Learn real-world voice
over IP deployment solutions and
strategies from the Cisco experts!
Deploying Cisco Voice over IP Solutions provides
networking professionals the knowledge, advice, and insight
necessary to design and deploy VoIP networks that meet
customers' needs for scalability, service, and security.
Compiled by Jonathan Davidson, co-author of the Cisco Press
title Voice over IP Fundamentals, Deploying Cisco
Voice over IP Solutions picks up where his first book
left off by demonstrating how to design these
next-generation networks. If you have already read Voice
over IP Fundamentals, look to this book as your next
step in building VoIP networks.
- Written by Cisco CCIEs, Technical Marketing Engineers,
and Systems Engineers who have real-life experience with
Cisco VoIP networks
- Includes coverage of Virtual Private Networks (VPNs),
admission control, security, fax and modem traffic, and
unified messaging
