In a rapidly evolving communication landscape, FXO (Foreign Exchange Office) and FXS (Foreign Exchange Subscriber) gateways serve as critical components that bridge analog and digital networks.
At CASQ, we proudly offer one of the most comprehensive portfolios of FXO and FXS gateways in India, catering to businesses of every size from startups to large enterprises.
What Are FXO and FXS Gateways?
An FXS gateway connects your VoIP system to analog devices, like telephones or fax machines. It sends dial tone, ring voltage, and call signals to the analog equipment.
An FXO gateway allows analog telephone lines (PSTN) to connect to VoIP networks. It receives the telephone line signal and passes it to the IP-PBX or SIP server.
Together, these gateways ensure smooth integration between legacy phone equipment and modern IP communication systems.
