Elevator Connectivity

Reliable elevator communication solutions designed for tomorrow’s smart buildings

Elevator connectivity is reshaping how buildings ensure safety, compliance, and seamless communication — bridging the gap between legacy voice systems and tomorrow’s smart infrastructure. Robustel delivers secure, reliable, and future-ready solutions that keep elevators connected for voice, data, and IoT applications. From replacing outdated PSTN/POTS lines with VoIP to enabling real-time monitoring and remote management, our hardware and cloud platforms ensure consistent performance in mission-critical environments. Backed by global deployments and trusted support, Robustel provides building operators and system integrators with the foundation for safer, smarter, and more efficient elevator operations.

Keep lifts safe, connected, and ready for inspection

Why Building and Lift Operations Teams Choose Robustel:

PSTN Switch-Off Ready

Replace copper lines with 4G/LTE IP while keeping the analog emergency phone experience intact. Our elevator voice gateway bridges FXS handsets to cellular or SIP so calls route reliably during and after migration.

One View of the Estate

With Robustel Cloud Manager Service (RCMS) you see online/offline status, signal, and data use across sites, push firmware and configuration by group, and open a secure CLI for deep work without rolling a truck.

Secure By Design

Segment car, controller, and building networks; keep remote access least-privilege and time-bound with RobustVPN; maintain an audit trail of changes. You control who connects, when, and to what.

Hardware That Fits Lifts

From compact cellular routers for controller rooms to the purpose built EV8100 Elevator Voice Gateway for emergency calling, our portfolio covers primary, backup, and migratory scenarios with clean integration into existing cabinets.

How Robustel Helps You Overcome Operational Challenges:

Use this as your quick map from requirement to control. We’ll supply detail and templates during scoping.

Copper retirement and VoLTE/VoIP migration
PSTN lines are disappearing, but emergency phones must work every time. We bridge analog phones to cellular or SIP and supervise call paths so you pass audits and protect users.
Unreliable coverage inside shafts and basements
Signal varies by building. Dual-SIM routers, approved antennas, and clear installation guidance raise call success and controller uptime.
Fragmented fleets and inconsistent change control
Different contractors, models, and sites make updates risky. RCMS templates, Zero-Touch provisioning, and ring-based rollouts make changes predictable and auditable.
Security and remote access concerns
Lift OEMs and service partners need periodic access, but IT needs control. We enforce segmentation and use RobustVPN for time-boxed, role-based sessions with a full activity log.

How the Pieces Fit:

Operations: RCMS provides monitoring, alerts, configuration templates, and remote actions. RobustVPN grants least-privilege maintenance access with audit.

In the shaft and machine room: Analog emergency phone connects to EV8100 (FXS). Controller, sensors, and cameras connect to an industrial router via Ethernet or serial.

Uplink: Primary 4G/5G or building WAN, with optional failover. Voice calls route via cellular (VoLTE/CSFB where applicable) or SIP; data traffic uses a policy-controlled path.
