IP telephony : internet telephony
Over the past two decades, companies have gradually adopted a new technological approach to replace conventional telephone network switches. This advancement is internet telephony, also known as IP (“Internet Protocol”) telephony.
In this approach, telephone communications no longer pass through the traditional telephone network, but use a computer network which relies on internet infrastructures such as ADSL, SDSL or optical fiber.
