Design of Voice over IP Networks
This 2-day programme 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.
