voice & telephony

VOIP or Voice Over IP is a telephone communication system that uses the internet to transfer your telephone call data

The UK’s best VOIP hosted platform

In partnership with Southern Communications, our award-winning UK telecoms partner, RedKeyIT will manage the relationship for you to provide both a bespoke solution designed to your exact requirements and manage all ongoing issues and maintenance.


Our leading ‘Evonex’ hosted VoIP telephony platform is built on one of the most reliable hosted platforms, with built in resilience at all levels. It provides fast, reliable and efficient communications across a dedicated network, tailored to the needs and usage of your business, whether small, medium or large. Evonex is one of the most feature rich systems on the market, yet intuitively and easy to use, and delivers all the features you need to keep in touch with your customers and staff.


Simplify communications with Evonex and enable your mobile device to be an extension of your telephone system. Use just one number, present your office number from your mobile, ring multiple devices at the same time, use your desk phone from your home office and benefit from the convenience of Instant Messaging.


The Evonex phone system operates in the cloud, which removes the need for costly physical hardware on-site and analogue or ISDN telephone lines from phone providers. Instead, your business phone system is hosted remotely and connected to via the Internet. Essentially, the phone system becomes a piece of software rather than hardware, bringing with it savings in office space, on costly maintenance and upgrades, and easily scalable to the growth of your business.


What’s more, in 2025 BT will be switching off all ISDN (Integrated Services Digital Network) services related to  PBX systems, and as early as 2021 will stop selling PSTN and ISDN products in a further 117 exchanges from June 2021. Hosted telephony will future proof your telephony platform, as well as provide resilient backup and disaster recovery benefits.
