Cisco IIUC 1.0: Unified Communications Systems and Telephony Operations

This course is included in our On-demand training solution.


As corporate environments migrate towards VoIP technology, it is necessary to understand the basic tenets of traditional telephony and its interactions with traditional voice components. The Cisco Unified Communications (CUC) system provides the foundation for converged networks by offering a solution that encompasses voice, video, and data traffic within a single network infrastructure. This course introduces the CUC system and describes how this system uses shared services and open standards to virtualize voice, video, presence, and mobility services within the CUC systems framework. This course also explains how CUC equipment can manage the voice, video, and data traffic it carries, and how it can interface with all standards-based network protocols in each network class. The operation, components, and interfaces that are commonly found in a traditional telephony deployment are also covered. This course is one of a series from the IIUC 1.0 SkillSoft learning paths which cover the objectives for Cisco exam IIUC 640-460.

Target Audience

Network administrators, engineers, and managers; systems engineers; network designers; individuals seeking the Implementing Cisco IOS Unified Communications (IIUC) v1.0 certification


The skills and knowledge equivalent to those learned in Interconnecting Cisco Networking Devices Part 1 (ICND1); a working knowledge of how to configure and operate Cisco routers and switches
