Query: Good Intro for Those New to VoIP

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.
