Introduction to Voice Over IP (VoIP)
Overview Voice over Internet Protocol is one of the latest costs saving technologies available today. Most corporate bodies will have two types of network available to them, i.e. PSTN and LAN or an IP network. With the spiralling cost of international and national telephone calls VoIP technology enable the corporate, and, if required the private user, to re-route Voice calls over their, often under utilised, data network. Duration - 3 Days.
