VoIP, or Voice over Internet Protocol, is fundamentally a methodology for delivering voice communications over the internet or through other packet-switched networks. It converts analog voice signals into digital data packets, which can then be transmitted over the internet. This functionality allows users to make voice calls using internet connectivity rather than traditional circuit-switched telephone networks.

This answer emphasizes the service's unique capability to facilitate real-time voice communication, underscoring its role in modern telecommunications. By utilizing internet infrastructure, VoIP represents a shift from traditional calling methods, making it a critical aspect of contemporary voice communication solutions.

In contrast, options referring to video streaming, wireless networking standards, or data transmission protocols do not capture the specific nature of VoIP as a voice communication methodology. VoIP is explicitly designed to handle voice traffic efficiently, which differentiates it from those other protocols and services.
