Voice Over IP (VoIP) Training Course

Introduction

 In this course, you will learn core concepts of how the Internet Protocol (IP) carries a Voice over IP (VoIP) packet. You will learn the fundamentals of Session Initiation Protocol (SIP) architecture, SIP-related IP services, the advantages and disadvantages of SIP Trunking as well as Quality of Service (QoS)-Related Protocol.

Objectives

    What You'll Learn

    • Core concepts of how Internet Protocol (IP) carries a VoIP packet
    • Advantages and disadvantages of SIP Trunking
    • Understand how DHCP and DNS supports IP telephony
    • Real-Time Transport Protocol (RTP)
    • Session Initiation Protocol (SIP) – Call set up, Instant Messaging, Presence
    • Session Description Protocol (SDP)
    • SIP proxy, Session Border Controller (SBC), and SIP softswitch
    • Media Gateway Control Protocol (MGCP) analysis
    • MGCP architecture
    • How to implement QoS to ensure the highest voice quality over your IP networks
    • The impact of jitter, latency, and packet loss on VoIP networks
    • How Wireshark can decode and troubleshoot RTP, SIP, and MGCP call flows
    • Discuss trixbox Softswitch and SIP proxy
    • Discuss SIP gateways and softphones

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.

Who Should Attend?

This class is for people who need to understand VoIP technology. IT managers, technical sales/marketing personnel, consultants, network designers and engineers, product design engineers developing integrated-services products, telecom technicians and managers integrating PBX services within data networks, and systems administrators who will manage a converged network would benefit from this course.
