All you need to know about deploying VoIP protocols in one
comprehensive and highly practical reference - Now updated with
coverage on SIP and the IMS infrastructure



This book provides a comprehensive and practical overview of the
technology behind Internet Telephony (IP), providing essential
information to Network Engineers, Designers, and Managers who need
to understand the protocols. Furthermore, the author explores the
issues involved in the migration of existing telephony
infrastructure to an IP - based real time communication service.
Assuming a working knowledge of IP and networking, it addresses the
technical aspects of real-time applications over IP. Drawing on his
extensive research and practical development experience in VoIP
from its earliest stages, the author provides an accessible
reference to all the relevant standards and cutting-edge techniques
in a single resource.

Key Features:

* Updated with a chapter on SIP and the IMS infrastructure

* Covers ALL the major VoIP protocols - SIP, H323 and
MGCP

* Includes a large section on practical deployment issues gleaned
from the authors' own experience

* Chapter on the rationale for IP telephony and description of
the technical and business drivers for transitioning to all IP
networks

This book will be a valuable guide for professional network
engineers, designers and managers, decision makers and project
managers overseeing VoIP implementations, market analysts, and
consultants. Advanced undergraduate and graduate students
undertaking data/voice/multimedia communications courses will also
find this book of interest.

Olivier Hersent founded NetCentrex, a leading provider of VoIP
infrastructure for service providers, then became CTO of Comverse
after the acquisition of NetCentrex. He now manages Actility,
provider of IMS based M2M and smartgrid infrastructure and
applications.
