VOIP Telephony


We provide reliable, flexible and scalable VoIP telephony solutions including Gamma Horizon and 3CX. Want to see more? Take a look below.

Hosted Telephony

We can host your telephone system in the cloud, whether that be on IT3000's cloud platform or with a public cloud provider, such as Azure, AWS or Google.

On Premise Telphony

If a cloud solution is not right for your business, we can also offer on premise VoIP solutions. Whether this be on your own hardware onsite or in our datacentre.

VoIP Telphony

With the UKs analogue ISDN/ PSTN network being switched off in 2025 it is no surprise that all of IT3000's telephony solutions use VoIP technology. 

SIP Trunks

A SIP trunk is the modern equivalent of a T1 trunk and connects to your VoIP phone system. With the end of ISDN/ PSTN all phones lines will be delivered in this way.

Modern VoIP Communication from IT3000

Communication is key with any business and having a reliable, flexible and scalable phone system is essential, especially as remote or flexible working environments become more common. We work closely with Circle Loop, Gamma Horizon and 3XC to offer tailored hosted and on premise VoIP telephony solutions, but we can also work with you to support any existing phone systems you may have in place.

Telephony Services from IT3000

Although we can work with a wide range of telephony providers, we have partnered Gamma Horizon and 3CX as between them we believe they offer our customers a wide range of features, customisations and price points.

The benefits for your business


VoIP telephony solutions can be extremely customisable and we can tailor these to your business' needs. Gamma Horizon providers a wide range of bolt-ons to customise your solution and 3CX comes with a large feature set straight out the box.


Your businesses requirements will change and evolve over time and with a VoIP telephone solution it couldn't be easier to scale your system up or down. In terms of users, lines and in some cases features, such as confercing or call recording.

Work anywhere

As VoIP telephone systems use the internet to make and receive calls your users will be able to use traditional handsets, softphones on a PC or laptop or even a mobile client on their iPhone or Android phones, meaning they really can work from anywhere.
