Voice over IP (VoIP) refers to the technology that allows telephone calls to be made over the internet instead of through traditional landlines. VoIP converts analog voice signals into digital data, which can then be transmitted over the internet using an IP network.
VoIP offers several advantages over traditional landlines, including lower costs, increased flexibility, and a wider range of features. VoIP is particularly beneficial for businesses that need to make frequent long-distance calls or that have employees who work remotely.
