VoIP (Voice over Internet Protocol) is a technology that enables phone calls to be made over the internet rather than traditional copper phone lines, converting analog voice signals into digital packets for transmission. It allows calls from computers, smartphones, or special VoIP-compatible phones, using your broadband internet connection instead of a dedicated phone line. VoIP offers features like call forwarding, hold, and conference calls, and it’s becoming the standard for both businesses and personal use due to its flexibility and cost-effectiveness.
