Modern IP-Telephoning
The Cloud-PBX from vio:networks
With our cloud telephone system, also known as IP-Centrex or Hosted PBX, you can choose the PBX of the future and benefit from many advantages at the same time. We operate the virtual telephone system for you in our professional data centres in Berlin and Nuremberg. You purchase the Online-PBX as a service from the Internet.To use the software-based VoIP telephone system (VoIP stands for "Voice-over-IP") you do not need an analogue or ISDN telephone connection, but only DSL Internet access. That saves costs, because the investment in expensive hardware is void. In addition, the IP telephone system grows with the number of your employees, so that you only pay as much as you currently use.
The cloud telephone system also gives you maximum flexibility. You can use the telephone system to make calls from anywhere in the world with various extensions such as VoIP telephones, the computer or mobile with smartphones and tablets. From the basic functions of a telephone system to groups, voice menus and call center functions to modern unified communications our virtual telephone system offers you much more than you are used to from a telephone system.
The telephone system from the cloud is suitable for small and medium-sized enterprises (SMEs) with 3 or more employees as well as for large companies with up to 5000 employees.
