Description

Troubleshooting Cisco Unified Communications Systems (TUC) v1.0 equips network professionals with the knowledge and skills required to troubleshoot Unified Communications systems & solutions in Enterprise, Mid-Market, and Commercial deployments. TUC teaches troubleshooting methodology, triage, resources, tools and fixes at the integrated system or solution level, and for components such as Cisco Unified Call Manager, Cisco Unity, videoconferencing, and infrastructure. This is a troubleshooting course and the learners should spend 60–70 percent of their time in the lab.

Objectives

Upon completing this course, the learner will be able to meet these overall objectives:

• Use a systematic methodology to troubleshoot Cisco Unified Communication systems by using knowledge of tools and reports that help isolate Cisco Unified Communication system problems
• When given a trouble call that has been categorized as a Cisco Unified CallManager-related issue, isolate the specific problem, propose a solution, and, where appropriate, implement the solution
• Diagnose a call setup issue and resolve the issues
• Troubleshoot the quality of both voice and video streams
• Given a trouble call that has been isolated to a Cisco Unified Communications system component application, the learner will be able to isolate the specific problem, propose a solution, and, where appropriate, implement the solution.
