Configuring Cisco Voice Over IP

The revolution of voice over data networking promises to lower costs, increase performance and transform companies' business communications strategies - and we all need to know about it. This book provides an indepth insightful presentation of both the big-picture strategic benefits and the down-dirty plumbing particulars. A truly valuable reference material.

The first couple of chapters provides a decent background on basic telephony and then moves on to discuss some of the emerging protocols and technologies. I would have liked even more configuration examples but all in all this proved to be useful.

While this isn't the end and be all book on VoIP it provides a good foundation for getting starting on the voice features in Cisco routers. For those of you that have to justify integrating VoIP into your network the first chapter covers some of the business reasons for doing so. The coverage on the different QOS methods I found helpful. Understanding the difference between WFQ and CBWFQ and why one should use the latter helped. The configuration examples were great, I just wish that there were more included.

This book provides excellent technical examples on how to configure Cisco VoIP products. The last chapter also includes information on the new AVVID IP phones. Information that I have been looking for. Also, valuable information that I haven't been able to find elsewhere such as how WFQ is not optimal for VoIP QOS and how CBWFQ and IP RTP Priority solve this problem. Good coverage of QOS concepts.

This is the book that I have been looking for. The first chapter of the book provides a good high level business justification for VoIP in the enterprise and then quickly launches into a background on the technology. Intricate detail on the particulars of H.323, SIP and MGCP. The following configuration chapters also clearly presented the concepts using examples and sample config files. Highly recommended for anyone considering a VoIP deployment. VoIP will be included on the CCIE as well.
