FXO VoIP Gateway to turn (PSTN) and IP-based communication systems.
An FXO VoIP gateway, also known as a Foreign Exchange Office VoIP gateway, is a device that enables the conversion between traditional analog telephone lines (FXO ports) and Voice over Internet Protocol (VoIP) networks. It acts as a bridge between the legacy Public Switched Telephone Network (PSTN) and IP-based communication systems.
