A landline is a telephone service that uses physical copper or fiber-optic wires to transmit analog voice signals. It has been the standard communication method for decades, supporting phone calls, faxing, and security systems. It operates through the Public Switched Telephone Network (PSTN) and provides reliable voice communication.
With the rise of digital communication, landlines are gradually being replaced by VoIP and wireless solutions. However, some businesses and households still rely on landlines for reliability and emergency connectivity.
