Robustel EV8100
Industrial VoIP Gateway for PSTN & POTS Line Replacement
The Robustel EV8100 is a compact, carrier-certified VoIP gateway designed for seamless migration from traditional PSTN (Public Switched Telephone Network) and POTS (Plain Old Telephone Service) lines to modern IP-based voice networks over 4G LTE. Built for industrial reliability, the EV8100 delivers secure and cost-effective voice connectivity for critical applications โ from elevator emergency phones to intercom systems, vending machines, and legacy alarm panels.
Featuring an FXS interface for plug-and-play analog device connection and dual SIM support for mobile network redundancy, the EV8100 acts as a drop-in replacement for analog lines where fixed-line access is unavailable or being decommissioned.
Trusted by elevator integrators worldwide and compliant with EN 81-28 and AS1735 standards, the EV8100 is the ideal VoIP gateway for telcos, OEMs, and system integrators modernizing their voice infrastructure.
