VCS over IP


Download Leaflet


To meet the « all over IP » paradigm, while adhering to the Eurocontrol and ICAO regulatory requirements, our radio/telephone systems, meant for the security communications of air-traffic controllers, transition to VCS over IP (Voice Communication Switch over IP networks).

Communicate at all costs

Whatever the circumstances, air-traffic controllers must have at their disposal a radio/telephone system providing them with the ability to communicate right away with aircraft, local teams or the neighboring control towers or centers.


Technology plus flexibility

Specifically designed for small or midsize airports and control centers that are set in severe environments, AIRvoice provides you with a high level of availability.

Through its configurable touch screen interfaces, it meets the telecom (radio, telephone, intercom) needs of the most demanding air-traffic controllers. It also constitutes a component of our AIRview integrated tower console.

By preserving your existing infrastructure, AIRvoice allows for a smooth migration from your current telecom system to the VoIP (Voice over IP) technology, as per the Eurocontrol (ED 137) and ICAO interoperability recommendations. AIRvoice meets the specifics of narrowband networks and satellite telecommunications while guaranteeing optimal voice quality.

Keep track of your communications

Abiding by the ICAO recommendations, the very high availability is rooted in the genes of AIRvoice :

  • Hardening and redundancy of equipment, power supplies, network links, software, and automatic management of backup links.
  • Your IP communication network is protected from intrusions. Users are authenticated through profile and permissions.

Conforming with Eurocontrol (ED 137) interoperability requirements, AIRvoice incorporates all of the analog, digital and IP radio and telephone interfaces. It is able to exchange data with all your IP systems.
AIRvoice accommodates the voice compression algorithms to offer the finest hearing quality, even over narrowband networks or in satellite telecommunications.
