Voice over IP Fundamentals

5 Sessions -

12 Hours of Interactive Training

Voice over IP Fundamentals is designed to meet the requirements of the Cisco ICOMM v8.0 (640-461) exam. This course will introduce and teach individuals how to maintain and operate Cisco Unified Communications solutions that are based on Cisco Unified Communications Manager, Cisco Unified Communications Manager Express, Cisco Unity Connection, and Cisco Unified Presence. This is considered an associate-level course similar to LearnKey's Routing and Switching Fundamentals course. This course will introduce you to the architecture, components, functionalities, and features of Cisco Unified Communications solutions and will assist you in daily job tasks such as system monitoring, moves, adds, and changes performed on Cisco Unified Communications Manager, Manager Express, Unity Connection, and Unified Presence.
