The review about this product
I picked up a copy of "Cisco Voice Gateways and Gatekeepers" to use as a study guide for the Implementing Cisco Voice Gateways and Gatekeepers (642-453 GWGK). This book was enormously helpful in successfully passing the exam. With that said, this is not an official Cisco Press exam study guide, in fact it cover much more, and was also beneficial to me in passing the CCIE Voice written.
As with most Cisco Press books, the opening chapter covers some basics, in this case the basics of Voice Gateways and Gatekeepers, as well as a high level review of gateway protocols and deployment scenarios.
The subsequent chapters jump right into the meat of the material. Each ensuing chapter covers each topic, such as H.323, SIP, MGCP, Dial Plans, and SRST with great depth and clarity. The book if full of very detailed and comprehensive sample configurations and debug outputs. Finally, the examples throughout the book are based off of the same case study network that is introduced in the opening chapter. As I consider sitting for the CCIE Voice Lab, I anticipate that I will revisit this book again and use the case study in my home lab.
I highly recommend this book to any looking to learning more about Cisco IOS Gateways and Gatekeepers, studying for the CCVP, and/or preparing for the CCIE Voice!
