Количество страниц: 408-It may be a while before Internet telephony with VoIP (Voice over Internet Protocol) reaches critical mass, but there's already tremendous movement in that direction. A lot of organizations are not only attracted to VoIP's promise of cost savings, but its ability to move data, images, and voice traffic over the same connection. Think of it: a single Internet phone call can take information sharing to a whole new level.
That's why many IT administrators and developers are actively looking to set up VoIP-based private telephone switching systems within the enterprise. The efficiency that network users can reach with it is almost mind-boggling. And cheap, if the system is built with open source software like Asterisk. There are commercial VoIP options out there, but many are expensive systems running old, complicated code on obsolete hardware. Asterisk runs on Linux and can interoperate with almost all standards-based telephony equipment. And you can program it to your liking.
Asterisk's flexibility comes at a price, however: it's not a simple system to learn, and the documentation is lacking. "Asterisk: The Future of Telephony" solves that problem by offering a complete roadmap for installing, configuring, and integrating Asterisk with existing phone systems. Our guide walks you through a basic dial plan step by step, and gives you enough working knowledge to set up a simple but complete system.
What you end up with is largely up to you. Asterisk embraces the concept of standards-compliance, but also gives you freedom to choose how to implement your system. "Asterisk: The Future of Telephony" outlines all the options, and shows you how to set up voicemail services, call conferencing, interactive voice response, call waiting, caller ID, and more. You'll also learn how Asterisk merges voice and data traffic seamlessly across disparate networks. And you won't need additional hardware. For interconnection with digital and analog telephone equipment, Asterisk supports a number of hardware devices.
Ready for the future of telephony? We'll help you hook it up.-

Количество страниц: 608-This bestselling book is now the standard guide to building phone systems with Asterisk, the open source IP PBX that has traditional telephony providers running scared! Revised for the 1.4 release of the software, the new edition of "Asterisk: The Future of Telephony" reveals how you can save money on equipment and support, and finally be in control of your telephone system.
If you've worked with telephony in the past, you're familiar with the problem: expensive and inflexible systems that are tuned to the vendor's needs, not yours. Asterisk isn't just a candle in the darkness, it's a whole fireworks show. Because Asterisk is so powerful, configuring it can seem tricky and difficult. This book steps you through the process of installing, configuring, and integrating Asterisk with your existing phone system.
You'll learn how to write dialplans, set up applications including speech synthesis and voice recognition, how to script Asterisk, and much more - everything you need to design a simple but complete system with little or no Asterisk experience, and no more than rudimentary telecommunications knowledge. The book includes:
- A new chapter on managing/administering your Asterisk system
- A new chapter on using Asterisk with databases
- Coverage of features in Asterisk 1.4
- A new appendix on dialplan functions
- A simplified installation chapter
- New simplified SIP configuration, including examples for several popular SIP clients (soft phones and IP telephones)
- Revised chapters and appendicies reviewed and updated for the latest in features, applications, trends and best-practices
Asterisk is revolutionizing the telecom industry, due in large part to the way it gets along with other network applications. While other PBXs are fighting their inevitable absorption into the network, Asterisk embraces it. If you need to take control of your telephony systems, move to Asterisk and see what the future of telecommunications looks like.-
