Cisco IP Communications Express: CallManager Express with Cisco Unity Express (ISBN 1-58705-180-X) is an all-in-one resource for configuring, managing, and troubleshooting the Cisco CallManager Express (CME) solution. It is almost 900 pages and is well organized into five parts: overview, feature operation and applications, administration and management, maintenance and troubleshooting, and appendices. If you are involved in configuring or maintaining the Cisco CallManger Express, this book will provide you with all the information you need to get your work done.
Cisco CME is an integrated solution offered by Cisco for meeting the IP telephony needs of small businesses or branch offices. The CME solution, which consists of the call processing feature and the voice mail feature, runs on the Cisco routers ranging from the 1700 series to the 3700 series and beyond. Whereas the CallManager suite offers centralized approach to building out an enterprise wide VoIP network, the CME is meant to serve the needs of smaller businesses or to integrate seamlessly into the larger, enterprise solution.
The book is well written and starts out with a high level architecture of the deployment scenarios for CME. The second part gets into the features and applications side of the solution. This part is where the crux of the book lies. It presents a detailed coverage of the commands used to configure the CallManager solution under various scenarios such as implementing different call features, integrating VoIP with PSTN, and deploying CME as part of a larger CallManager solution. This part presents a thorough coverage of Unity Express (UE), the voicemail module of the CME. The third part relates to the management of CME. Particularly useful in this part is a real-life configuration example as it illustrates and brings together a lot of the material covered in the earlier part of the book. Part four gets into the essential topic of troubleshooting the CME solution. It provides useful tips and solutions for common problems found in deploying the call processing and voice mail aspects of CME. This is definitely a very useful section of the book. The last part, the appendices, has reference materials and scripts used in the book to make daily tasks easier etc.
One of the strong points of the book is a multitude of sample configurations. The authors provide sample configurations throughout the book to help illustrate the concepts being presented. This sample configuration goes a long way if the reader has the task of actually configuring CME. The other strong point of the book is the depth of coverage given to each topic that is discussed. With the exception of a handful of topics (one in particular which I'll mention), the book never glosses over any topic; rather it covers it in detail, ensuring that most aspects of the topic are addressed. The exception to this was the coverage of the D/A module(s) used for attaching analog devices to CME, such as a fax machine. Given that analog fax machines still constitute a critical part of any business, I would expect this topic to be covered in detail. However, I found that no configuration examples were provided on how to configure this in the CME suite.
In summary, this book is a great all-in-one reference for configuring and managing CME. I would highly recommend it to any professional tasked with working on Cisco's CallManager Express.
