Government departments were facing a wide range of challenges such as budget constraints, fragmented communication tolls, high and unpredictable costs, need for improved security, amongst others.

FourNet worked closely with Avaya and were able to develop a bespoke OPEX model that provides the flexibility and cost-effectiveness needed by the PMO.
The ANTENNA service gives users the ability to scale up and down quickly providing best-in-class and security cleared service management, ensuring the service exceeds expectations and continuously improves to meet changing requirements.


“The experience of working with FourNet on the ANTENNA project has been excellent. Transformation projects are never easy, and you have to be realistic about the challenges. But by working together in true partnership, our teams have achieved the implementation of unified communication services across Government within a timescale not seen before.”

"The Prime Minister's Office has worked in close partnership with FourNet to provide a ground-breaking shared service, ANTENNA to other Public Sector organisations. The new service, an Avaya private, secure, cloud-based Government hosted telephony service that currently supports a customer base of around 6,000 users, has the potential to save millions of pounds of taxpayers money by reducing costs for OGD's (Other Government Departments) and reusing assets across Government. FourNet has created a secure support team to work with the PMO IT team to deliver ANTENNA and has consistently demonstrated the highest levels of support and innovation."
