Introduction to Voice over IP
This course has been designed to provide delegates with knowledge of the fundamental principles of Voice over Internet Protocol. IEEE standard H.323 and the Open Standard Session Initiation Protocol (SIP) are described and compared.
Prerequisites
A basic knowledge of TCP/IP.
Learning Objectives
At the end of this class, participants will be able to:
- Understand the reasons for the development of voice over data networks.
- Have an appreciation of factors affecting voice quality.
- Understand the IETF protocols developed to allow real-time media of data networks.
- Determine the function of the real-time protocols and where in the protocol stack they operate.
- Understand the elements and function of the ITU-T H.323 umbrella protocol.
- Understand the basic functions of the IETF Session Initiation Protocol and compare it’s operation to that of H.323.
- Differentiate between various Quality of Service (QoS) methods employed.
- Determine how Layer 3 Multicast addresses are mapped to Layer 2 Multicast addresses.
Who Should Attend
Network technicians, Technical Managers and Support Staff who need an overview of Voice over IP fundamentals.
