Introduction to VoIP
The course focuses on theoretical principles of Real-Time Media over Internet Protocol that use RTP (Real Time Transport Protocol) and RTCP (Real Time Transport Control Protocol). During this course both SIP (Session Initiation Protocol) and H.323 VoIP signalling systems will be discussed. This training course is designed to be generic, but examples of vendor specific Voice over IP systems will be mentioned.
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.
None, although some prior exposure to IP, Data Networking or Telecommunications would be advantageous.
