“Furthermore, the Norphonic Heavy Duty VoIP telephone has an excellent voice sound quality with a Mean Opinion Score of 4.3. Norphonic also have a long and successful track record, having been installed in numerous tunnels in the past”.

The ERT system is based on a Norphonic VoIP telephone without a keypad, allowing stranded motorists simply to lift the handset to be put straight through to the emergency services, eliminating the need for road users to remember what telephone number to dial in case of an emergency.

The Results

The robust Norphonic VoIP telephones will be installed in eight finished road tunnels in Iceland and also three others currently under construction in the Icelandinc road system.

The Norphonic VoIP Emergency telephones are based on open SIP standards and can therefore work seamlessly with any IP based PBX solution, in Iceland’s case a brand new Alcatel- Lucent Omni PCX Enterprise switchboard solution. The Alcatel solution has a full redundant system and a 12 hour battery back up which will automatically be deployed in case of power failure.

Since the Norphonic ERT telephones comes with remote control and automatic fault check features as standard, any maintenance or upgrade work can be done from a central location, reducing maintenance costs considerably.

Once the installation and replacement program is complete, the Iceland Road Administration will be able to manage all emergency roadside telephones in Iceland from one central control room.
