VoIP and Unified Communication-Course Overview

We begin the course with a history lesson, understanding how and why VoIP or as how it is cost effective. We will establish a basic model of VoIP and understand its main components: Terminals, Applications, Codecs, gateways, protocols and network operations.

Next, we will cover aspects of VoIP and UC, including its protocols TCP/IP, DHCP, RTP, RTCP,H.323, SIP, H.248. Then, we’ll take a brief look of how we move from PSTN to VoIP.

We’ll look into details of UC and its components, including signalling gateways, translator, codecs and protocols

On completion of this course, you will be able to draw a model of the VoIP and UC system, identify all of its components and technologies and explain the characteristics and operation of VoIP, the principal service.
