A telefonanschluss IP, or IP phone line, is a type of telephone service that uses the internet to transmit voice calls. This is in contrast to traditional phone lines, which use a physical copper wire connection.
IP phone lines offer a number of advantages over traditional phone lines, including lower costs, greater flexibility, and more features. For example, IP phone lines can be used to make calls from anywhere with an internet connection, and they can be easily integrated with other business applications, such as customer relationship management (CRM) systems.
