Gamma Horizon

Horizon is a hosted business telephone service that resides in the cloud rather than your office. It provides an extensive range of fixed and mobile telephony capabilities accessed through an easy-to-use web portal.

The service allows you to easily manage your environment whilst enabling your employees to maximise their productivity. The emphasis is on control and administration that takes the burden of the IT team. As your organisation’s requirements change the system can be configured to adapt.

Horizon is a low-cost option for businesses of any size to improve its productivity and reputation.

Benefits of Horizon

Lower telephony costs

Horizon is hosted on your behalf so you only pay for what you need on a per-seat basis. Avoid major hardware or maintenance investments as you’re not buying a PBX. It also offers all the cost benefits of IP telephony including free site-to-site calls and cheaper call rates.

Enables flexible working

Enabling employees to work from anywhere is fast becoming the new normal. Horizon enables flexible work through hot-desking, home working and through us on mobile devices. With Collaborate (a Horizon bolt-on) you can provide employees with a fully unified comms solution.

Easy to install and maintain

You can have Horizon live within 24 hours with no need for IT assistance. Horizon also requires minimal ongoing support. If you do need support we have experienced engineers on hand to help you.
