What is the primary function of Voice over Internet Protocol (VoIP)?

Voice over Internet Protocol (VoIP) is primarily designed to allow voice communication over Internet Protocol (IP) networks. This technology transforms voice signals into data packets that can be transmitted over the Internet. The fundamental advantage of VoIP is that it enables voice calls to be made using broadband Internet connections instead of traditional phone lines, which can lead to reduced call costs and increased flexibility in communication.

VoIP operates by digitizing the voice audio, breaking it into packets, and sending these packets over the network. The technology supports a range of communication methods, including both one-on-one voice calls and conference calls. This distinctive capability is what sets VoIP apart as an essential component of modern telecommunications.

In contrast, while video conferencing, high-speed Internet, and file sharing are functionalities that can exist alongside or as additional features in some Internet-based communication systems, they do not capture the core purpose of VoIP, which remains centered on enabling voice communication.
