大量精彩书籍。我们还假定您对电信（包括传统交换电话和新的 IP 语音世界）相当陌生。
不过，这本书对更有经验的 Asterisk 管理员也很有用。我们自己也把这本书作为很久没用的功能的参考书。
软件
本书的重点是记录 Asterisk第 16 版；不过，书中的许多约定和大部分信息与版本无关。Linux 是我们运行和测试 Asterisk 的操作系统，我们记录了 CentOS（Red Hat Enterprise Linux，简称 RHEL）的安装说明。
