Assist Telco and ISP engineers and technicians in their transition to IP
telephony

Assists traditional telco engineers and technicians in designing,
implementing, and supporting VoIP networks
Provides a step-by-step approach to designing a VoIP network
Outlines each VoIP technology components with detailed descriptions of
possible applications
Provides a thorough description of Voice over IP for those new to the
technology
Voice over IP (VoIP) is a fast-growing technology within telcos and ISPs.
VoIP is significantly reducing the cost of transmitting telephone calls and
enabling small companies to enter the +$50 billion marketplace. Many telcos and
ISPs are entering this market while VoIP is still in its infancy. As a result,
there is an urgent need for telco and ISP engineers to learn this new
technology. This book will assist telco engineers to transition to IP networking
with a focus on VoIP networks. This book introduces the fundamentals of IP
networking as it applies to transmitting voice calls using IP packets. Key
telco-based technologies such as SS7 are reviewed. A unique approach is that the
book outlines each component of VoIP technology while describing the application
of the technology. This is accomplished by describing key steps in designing an
operational VoIP network, thereby enabling the reader to understand how this
technology is applied.
