Fax, Modem, and Text for IP Telephony ReviewThis is a great reference book to understand the latest fax, modem and text for IP telephony technologies. It is certainly not for beginners but more suitable for anyone who has worked with, installed and supported these systems. The prior knowledge of call control protocols, voice gateways, Quality of Services (QoS) and familiarity of Cisco unified voice products and networking is very helpful to understand this book.The book is divided into four parts starting from fundamental theories, solutions and designs, configuration and troubleshooting. It starts with the basic knowledge on how modem, fax and text telephony works. They come with good illustrations and are very easy to understand. Due to space limitation and various standards, the books only addresses the most common and important protocols for each technology.
The next part describes various switchover methods and transport options to handle fax, modem and text communication. There are so many technical jargons and complex concepts here that readers who are not familiar with these before, can get lost very fast. The book does a good job describing and comparing each method. The best part of this section is on the design guide chapter which shows reader what design considerations they have to review before implementing fax, modem and text communication for different hardware and network.
The configuration part shows various commands and configurations for fax, modem and text for many varieties of Cisco products. I understand that the authors include the configuration parts to complete the reference part of the book. However, since there can be many different commands for different products in different IOS software version, it is best to look up Cisco documentation in the Cisco web site directly rather than using this for configuration basis.
The last part describes the troubleshooting techniques and procedures used by Cisco TAC engineers to resolve fax, modem and text problems. This is the best part of the book to get the insight on how "divide and conquer" troubleshooting is done to find the cause of the problem. It is not easy considering the amount of devices and protocols involved to integrate the fax, modem and text system.
I am usually skeptical on any books that try to claim as definitive resources since they usually come short. However, this book is different. The authors successfully manage to incorporate all these technologies and cover them in details. Some readers might think that the delivery is quite dry but it is expected from a resource book. I rate this book 5 out of 5 starts and recommend this book for people who work with the IP Telephony.
Fax, Modem, and Text for IP Telephony OverviewIP Telephony has revolutionized many aspects of telecommunications and it continues to be deployed at a rapid pace. The benefits of transporting voice over an IP infrastructure include increased flexibility, better scalability, and a significant cost savings over traditional telephony networks. However, during the deployment of these VoIP solutions, other types of traditional telephony communications that can also realize these same benefits are often overlooked or ignored. Fax, Modem, and Text for IP Telephony is a comprehensive resource that confronts the need for information on transporting alternative, non-voice communications over the IP protocol. Beginning with the basic theory and operation of fax, modem, and text telephony, this book then educates you on all of the current transport options that are available. An extensive design guide then provides the pertinent advice and best practices for making the correct planning decisions and choosing the best transport option for your network.Fax, Modem, and Text for IP Telephony also includes meticulous configuration and troubleshooting guides. The configuration guides in this book include a number of sample configurations and tips to manage any fax, modem, or text deployment. The troubleshooting guides present the essential methodologies, debugs, and analysis tools for quickly resolving both the common and complex issues that may be encountered. This book is the perfect companion to other VoIP resources, and it is the only book that empowers you to successfully handle any fax, modem, or text implementation.David Hanes, CCIE® No. 3491, is currently a senior engineer specializing in training, network design assistance, and troubleshooting of fax technologies for the Customer Assurance Engineering (CAE) group at Cisco®.
