Cisco Voice over IP v5.0

This lab bundle lays the foundation for gaining significant hand-on skills and mastering of Cisco packet voice technology. You will configure and monitor basic packet voice functions and all major call control signaling scenarios on Cisco voice gateway technology. These labs involve the available Cisco packet voice configuration and troubleshooting tools to train you on how to use the tools to accomplish your everyday tasks.

The knowledge delivered here is essential to develop proficiency in the packet voice by starting at its basics and gradually building up to the true voice professional level.

This set of lab exercises contains the following exercises:

Objectives

Upon finishing this set of exercises, you will be able to:
Identify default voice port settings

  • Customize and verify analog port operations
  • Create, customize, and verify digital port operations
  • Configure dial peers for locally terminated calls, PBX calls, and PSTN calls
  • Determine appropriate method of digit forwarding and manipulation
  • Create hunt groups and determine their behavior
  • Simulate auto-attendant functions through the use of the PLAR and PLAR off-premises extension (PLAR OPX) features.
  • Create a Tie-line connection for calls between two PBXs.
  • Use appropriate show and debug commands to monitor and troubleshoot these special connections.
  • Configure VoIP connections
  • Describe how dial peer matching occurs
  • Describe and configure proper use of dial peer codec parameters
  • Verify basic call setup through debug commands
  • Use appropriate show and debug commands to monitor and troubleshoot basic VoIP
  • Configure single-zone and multi-zone H.323 gatekeeper environments for VoIP scalability
  • Use debug and show commands to monitor the status and progress of call setup procedures in an H.323 environment
  • Configure dial peers to use SIP call control procedures to set up VoIP calls
  • Use debug and show commands to inspect SIP call control procedures
  • Configure your router as an MGCP residential gateway and utilize the preconfigured MGCP call agent to establish voice calls
  • Use debug commands to analyze the interactions between MGCP gateway and the call agent
  • Use show commands to view the status of MGCP endpoints, connections and calls
  • Implement quality improvements on low-speed links with the QoS features, such as fragmentation, interleaving, and Frame Relay traffic shaping automatically configured using the AutoQoS
  • Implement features such as voice packet marking (tagging) and queuing automatically configured using the AutoQoS to improve voice quality end to end
  • Confirm, by testing, that the QoS features automatically configured by the AutoQoS, contribute to overall improvements in voice over data preference
  • Limit the number of concurent calls on a dial-peer
  • Implement RSVP as fundamental part in IntServ QoS arhitecture
  • Apply CAC on gatekeeper in H.323 networks
  • Verify CAC through show and debug commands

Importance

This lab bundle is recommended for all Enterprise and Service Provider engineers who deploy packet voice solutions based on Cisco voice gateways.

Target Audience

System engineers, field engineers, packet voice networks architects.

Prerequisite Knowledge

To fully comprehend the concepts and technologies delivered throughout this lab bundle, a working knowledge of LANs, WANs, and IP switching and routing is essential. Basic internetworking skills taught in the Interconnecting Cisco Network Devices training course, or equivalent, is considered the minimum knowledge needed for these labs. Although these are packetized voice labs, basic knowledge of the traditional PSTN operations and technologies is required.
