Unified Communications Architecture and Design (UCAD)

Cisco Authorized 5-day Course on IP Telephony Technology


Course Description

Learn to avoid design disasters by exploring the breadth of technical issues in designing Unified Communications networks. By applying a consistent set of analytical tools, best practices, and design methodology to the complex set of requirements and problems faced by a systems engineer, the full potential for a stable, scalable, and feature-rich Unified Communications system can be realized.

 

Intended Audience

Design and sales engineers from customers, channel partners, and distributors

 

Prerequisites

CCNA Certification, QOS - Implementing Cisco Quality of Service and a working knowledge of existing legacy or IP Telephony
