Main features of Horizon

The right connectivity is essential to delivering high-quality voice connectivity, simply sending voice traffic down your existing broadband can lead to degradation of service.

To prevent this we provide dedicated fibre connections or managed ethernet circuits with QoS (Quality of Service) routers to ensure you continue to receive the high-quality voice connections you require.

Horizon puts you in complete control of your phone system and is provided with an extensive range of call handling and management features, all operated through an easy-to-use web interface.

With a Horizon phone system, there is no need to change your telephone numbers when you move or when you have equipment at multiple sites.

Home, office and mobile workers can all be contacted as if they were all in one office, irrelevant of their physical location.

Horizon conveniently integrates your fixed and mobile capabilities so that you never miss a call. Callers need only dial one number to reach your desk phone and mobile phone simultaneously; ongoing calls can be moved seamlessly from one device to another without hanging up and a single voicemail box can be accessed from any device.

As Horizon is hosted on your behalf, you only pay for what you need on a simple per seat basis. As you are not buying a PBX, there is no major hardware investment and there are no financing costs to consider.

All the cost benefits of IP Telephony including free site-to-site calls (even across international boundaries) and cheaper call rates. If you use Horizon together with our mobile services you benefit from incredibly competitive rates for calls between your fixed and mobile devices.

Horizon helps businesses become more efficient by enabling flexible work environments through hot-desking, home working, and extending the service to mobile devices.

You have total flexibility with the numbers you want to use. You can keep your existing numbers or get new numbers. Extend your business reach and use any local area number no matter where you are located. Have a London number in Leeds!

Unexpected events such as snow, floods or strikes won’t disrupt your business. Because Horizon sits in the cloud, the service provides business continuity features that allow your organisation to carry on making and taking calls.

Horizon with preium handsets

Premium handsets plus desktop and mobile clients

Horizon is provided using Cisco or Polycom handsets, providing high standards of interoperability and features from manufacturers you know and trust. Unlike other solutions, an installation can combine manufacturers in any configuration to ensure the best handset is used for the customer`s requirement.

Horizon Web Portal and Clients

An easy-to-use web interface providing feature control and valuable user information

With an experienced in-house software development team, Gamma Horizon can provide a positive user experience for both service use and performance monitoring

Bringing voice to Microsoft Teams with one simple application

Horizon for Microsoft Teams enables your business to use Microsoft’s Teams application as a Horizon endpoint to make and receive telephone calls using Gamma’s Direct Routing capability.

This allows you to take advantage of your existing Microsoft infrastructure with Horizon to support complex business voice requirements, all provisioned within a simple application.

Horizon has a considerable number of integrations and a very useful TAPI driver as well, in fact we have so many that they need their own webpage, browse integration content.

You are able to link your desktop, office phone, mobile phone, Instant Messaging, CRM and other apps for a total unified communications solution, delivered by our network.

Yes, business is changing: Nine times out of ten we will be talking to IT managers. You hardly see telecoms managers in business any more as voice increasingly sits under the IT umbrella.

A huge amount – your organisation’s entire communications, across multiple sites and countries, can be managed easily, right down to the individual user level, through a simple interface.

There is no up-front spend on hardware or software plus hosted telephony means no costly PBX maintenance or upgrades as we are responsible for the hardware and software, including system upgrades. You can also access low-cost and free IP calling.

A telephone system that resides in the cloud rather than in your office. Users access the system through a standard IP handset or a softphone – a screen-based virtual phone with headset. Calls are made/received over a broadband connection to the Gamma network. From there they are routed to PSTN fixed and mobile devices.

With only a minimal capital outlay required, Horizon is suitable for any size of business looking to improve its productivity and image.

A site survey is a useful exercise as it enables superfluous services and hardware to be identified, highlighted and considered during the decision-making process. As a cloud-based telephony platform, Horizon lets you dispense with a physical PBX and the associated cost of maintenance and it requires only the simple installation of on-site handsets. For larger, multi-sited customers the savings made will clearly be multiplied. Of course, as well as working seamlessly with Gamma’s SIP, Ethernet and Broadband products, Horizon can interface with legacy connections too, making it the totally flexible solution.

Horizon is the perfect platform for organisations that require a professional and simple-to-use interface with the outside world. Schools, public sector organisations, major venue and event operators; each has its own challenges in terms of maintaining staffing levels, training and cost, with the result that often it’s the first line of communications that suffers. Horizon is simple to set up and use and it lets you present a simple, flexible and, above all, totally professional image.

Call quality, as with any communications system, is clearly dependent on the underlying access available. With our Ethernet and Broadband products delivering the service to your locations, you can be assured of great voice quality, underpinned by some of the most stringent SLAs in the business.

Listening to your customers can offer a valuable insight into your organisation: maximising customer service, helping with staff training, and ensuring peace of mind when it comes to due diligence.

Gamma’s intuitive and secure call recording solution is deeply integrated with Horizon’s cloud platform, giving direct control to you over both your telephony and your call recording solution.

  • One intuitive software service – recordings can be accessed, downloaded and noted on from one web login.
  • Record the speaker, not the number – Advanced Call Recording will record your users, whether they are speaking on a mobile, office phone, or soft client.
  • Order and use on a native cloud platform – you’ll have a scalable investment, with a clear, usage based payment structure.
