Introduction to Voice over IP

The course focuses on theoretical principles of Real-Time Media over Internet Protocol. Although the course is intended to be ‘generic’, examples of VoIP networks are highlighted utilising Cisco’s Callmanager platform and associated Networking devices.

 Prerequisites

None, although some prior exposure to IP, Data Networking or Telecommunications would be advantageous.

 Aim:

To provide delegates with a fundamental understanding of how voice and multimedia is delivered using packet switched IP networks, and to highlight the measures taken to make it possible.
Objectives:

By the end of the course delegates will be able to:

•  Understand how VoIP protocols have been integrated with existing TCP/IP Core Protocols.

• Be able to explain the reasons for the development of VoIP.
• Describe the potential benefits of VoIP.
• Understand voice quality issues such as latency and jitter when associated with VoIP.
• State the function of the real time protocols RTP and RTCP.
• Understand the differences between H.323 and SIP when used for the setting up, teardown and signalling for VoIP calls.
• Understand Quality of Service (QoS) and what it means, particularly in relation to Voice and multimedia over IP.
• Appreciate how IP Multicasting plays a part in the Real-Time media delivery.
