Integration with the exchange
- Connection to the plant telephone exchange
- Calls between zones
- Direct connection with the control room, rescue services, and management
When things go wrong, especially in hazardous zones, only one thing matters: can you get through in time? ATUT‑VoIP provides clear, uninterrupted communication across the entire designated space of the industrial plant, from explosion‑hazard zones to the control room or decision centre.

Without communication, there is no safety. When you need to connect with a specific person or group, especially in a hazardous zone where a standard telephone cannot cope—whether underground or in special zones—only devices and a system designed for such specific operating conditions will succeed.
ATUT‑VoIP provides modern voice communication throughout the plant. It connects to the plant's telephone exchange, so you talk freely between zones and connect with monitoring, automation, safety, and warning systems.
The equipment withstands dust, moisture, shocks, and high temperatures. Operation is as simple as a standard telephone, and the system grows alongside the plant zone. The result: increased safety, more efficient management, and lower costs.
