Deploying Cisco Voice over IP Solutions provides networking professionals the knowledge, advice, and insight necessary to design and deploy voice over IP (VoIP) networks that meet customers' needs for scalability, services, and security. Beginning with an introduction to the important preliminary design elements that need to be considered before implementing VoIP, Deploying Cisco Voice over IP Solutions also demonstrates the basic tasks involved in designing an effective service provider-based VoIP network. You'll conclude with design and implementation guidelines for some of the more popular and widely requested VoIP services, such as prepaid services, fax services, and virtual private networks (VPNs).
This book is a collaboration of Cisco Systems CCIE(r) engineers, technical marketing engineers, and systems engineers. You'll find design experience from people who have designed some of the world's largest VoIP networks.
Written by Cisco "RM" CCIEs "TM, " Technical Marketing Engineers, and Systems Engineers who have real-life experience with Cisco "RM" VoIP networks, this guide includes coverage of Virtual Private Networks (VPNs), admission control, security, fax and modem traffic, and unified messaging. Learn from real-world scenarios.
