The Gamma Horizon Portal – the Game Changer

One of the massive advantages that Gamma Horizon has over it’s competitors and other premises based phone systems is the Gamma Horizon portal.

Watch the video below for an insight into how the portal let’s you have instant and full control over your organisation’s business communications – we won’t explain it in detail but just watch the video as it will sell itself. It’s a WIN/WIN.

Oh and you don’t have to worry about system and portal set up and training – we will do everything for you before your system goes live – then you can take control or have us deal with any moves and changes for you.

What are the alternatives to a hosted system like Gamma Horizon ?

Well you can still choose a premises-based phone system – we provide AVAYA and Mitel systems – see below.

However, we would recommend you install a SIP trunk rather than a traditional ISDN connection


The IP Office is one of the world’s most successful telecoms stories. Originally introduced in 1999, it has evolved and adapted into a huge phenomenon.

In our opinion this is due to is appealing to a varied number of businesses of all sizes, it’s strong feature set and it’s price.

See our dedicated page on AVAYA IP Office for more detail.

IP Office is a hybrid system which means it can use a multitude of different technologies including lines that are ISDN30, ISDN2e, SIP or analogue. Plus extensions can be digital, analogue, IP or SIP. So it is very versatile.

Mitel MiVoice Office 250

Much like the IP Office, this system has a wide ranging appeal to all sorts and sizes of organisation.

For a certain type of requirement though, the MiVoice Office definitely pips IP Office to the post.

Examples would be organisations running Contact Centres (Call Centres) or needing integration with a software package to allow screen popping and clicking and dialing.

Like IP Office, it is a hybrid meaning that it can use lines that are ISDN30, ISDN2e, SIP or analogue. Plus extensions can be digital, analogue, IP or SIP. So it is very versatile.

Gamma Horizon Pricing

Ok so you want to know the Gamma Horizon Pricing….

There is a standard price that we apply but for most scenarios we put together bespoke pricing for every customer. Why? Because every customer is different.

Typical Gamma Horizon pricing is made up of the following elements:

1 – Premium Subscription – this is the price per user and this is normally fixed for the length of your agreement with us. You can easily add or reduce user numbers dynamically subject to your agreement – this is great for organisations who want flexibility.

2 – Handsets – these are normally provided free of charge on a 3 year agreement

3 – Connectivity – as part of your project, we would normally be installing special internet connections that guarantee voice quality and often these can be used for normal internet access to although we can deliver Gamma Horizon across your existing connection if we deem it good enough.

4 – Extras – a lot of the Gamma Horizon features are included as standard but there are some extras such as smartphone apps. PC soft phones, call recording, contact centre solutions and CRM integration (click to dial and screen popping)

5 – Networking – often we will be installing and supporting a new POE switch for your phones to connect to – this may also include a UPS and also a router/firewall if appropriate

6 – Peripherals – things like headsets and conferencing solutions are extra

7 – Professional Services – this is our time and expertise to manage your projects and install, configure your system and provide training so all your staff  get to make the most out of the Gamma Horizon system

8 – Support – this is provided as part of the price

Note that all of the above can be rolled up into a single monthly cost if you prefer.

Please contact us so we can discuss your specific scenario and provide advice and pricing.

 Gamma Horizon Reviews

Here are just a few comments from our customers that use Gamma Horizon.

“What an improvement – we are now agile, lean and mean and we can work from anywhere – and we are saving money and have better internet connectivity –  a no brainer!”

“We recently relocated our company and tecwork installed our telecoms and internet system.  The transition was incredibly smooth without any interruption to our business.  Nick and his team kept us informed of the full process and provided full training and support.

The Gamma Horizon system has provided us with the solution we needed and transformed our operations.  It allows us to take calls from any location, either through divert to mobiles or when working from home, through our laptops.  The internet speed is incredibly fast and reliable and our business is more agile.  Our monthly bills are lower, with no extra costs for new handsets and continued technical support.”
