The Robustel EV8100 is a 4G voice gateway for lift emergency phones and other analogue voice devices losing their copper line. It connects the existing analogue phone through its FXS port and carries the call over the mobile network, with dual SIM failover and optional battery back-up, in a compact housing for desktop, wall or DIN rail mounting.

The EV8100 is built for the PSTN switch-off. Robustel states it complies with EN 81-28, the European standard for remote alarms on lifts, and with AS1735. Calls are placed as SIP VoIP, with VoLTE as a back-up voice line. Alongside voice it has RS232, RS485 and CAN serial ports, digital inputs and a relay, so the same unit can report lift status and faults, and it can be managed remotely through Robustel's RCMS cloud platform.
