CVOICE – Implementing Cisco Unified Communications VoIP & QoS v8.0

Training Duration:

5 days

Audience:

Employees of federal, state and local governments; and businesses working with the government.

Prerequisites

  • Working knowledge of networking fundamentals, including LANs, WANs, and IP switching and routing
  • Ability to configure and operate Cisco routers and switches and to enable VLANs and DHCP
  • Knowledge of traditional PSTN operations and technologies

Course Description:

Cisco Course v8.0 | Prepares you for Cisco Exam 642-437.
In this course, you’ll gain an understanding of converged voice and data networks and the challenges faced by various network technologies. Addressing design, planning, and deployment practices, you will gain comprehensive hands-on experience configuring and deploying VoIP networks.

In addition to the knowledge and skills required to integrate gateways into an enterprise VoIP network, you’ll learn how to build and test a sophisticated IP telephony network that you can use as a template for a real deployment.

The course includes a comprehensive full day on Quality of Service (QoS), in which you’ll learn to configure QoS to support real-time traffic.

The extended hours of this course (8:30am – 6:00pm each day) provide you with the most complete training experience possible, ensuring you have time to absorb and fully grasp the in-depth content that will be covered.

What You’ll Learn

  • VoIP, components of a VoIP network, VoIP protocols, special requirements for VoIP calls, and Codecs
  • Configure gateway interconnections to support VoIP and PSTN calls
  • Basic signaling protocols used on voice gateways
  • Configure a gateway to support calls using different call control and signaling protocols
  • Define a dial plan, describing the purpose of each dial plan component, and implement a dial plan on a voice gateway
  • Implement a Cisco Unified Border Element (CUBE) gateway to connect to an Internet Telephony Service Provider
  • Exclusive – Investigate the use of various traditional telephony connections, such as FXS, FXO, E&M, T1 (CAS and PRI), and E1 (CAS and PRI)
  • Configure and troubleshoot Cisco’s new ISR routers (2811s) and explore their DSP configuration (PVDM2-32 cards)
  • Configure H.323 gateways and gatekeepers and review their functions and operation
  • Configure Session Initiation Protocol (SIP) and Media Gateway Control Protocol (MGCP)
  • Experience G.711, G.723, and G.729 voice coding schemes
  • Configure Call Admission Control three different ways
  • Configure proper Caller ID
  • Experience real-world connections to PBXs, Key Telephone Systems, and the PSTN
  • Configure your router/gateway equipment to connect to our public dial plan network using different call control protocols and procedures

Who Needs to Attend

  • Students completing the CCNP Voice certification track
  • Network engineers, architects, and support staff who:
    • Maintain and configure voice and data network devices
    • Are considering various methodologies to implement VoIP
    • Require a fundamental understanding of the issues and solutions related to implementation
    • Require a fundamental understanding of packet telephony technologies that are common for both enterprise and service provider applications

Why use us?

Every pod has internal and external phones, and just like in a real network, the same simulated public switched telephone network (PSTN) is accessible through all four clusters providing failover scenarios for bandwidth and connectivity problems. To more accurately reflect real-world scenarios, different area codes are deployed at all sites (two per cluster), and you will configure the gateway connections to simulated PBX systems.

We have set ourselves apart from other Cisco training providers by enhancing our CVOICE hands-on labs to include a real dial plan and Class of Service for calling out to the PSTN, branch offices, and PBXs. Our voice network labs use the latest hardware and software so you will gain experience with the recent stable IOS release (15.0(2) currently). Plus, every router has 2xFXS, 2xFXO, and 2xT1 ports (PRI and T1-CAS) as well as serial ports for WAN connectivity. All of our IP telephony courses provide a realistic simulated PSTN accessible through both PRI and FXO ports.

You will build and test a real dial plan including:

  • 911
  • 3-digit service codes: 411, 511, etc.
  • 7-digit local numbers: 681-1901
  • 10-digit local numbers: 416-681-1901
  • 11-digit long distance numbers: 1-733-802-1901
  • International numbers: 011441902
  • Configure and test all dial peers as appropriate
