Voice over Internet Protocol (VoIP), also called IP telephony, is a method and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. VOIP is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line.
With Voiceover IP, you can still call a landline or mobile phone, but you’ll be using your internet connection to do so, rather than a phone line connection. This can represent a solid alternative and can work out to be fairly cost effective.
VoIP has emerged as a popular alternative to a copper home phone line amid the rollout of high-speed fixed line broadband, Wi-Fi and mobile 4G, along with the rapid adoption of the smartphone. High speed internet access is virtually wherever we go and has enabled a whole new communications boom.
