Description:

This 3-day program covers Voice over IP networks, one of the fastest moving technologies today.

Voice over IP (VoIP) is constantly evolving in the standards, protocols and manufacturers’ specifications, seemingly on a day-by-day basis. This course is designed to provide an introduction and technical overview of the competencies and practical requirements to install VoIP networks, within existing SME and corporate environments, as well as green field sites.

Designed for individuals responsible for assessing, selling and/or specifying VoIP systems, as well as PBX engineers seeking to migrate to new technologies. To successfully complete this course, participants should have a good understanding of LAN architectures and concepts and a basic knowledge of copper and fibre cabling systems.costly.
