On 20 November 2014 STENTOFON and VINGTOR merged into Vingtor-Stentofon. STENTOFON is a brand of integrated security intercom systems. STENTOFON is owned by Zenitel Group, headquartered in Belgium. These systems are aimed at onshore installations as the parent company Zenitel also offers off shore products under the brand name Vingtor. Another sister brand under Zenitel is ChuChubi, Zenitel first offered Network services in 1993 and introduced the ChuChubi brand name in 2004. The name is now so well known in the Caribbean and in the Netherlands Antilles that people today do not speak about their "portable" or their TETRA radio, but refer to their radio as their ChuChubi Zenitel brands Stentofon have offices in Singapore, France, the Nordics, Italy, Germany, Croatia and the USA, and two joint venture companies in the UK and China. Their main office is in Oslo, Norway. STENTOFON is also represented worldwide by a network of partners.
Stentofon or Zenitel as we see it today is an amalgamation. Stentofon began life in 1946 as Stentor Radiofabrikk, specializing in radio communication systems for ships and for fishing boats. Stentor later extended its range with intercom systems that it sold under the brand name STENTOFON. Also in 1997, Stentofon AS merged with another Norwegian supplier of internal communication systems and provider of PMR-systems, RingCom AS, itself the result of a merger between Ring-Master and Noracom. Ring Marine AB in Gothenburg also joined the group. The Stentofon and RingCom amalgamation was called Stento ASA
STENTOFON specialize in niche markets such as oil platforms, hospitals, public transportation or tunnels that require secure communication.
