Description:

A guide to
successful deployment of the Cisco IP Telephony solution

Real-world case studies from the Cisco design
consulting engineers who developed the PDIOO process provide practical
advice on all stages of successful IPT deployment

Concise understanding of the PDIOO phases
enables architects and engineers to successfully deploy the Cisco IPT
solution

Division of the process into PDIOO phases
provides a logical and defined guide for network engineers and architects as
they proceed through each of the phases in deploying the Cisco IPT
solution

Includes detailed questionnaires for each
phase of deployment in the PDIOO cycle—a great aid in understanding customer
networks and requirements

Network infrastructure design, call processing
infrastructure design and applications, and voice-mail system design are
covered in depth
Cisco® IP
Telephony (IPT) solutions are being deployed at an accelerated rate, and
network architects and engineers need to understand the various phases
involved in successful deployment: planning, design, implementation,
operation, and optimization (PDIOO). On the road to that understanding, those
involved need to collect information for each phase of deployment, and then
follow through with the best architecture, deployment model, and
implementation based on the data collected.
 
Cisco IP Telephony: Planning, Design, Implementation, Operation, and
Optimization is a guide for network architects and engineers as they
deploy the Cisco IPT solution. With this book, you will master the PDIOO
phases of the IPT solution, beginning with the requirements necessary for
effective planning of a large-scale IPT network. From there, you’ll follow a
step-by-step approach to choose the right architecture and deployment model.
Real-world examples and explanations with technical details, design tips,
network illustrations, and sample configurations illustrate each step in the
process of planning, designing, implementing, operating, and optimizing a
chosen architecture based on information you have collected.
 
In-depth
instruction on each PDIOO phase provides specific details about the tasks
involved and best practices for successful implementation of the IPT solution.
This book also contains predesigned questionnaires and PDIOO assistance tools
that help you determine the requirements of each phase of the PDIOO
cycle.
 
Authors
Ramesh Kaza and Salman Asadullah have been involved with Cisco IPT solutions
from the beginning and have planned, designed, and implemented major IPT
networks using the guidelines found here. Cisco IP Telephony: Planning,
Design, Implementation, Operation, and Optimization provides the
step-by-step explanations, details, and best practices acquired by the authors
while working with the top Cisco IPT customers.
 
This book is
part of the Networking Technology Series from Cisco Press®, which offers
networking professionals valuable information for constructing efficient
networks, understanding new technologies, and building successful
careers.
