Duration

5 days

Overview

In this course, you will focus on the legacy gateway and router portions of IP Telephony. You will gain extensive experience with the configuration of legacy analog telephony technologies such as Foreign Exchange Station (FXS), Foreign Exchange Office (FXO), and Primary Rate Interface (PRI). In addition to legacy technologies you will gain hands on experience with CUBE and SIP protocols. You will build a working Cisco Unified Communications Manager which will support all major gateway protocols such as MGCP, H.323, and SIP.

WHO SHOULD ATTEND?

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

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
  • 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 and explore their DSP configuration (PVDM3 cards)
  • Configure H.323 gateways and review their functions and operation
  • Configure Session Initiation Protocol (SIP) and Media Gateway Control Protocol (MGCP)
  • Experience G.711, and G.729 voice coding schemes
  • Configure Call Admission Control three different ways
  • Configure proper Caller ID
  • Experience real-world connections to PBXs, and the PSTN
  • Configure your router/gateway equipment to connect to our public dial plan network using different call control protocols and procedures
