ng-voice was founded in 2011 by a small team of leading open-source, VoIP pioneers and passionate coders to develop innovative software solutions for fixed and mobile network operators, containerized from scratch. ng-voice’s founder and CTO, Carsten Bock, is one of the VoIP industry veterans. He believed in VoLTE becoming the new mobile voice standard when it was still a niche technology.

Since then, the telecom business has completely changed. Driven by exploding data usage and emerging technologies, the demand for flexible software-based network infrastructure has increased. In 2019, David Bachmann, a former Associate Partner at McKinsey, joined ng-voice both as CEO and shareholder to drive ng-voice’s commercialization and growth strategy, and long-term investors came on board. To increase supplier diversification and foster innovation in the European 4G/5G ecosystem, ng-voice also founded EANGTI, the European Association of Next Generation Telecommunications Innovators.

ng-voice has focused on turning our IMS core into the most cloud-native IMS solution in the market, being fully containerized and deployed with Kubernetes. We have also developed and launched several 100% cloud-native virtual network functions in addition to the IMS core, such as our application servers and ePDG. Basit is leading ng-voice’s cloud-native transformation, delivering a very unique value proposition for our solutions, with the smallest container sizes, a high level of automation, and efficient use of resources.

In addition, ng-voice has invested in new technologies, cutting-edge companies and partnerships, and has recruited an A-team of experts coming from the most relevant telecom players and also from the research field, such as Johanna, that joined the company bringing her experience in 5G Core research.
