Frequently Asked Questions

  • What are the advantages of a cloud telephone system?

    Cloudya, our smart communication platform, uses the Internet to make and receive calls. With NFON you eliminate the telephone system hardware, the telephone connection and the maintainer. The system is flexible, scalable and simple to administer.

  • What technology does Cloudya use?

    The base technology is called hosted PBX, often called IP Centrex. Both refer to the same concept: the telephone system is not installed at the company site but at an external data center, and can be accessed anywhere using the Internet.

  • How secure is Cloudya?

    The telephone system is operated over the Internet. The system itself is located at the NFON data center – it has a resilient set up failover at geographically separated servers. All services are guaranteed.
