Cloud & VoIP

We specialise in the latest cloud and VoIP technology, providing voice connectivity on a monthly per-user cost model. Nexus IP have a long history in PBX business telephony and were an early adopter of the VoIP model, bringing it into our portfolio in 2005.

When delivered correctly, VoIP is a powerful business tool that can reduce costs, improve business communication, and deliver a more cohesive customer experience.

Handsets & Headsets

As part of our portfolio of equipment supplied to our clients, Nexus IP provide handsets, headsets, call logging, and call recording systems, battery backup systems, network switches and routers, wireless access points, and public hotspots, to name a few. We regularly review suppliers and vendors to ensure the products we offer are suitable and futureproof. All new products are run on bench tests within our laboratory and used by our own staff prior to adoption into our portfolio. This ensures that we know first-hand how the product performs, and how to support it.

We are so pleased that the install went well and would like to once again thank you so much for your professionalism and support, making the process so straight forward.
