VoIP - Voice over Internet Protocol
VoIP is a revolutionary technology that has the potential to completely rework the world's phone systems.
VoIP systems are commomnly used for business telephone systems because they are cost effective and have many more features than conventional land lines.
In general phone service via VOIP costs less than equivalent service from traditional sources. This is largely a function of traditional phone services either being monopolies or government entities. There are also some cost savings due to using a single network to carry voice and data. This is especially true when users have existing under-utilized network capacity that they can use for VOIP without any additional costs.
VOIP makes easy some things that are difficult to impossible with traditional phone networks. Incoming phone calls are automatically routed to your VOIP phone where ever you plug it into the network. Take your VOIP phone with you on a trip, and anywhere you connect it to the Internet, you can receive your incoming calls. Call center agents using VOIP phones can easily work from anywhere with a good Internet connection.
