Fixed-line telephony refers to traditional telephone services that use physical wires or cables to connect calls. This system typically involves a landline phone connected to a network through copper or fiber-optic cables. It allows users to make and receive calls from a fixed location, such as a home or office. Despite the rise of mobile phones, fixed-line telephony remains important for many households and businesses. It often provides more reliable service and better sound quality than mobile telephony. Additionally, fixed-line connections can support other services, such as internet access and television, through the same infrastructure.
