Deploying Cisco Voice Over IP Solutions (Paperback)

This isn t a beginner s VoIP book; if that s what you need, consider Davidson s Voice over IP Fundamentals instead. But if you re already familiar with the basics, this book will bring you up-to-speed with the detailed guidance you need to design large-scale VoIP networks and implement the most widely requested VoIP services on them.

Davidson and his colleagues begin with key up-front design considerations: practical techniques for engineering and sizing traffic-sensitive voice networks; a complete methodology for eliminating the echoes that can plague VoIP networks; planning for QoS in diverse voice network environments; and Call Admission Control, for delaying calls when the network s too congested to handle them properly.

In Part II, the authors walk through designing service provider–based voice networks: first, static dial plans built around Cicsco H.323 gateways; and then, long-distance VoIP networks. Next, they turn to network services: managed multiservice networks and packet voice VPNs; store-and-forward and real-time relay fax services; unified messaging based on Cisco s uOne offerings; and prepaid services managed either through your internal network infrastructure or an Open Settlement Protocol (OSP) clearinghouse. If you re planning or implementing VoIP in Cisco environments, this is an indispensable resource. Bill Camarda
