Why is it special?

We integrate our service with mobile carrier networks. In opposite to app-based or over-the-top (OTT) services, the 23numbers system does not require any VoIP client or app; your phone just rings if someone dials a phone-number you received from 23numbers. There’s also no app required to make things work – and no data connection. It works with a plain and simple feature phone as well.

This approach is based on APIs and components from leading manufacturers for telecommunication and carrier equipment like Nokia / Alcatel-Lucent or Ericsson – and of course on our experiences with these systems and – even more important – the technical and sales teams of these globally acting companies.
