What is an FXO Gateway and how does it work?
-
An FXO Gateway is a telecommunications device that connects a VoIP (Voice over IP) network to the traditional Public Switched Telephone Network (PSTN) by utilizing FXO (Foreign Exchange Office) ports. Essentially, it allows businesses to use VoIP systems while still being able to make and receive calls through the PSTN.
When a call is placed or received, the FXO Gateway acts as an interface between the two networks. It converts the voice signals from VoIP into a format that can be transmitted over the PSTN, and vice versa. This makes it ideal for businesses that want to integrate modern IP-based communication with existing landline systems.
FXO Gateways typically come in multiple port configurations (e.g., 2-port, 4-port, 8-port) to cater to varying business needs, enabling multiple simultaneous calls. They also often support advanced features like call routing, faxing, and call forwarding, making them a versatile tool in any communication setup.
In summary, an FXO Gateway provides a bridge between traditional and modern communication systems, ensuring seamless connectivity for businesses that need both VoIP and traditional phone services.
