P-VOIP1

Duration

3 day(s)

Aimed At

This course is aimed at telecommunications and IT professionals who are responsible for planning, procuring, designing, implementing, and managing converged voice/data networks.

Prerequisites

You should have two years of telecommunications and/or IT experience. You should also be familiar with IP networks and protocols.

Course in a Nutshell

While voice networks use circuit-switched technologies, data networks employ packet switching. However, advances in Digital Signal Processing (DSP) have ushered in a new era where telephony, telecommunications, wireless communications, broadcast multimedia technologies, data networks, audio, video, and teleconferencing are all “converging” onto a common IP-based delivery platform. This VoIP networking tutorial is aimed at those who wish to acquire an understanding of the voice transmission fundamentals, endpoint devices and dialing plans employed in a converged network, Quality of Service (QoS) and network performance issues, networking technologies and coding techniques, and convergent applications. This course, along with its sequel, P-VOIPADV1, intended to meet the requirements of the CompTIA Convergence+ certification, will help you take advantage of the growing demand for VoIP professionals.
