The technology that facilitates the routing of voice communications over the internet is Voice over Internet Protocol (VoIP). VoIP converts voice signals into digital data packets, allowing them to be transmitted over the internet instead of traditional telephony. This innovation has drastically transformed communication by enabling free or low-cost calls, video conferencing, and other multimedia exchanges. VoIP services, such as Skype and Zoom, rely on internet connectivity, making them accessible and flexible for users across the globe, both in personal and professional contexts.
