Netherlands’ first cloud-based VoLTE and Wi-Fi calling network
Wanting Dutch customers to have the best possible voice services, VodafoneZiggo and Ericsson united to successfully install the country’s inaugural cloud-based, end-to-end voice over Long Term Evolution (VoLTE) and Wi-Fi calling solutions. VodafoneZiggo now has the world’s best voice quality score.
The opportunity
- Improve customer experience and satisfaction by introducing cutting-edge voice services over LTE and Wi-Fi
- To prove an even greater rival to other Dutch communications companies

When you want to innovate, there will be people who say: 'it's too early', 'it will not work' and 'it cannot work', but when you think there is a challenge and the whole industry needs to move in this direction, you say – let's take on the challenge.
