Lesson Objectives

Designing for Optimal Voice Quality

  • identify the factors present in IP networks that affect audio clarity.
  • identify the problems presented by jitter, delay, and packet loss in an IP network, and recognize how Cisco deals with each of these problems.
  • distinguish between voice quality measurement standards and recognize why PESQ is the preferred method of testing voice quality in VoIP networks.
  • recognize the objectives of QoS and identify the network areas in which QoS is used to improve voice quality in Cisco networks.
  • identify the characteristics of a poorly designed network, and list the QoS deployment and configuration tasks automated by Cisco AutoQoS.
  • configure AutoQoS in a given network scenario.
