VoIP lines, or Voice over Internet Protocol lines, are communication channels that transmit voice and multimedia content over the internet using digital packets of data. Unlike traditional phone lines, which relied on analog signals, VoIP lines convert voice signals into digital data and transmit them over IP networks.

VoIP technology allows users to make voice calls, video calls, and send multimedia content over the internet, offering numerous benefits such as cost savings, flexibility, and enhanced features. VoIP lines are commonly used for both personal and business communication and can be integrated with various devices such as computers, smartphones, and IP phones.

Businesses often use VoIP lines to set up phone systems that offer features like call forwarding, voicemail-to-email, conferencing, and more. As technology continues to advance, VoIP lines play a significant role in shaping modern communication by providing efficient and versatile communication solutions.
