The Norwegian Public Road Administration selected Norphonic Emergency Roadside Telephones for the new European road E18 between Kristiansand and Grimstad in Norway. The road construction project, covering over 345 kilometers, is the largest project ever completed in the South of Norway.

It took 38 months to complete and employed people from over 20 nations in the process. The road, which features 4 bridges and 7 tunnels, was recently opened by HRH King Harald of Norway, supported by Norwegian Minister of Transport and Communications Liv Signe Navarsete and the State Highway Director Terje Moe Gustavsen amid much public fanfare and local celebrations.

The new road system is built to very strict safety standards and the technology employed also needed to be esthetically pleasing to look at.

After an in-depth review of possible solutions, the Norphonic Heavy Duty VoIP Telephone was deemed the best Emergency Roadside Telephone (ERT) product due to its high performance capabilities, robustness and innovative product design.

A key criteria was that that the solution had to be able to perform in extremely challenging areas, exposed to dust, vibration and extreme weather.

Says Thomas Lyngtun Hansen, Technical Director at Norphonic ” funnily enough, even in Norway, the problem with the weather is not really the cold, but the heat. You will be surprised how hot it can be inside a SOS call box where the sun is shining in the summer months. Often it can get as hot as +50 degrees in the box during the day only for the temperature to drop drastically overnight.”

”In such environments it is important that the technology not only can handle hot temperatures, but also that the system is condensation proof, preventing the formation of water inside the unit. This could otherwise affect performance.”

Mr. Hansen concludes "we are pleased that our product provides a reliable operation in this very challenging area, and look forward to install our Heavy Duty VoIP telephones in other road construction projects in the future”
