Description

Poor planning and execution can cripple the enormous potential and business benefits of Cisco Unified Communications. The Cisco Unified Communications Architecture and Design course will help you 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.
