Course Description

​Our five-day instructor-led TVOICE course includes Cisco Unified Communications Manager Software v8.0 and prepares you for Cisco Exam 642-427 TVOICE.

This course equips you with the knowledge and skills required to troubleshoot Unified Communications (UC) systems and solutions in enterprise, mid-market, and commercial deployments. You'll learn problem triage, as well as troubleshooting methodology, resources, tools, and fixes at the integrated system/solution level. You will cover troubleshooting components, such as Cisco Unified Communications Manager (CUCM), Cisco Unity, videoconferencing, and network infrastructure.

We have refocused the standard TVOICE labs to give you hands-on experience troubleshooting a realistic North American dial plan to better simulate the environment you work in every day. You will troubleshoot a network with:


A different area code deployed simulating the North American Dial Plan (NADP)

Variable-length on-net dial plan supporting multiple sites with overlapping extensions

Headquarters in North America with multiple branches in North America and Europe

Local route groups and global transformations
