Megaco Essentials *** Duration: 2 days

Course Content

Megaco is emerging as a solution favoured by carriers. It is an IP based, call-control signalling protocol for mutlimedia. This course provides a detailed analysis of the mechanisms, processes and procedures employed by Megaco for media to control inter gateway exchange.

Course Objectives

Understand architecture, components and functions of Megaco

Describe the Connection Model and Media Gateway to Media Gateway Controller call flow

Identify security considerations for Megaco implementation

Who Should Attend

Pre-, post sales and support engineers

Engineers, technical professionals and planners from carriers, system vendors and integrators or end-users developing or deploying real-time services over IP networks

Prerequisites

Delegates must be familiar with basic telephony technology and have an understanding of TCP/IP such that as that provided by Voice-Technologies TCP/IP seminar
