Asterisk: The Swiss Army Knife of Telephony
Welcome to the wonderful world of Asterisk. You are about to discover the most powerful and popular open source PBX available.
Asterisk allows you to craft a telephony system to address your specific requirements. It does this by providing a library of basic telephony functions which you then use as script building-blocks. Calls into the system trigger these functions through digit patterns (referred to as extensions), giving you complete control of complex call routing concepts with relative ease. Common PBX functionality such as voicemail, call queuing, conferencing, music on hold and others are all included. But that’s just the beginning. Asterisk is one of the few PBXs in existence that connects legacy telephony technologies such as PRI or Analog trunks through the same switching logic as state of the art VoIP interfaces such as H.323 or SIP. This powerful yet simple core allows complex concepts in other systems to be deployed with ease in Asterisk. For example, building an IVR application or deploying CTI functionality can’t be done more inexpensively than with any other system. Why? Because with Asterisk, it’s all built right in!
Perhaps Asterisk’s most valuable asset is the open nature of the system. As with any open-source application, Asterisk can be further enhanced by the community of people who use it. This powerful concept ensures that Asterisk is prepared to mature in keeping with the demands of the industry. Go ahead and modify the source code to fit your needs, or, better still, contribute to an active and growing development community.
Because Asterisk is so powerful and flexible, in this book we can only begin to cover all the possible uses and configurations. We will therefore focus on the most commonly used features of the system and answer the most frequently asked questions. If you can work through the material we present here, you will be well on your way to becoming a competent Asterisk solutions developer.
We have also included appendices that will serve as excellent reference material, covering subjects such as application programming in C, configuration of various types of hardware, and many samples of configuration files. Also, there is a glossary included to help you find definitions for terms and acronyms used in this book.
