Technology Details

As the size of an organization expands, the technical needs of the range of employees in that organization increases significantly. Managing a mixed estate of telecommunications platforms, across multiple buildings, locations, or even countries becomes increasingly challenging, from an efficiency and cost perspective. If there was a way to simplify, aggregate, and virtualize a percentage of those DECT resource needs, that would make the management of that section of the estate significantly easier, quicker, and more cost-effective.

There is another way…

With our VIP-DECT Server One you are able to adapt dynamically to organizational communication changes with, instant scalability of DECT base stations, high-capacity call throughput and availability, and flexibility in hardware platform choice.

Software-only IP-DECT architecture allows you to flexibly connect distributed enterprise sites creating a single virtual network with a common point of control for reliable, scalable communication delivery.


  • Scalability as your business grows. A fully virtualized VIP-DECT Server enables installation in any data center with the capacity to serve up to 100,000* users across large campus environments and distributed business sites.
  • Optimize resources and reduce workloads. Manage multiple sites, push new DECT features, add or remove users, and perform administrative functions all from a single centralized web portal.
  • Reduce hardware costs. Add more efficiency and savings to your business by using your current data center servers; consolidate the number of DECT servers needed.
  • Reduce maintenance and support costs. No need to go on-site to update firmware; manage your entire DECT network from one location.

* NOTE: Up to 100K handsets supported when combined with AMIE
