TVOICE: Troubleshooting Cisco Unified Communications Systems v9.0
5 Days
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
  • A systematic methodology to troubleshoot Cisco UC systems
  • Knowledge of tools and reports that help isolate UC system problems
  • Use troubleshooting and monitoring tools
  • Troubleshoot common gateway and endpoint registration issues
  • Troubleshoot CUCM availability issues
  • Investigate database replication issues
  • Troubleshoot LDAP integration issues
  • Diagnose and resolve a call setup issue
  • Examine on-premises single-site calling issues
  • Troubleshoot on-net multisite calling issues
  • Investigate off-net calling issues
  • Troubleshoot SAF and CCD
  • Diagnose and resolve device mobility, extension mobility, and unified mobility issues
  • Investigate CUCM native presence issues
  • Troubleshooting MOH, MTP, conferences, and transcoder issues
  • Diagnose and resolve issues with RSVP agents
  • Troubleshoot the quality of both voice and video streams
  • Troubleshoot a globalized E.164 dial plan
  • Network administrators and network engineers
  • System engineers and field engineers
  • Anyone working toward CCNP Voice certification
The knowledge and skills that you must have before attending this course are as follows:
  • Working knowledge of converged voice and data networks.
  • Working knowledge of the MGCP, SIP, and H.323 and their implementation on Cisco IOS gateways.
