TVOICE - Troubleshooting UC Systems v8.0

Course Description/Agenda

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

What You'll Learn

  • 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

Who Should Attend

  • Network administrators and network engineers
  • System engineers and field engineers
  • Anyone working toward CCNP Voice certification

Our investment in enhanced and exclusive labs means you get the experience you need using current software and hardware in North America.

UC labs are based on pods. Two students form a team and have control of one pod, referred to by the number N. The logical topology for a Global Knowledge UC pod is illustrated in the lab topology diagram for this course. A central Call Manager cluster deployed by your instructor is used to provide an IP telephony test environment that includes a simulated PSTN complete with 3-digit service codes, overlapping 7- and 10-digit patterns, and 11-digit and international patterns. Each pod also contains 2811 Integrated Services Routers running IOS 15.0(1)M2. The PSTN is accessible via a PRI, FXO ports, and SIP trunks. Global Knowledge lab topologies include Headquarters, Branch A, Branch B (with extensions that overlap with Branch A), and a Frankfurt branch. Headquarters, Branch A, and Frankfurt are illustrated in the lab topology diagram.

Our TVOICE lab environment consists of eight interconnected CUCM 8.0 pods. Two students are responsible for troubleshooting each pod. Each pod has three IP phones. Two of the phones are internal and the third is a test phone used to simulate outside callers. Cisco IP Communicator is used for phones at the HQ and Branch sites. Each pod has a CUCM Publisher.

The Global Knowledge lab environment has been customized for North American students to ensure that CCNP Voice Professionals learn the skills they need for the North American environment. Other training partners provide a basic topology oriented with a HQ in Europe and a branch in North America. Our expert instructors designed an enhanced topology that's better for understanding the issues with multisite deployment and globalization in North America and the nuances of implementing the NANP (e.g., 10-digit dialing, service codes beyond 911, issues with local and long distance calls to the same area code, overlapping 7- and 10-digit dialing, etc.).. Our labs focus on the needs of North American students:

  • A focus on the NANP
  • HQ in North America with multiple branches in North America with overlapping extensions
  • A branch in Frankfurt
  • Troubleshoot a real-world topology: A variable-length on-net dial plan supporting multiple sites with overlapping extensions, as described in Cisco's UC System Release 8.x SRND, using new v7 and v8 features, including local route groups and global transformations, that simplify the dial plan
  • Troubleshoot a globalized E.164 dial plan

The Global Knowledge lab environment also offers optional legacy labs that can be run by students if desired. A sophisticated telephony simulation is provided allowing students to troubleshoot PRI and FXO connections to the PSTN, T1-CAS DS0-Groups to a channel bank connected to two PBXs and FXS ports connected to analog phones. Each 2811 router is provisioned with a PVDM2-64 providing DSP resources and a serial card for WAN connectivity. The figure below illustrates the test environment for student pods 1 and 2 for legacy voice port connections.

All laptops have the following tools loaded:

  • VNC and terminal services
  • RTMT
  • Triple combo parser
  • translatorX
  • Wireshark

We offer more than 50 trouble tickets that instructors apply at their discretion during class, and additional trouble tickets are constantly being added.
