Title: Excellent intro to VoIP
Review: This book does a very good job of giving an introduction to the VoIP world. As a professional in the telecom domain, I found this book very useful. Application of VoIP to telco domain as in the case of softswitch architecture for backhaul and the QoS issues that carriers have to deal with is also well covered at a good amount of detail. The book also provides detailed discussion on the protocols. However, I skipped passed these sections and unable to comment if such material was covered well.Overall - a very good book. Highly recommend it.
