Final answer:
In Internet telephony, which is known as Voice over IP (VoIP), a dedicated phone line is not required, as this technology uses packet-switched networks to convert voice signals into digital data for transmission.
Step-by-step explanation:
All of the following statements regarding Internet telephony are correct except: It requires a dedicated phone line. Internet telephony, which is also known as Voice over IP (VoIP), uses packet-switched networks to facilitate communication. Unlike traditional telephony, VoIP does not require a dedicated phone line. Instead, it converts voice signals into digital data, mutually benefiting from improvements in broadband technology and offering cheaper, faster, and better-quality data transmission. The adoption of digital data for voice and video has led to spin-off technologies, such as free Internet-based calling and video calling, significantly lowering the cost of long-distance communications and enhancing consumer choice.
