Understanding VoIP: Foundations, Protocols, and Essential Components for High-Quality IP Telephony
What you will learn
Understand the Core Principles of VoIP and IP Telephony
Identify Key VoIP Protocols and Concepts
Understand and Work with VoIP System Components
Understand VoIP Call Flow and Network Performance
Why take this course?
This fundamentals course offers a basic understanding of Voice over Internet Protocol (VoIP) and IP Telephony, focusing on both the fundamental concepts and practical applications of this transformative communication technology.
The course begins with an introduction to VoIP and IP Telephony, explaining how voice data is transmitted over IP networks, and covers key terminologies and concepts such as SIP, RTP, Codecs, and Quality of Service (QoS).
You’ll then explore the core mechanics of VoIP, starting with how voice is converted into data packets for transmission. We’ll delve into key VoIP protocols like H.323, SIP, and RTP, which govern how calls are set up and managed across networks. A detailed look at the role of Codecs will help you understand how voice data is compressed for efficient transmission while maintaining call quality.
The course also covers the essential components of a VoIP system, including IP phones, VoIP gateways that bridge VoIP and traditional telephony, and the role of VoIP servers and PBX systems in managing call routing and features. You’ll also gain insights into codecs and the importance of network infrastructure and security in maintaining VoIP call quality.
Finally, the course provides a deep dive into the VoIP call flow, illustrating how calls are set up, negotiated, and transmitted across IP networks, and how network challenges like latency and packet loss are managed to ensure high-quality communication.
