FXS (Foreign Exchange Station)

An FXS (Foreign Exchange Station) is a device that allows traditional landline phones to connect to a VoIP (Voice over Internet Protocol) system. It converts signals from a conventional telephone into digital data that can be transmitted over the internet, enabling standard phones to make and receive calls through a digital network. Essentially, it acts as a bridge between analog phones and modern digital communication systems, facilitating seamless voice communication in environments that use internet-based phone services.
