Service gateway ESR-12V

The solution for small and mid-sized offices
FXS ports for analogue phone connection
FXO port for connection redundancy
Firewall and router functionality

Service gateway ESR-12V router is designed to use in corporate networks for small and mid-sized offices connection.
The Firewall and router functionality provides security of different types of Internet connection.
ESR-12V has FXS ports for connection of up to 3 analogue phones to a corporate network without gateways. FXO port allows redundancy of phone connection via analogue line in case of lack of connection to central PBX.
