With 17 years of experience in telecommunications, UnitedTech’s passion to be recognized as a trusted partner in business communications solutions is enveloped in our clear objective to create long term sustainable value.

Nexys was born out of a deep desire to simplify communications for companies. As a provider of business communications solutions, our objective at UnitedTech is to create long term sustainable customer value.

From the sale of high-speed fibre internet, to our integrated communications and Cloud Unified Communications (UC) solution – Nexys CLOUD, we remain committed to making communications simple. Our converged network solutions are designed to deliver flexibility, low total cost of ownership and total customer satisfaction.

The aim is to empower your team to access information faster, communicate from anywhere, any time, on any device and collaborate more easily.

A ‘cloud service’ refers to a wide range of services delivered on demand to companies and customers over the internet. Nexys CLOUD was designed to provide easy, affordable access to cloud communications, without the need for you to spend on internal infrastructure or hardware.

The Nexys CLOUD service was built in Teraco Data Centre in Isando, Johannesburg. Teraco forms a vital part of the African Internet’s backbone and is an essential part of the modern enterprise’s digital transformation strategy due to its world-class data centre infrastructure and network dense ecosystems.

Nexys CLOUD was designed to support numerous third party handsets, including Yealink, Polycom and Snom to name a few. If you would like to know if we can support your existing hardware, please let us know so we can see how we can help you.
