Digital telephones are communication devices that convert sound into digital signals. This technology allows for clearer voice quality and more efficient transmission over various networks, including the internet. Digital telephones can connect to both traditional phone lines and modern Voice over Internet Protocol (VoIP) services, making them versatile for personal and business use. These phones often come with additional features such as caller ID, call waiting, and voicemail, enhancing the user experience. Many digital telephones also support conference calling and can integrate with other digital devices, allowing for seamless communication in today's interconnected world.
