Course Overview

Course in a Nutshell

This course, intended to meet the requirements of the CompTIA Convergence+ certification, will help you take advantage of the growing demand for VoIP professionals. This certification is an internationally recognized vendor-neutral standard for validating voice/data networking skills.
Historically, voice and data networks have evolved separately, using circuit-switched and packet-switched technologies, respectively. However, the advances in digital signal processing have opened the door to an era where data networks, telephony, telecommunications, video, audio, teleconferencing, wireless, and broadcast multimedia technologies have “converged” into a single IP-based delivery system. This advanced networking course is aimed at those who wish to gain an in-depth understanding of a broad array of evolving converged technologies issues such as voice transmission principles, telephony, end point devices, QoS, coding techniques, protocols, network hardware, and security.

 

Customize It!

We can customize this course at little-to-no additional cost to the distinct needs of audiences such as network design and optimization engineers, designers of applications for converged networks, and VoIP vendors and service providers. We can also tailor it to the needs of less technical audiences such as executives, business planners, sales/marketing specialists, and operations/support personnel.

Audience / Prerequisites

Aimed At

I/T and telecom professionals who are responsible for designing, implementing, and managing converged voice/data networks.

 

Prerequisites

You should have a couple of years of experience in the IT industry and be familiar with IP networks and protocols. The Network+ Certification course is a recommended prerequisite.
