The technology that enhances voice communication over the Internet is known as Voice over Internet Protocol (VoIP). VoIP converts analog voice signals into digital data packets transmitted over IP networks, allowing for clear and cost-effective communication. This technology enables users to make phone calls using their internet connection instead of traditional telephone lines. Features like video calling, conferencing, and messaging can also be integrated into VoIP systems. With advancements in internet speeds and reliability, VoIP has become increasingly popular for personal and business communication, offering flexibility and scalability.
