Internet Telephony refers to the technology that allows voice communication over the Internet, primarily using Voice over Internet Protocol (VoIP). This method converts audio signals into digital data, enabling users to make phone calls through their computers or smartphones without traditional phone lines. The rise of Internet Telephony has transformed how people communicate, offering cost-effective solutions for both personal and business use. Services like Skype and Zoom exemplify this technology, allowing users to connect globally with ease and convenience, often at little to no cost compared to conventional phone services.
