What is a "VoIP phone"?

A VoIP phone, or Voice over Internet Protocol phone, is a device that allows users to make voice calls using the Internet rather than a traditional telephone line. It works by converting sound into digital signals, which are transmitted over the Internet to the recipient’s VoIP phone, where the signal is converted back into sound. VoIP phones are often used for both personal and business communication due to their lower cost, flexibility, and ability to integrate with other Internet-based services. They can be used with special hardware or through software applications on computers and smartphones.
