Voice over IP (VoIP) refers to the transmission of voice and multimedia content over the internet or other packet-switched networks. It converts analog voice signals into digital data that can be transmitted over the internet.
VoIP offers significant advantages over traditional phone systems, including cost-effectiveness, flexibility, and scalability. It enables businesses to make and receive calls over the internet, reducing phone bills and eliminating the need for expensive hardware and infrastructure. Additionally, VoIP allows for easy integration with other communication tools, such as video conferencing, instant messaging, and file sharing.
