VoIP and Unified Communications (PDF)

Translates technical jargon into practical business
communications solutions

This book takes readers from traditional voice, fax, video, and
data services delivered via separate platforms to a single, unified
platform delivering all of these services seamlessly via the
Internet. With its clear, jargon-free explanations, the author
enables all readers to better understand and assess the growing
number of voice over Internet protocol (VoIP) and unified
communications (UC) products and services that are available for
businesses.

VoIP and Unified Communications is based on the author's careful
review and synthesis of more than 7,000 pages of published
standards as well as a broad range of datasheets, websites, white
papers, and webinars. It begins with an introduction to IP
technology and then covers such topics as:

* Packet transmission and switching

* VoIP signaling and call processing

* How VoIP and UC are defining the future

* Interconnections with global services

* Network management for VoIP and UC

This book features a complete chapter dedicated to cost analyses
and payback calculations, enabling readers to accurately determine
the short- and long-term financial impact of migrating to various
VoIP and UC products and services. There's also a chapter detailing
major IP systems hardware and software. Throughout the book,
diagrams illustrate how various VoIP and UC components and systems
work. In addition, the author highlights potential problems and
threats to UC services, steering readers away from common
pitfalls.

Concise and to the point, this text enables readers--from
novices to experienced engineers and technical managers--to
understand how VoIP and UC really work so that everyone can
confidently deal with network engineers, data center gurus, and top
management.
