Gamma Horizon Hosted Phone system Review

Gamma Horizon Hosted Phone System [PRODUCT REVIEW]

So, for the last 10 years the hosted phone system has been growing in hype and popularity, the Gamma Horizon Hosted phone system has now become one of the leading systems in the UK marketplace.

Gamma have been at the forefront of VoIP for many years, including their industry leading SIP trunking offering.

The Horizon phone system is built on one of the world’s leading hosted platforms in Broadsoft and brings 2 of the main players in VoIP together to create what professes to be a very powerful solution for businesses in the UK.

With so much excitement within the Telecoms industry we thought it was time to put it through its paces against more traditional PBX solutions available on the UK market.

History of Gamma Horizon

The Horizon hosted phone system has been available in the UK since 2011. There were previous iterations of the hosted PBX from Gamma in the forms of the Feature plus and Communicator systems.

The horizon system has been sold through Gamma’s network of channel partners and resellers, of which Comms Consult are one, to gain a very strong foothold in the UK business telecommunication market.

Gamma is a UK carrier and has built out its own network for voice, data and mobile services. They only work with businesses in the UK and have placed huge emphasis on the availability, reliability and quality of the network. Great if you are a business needing to provide a good level of customer service, and let’s be honest if you’re not you won’t be in business long!

How easy is it to install?

With hosted phone systems, part of the attraction is the speed of deployment. With Gamma Horizon it becomes even simpler than some of the systems we’ve used in the past.

The engineers back in the office (well we don’t even need ‘engineers’ it’s that simple to set-up but don’t tell them) take the initial client specification and project specification documents and configure the overall system preferences. For example, the number of extensions needed on the phone system, therefore the number of voicemail boxes needed, any specific routing options which get specified in the pre-installation meeting.

That’s the phone system bit done, then the MAC address of each phone is programmed into the extension panel in the online portal. The phone can then be plugged into the internet within the office or can just be left in the box to be shipped out to the client site.

The auto-configuration means that we can send out phones through the post, not that we do, which can be unboxed by the client, plugged into an internet connection and boom, you have your phone system up and running.

We do, however, specify that our clients use the Gamma Horizon PBX with the dedicated internet connection that Gamma provide. This way we have one point of support if anything should happen and we need to diagnose what the problem is. If we stick with Gamma throughout as much of the technology set-up as we can then it is easier to fix.

How reliable is the connection?

As per the above paragraph, we make sure that we only install the system within premises using the Gamma dedicated internet connection.

When using this there are certain guarantees for service uptime. But we’ve only had one incident where the system stopped working in the last 4 years and this was overnight for about 30 minutes.

Is the system scalable?

A hosted phone system is scalable by nature. It is built to work by making the phone connections via the internet.

Cost of ownership

The package we have negotiated with Gamma means we can offer most businesses (depending on number of extensions) a free phone, free installation, free unlimited calls to all mobiles & landlines and free support starting from £12.50 per month per handset!

I mean how much better could a cost of ownership be? No capital expenditure and one fixed monthly fee for everything.

Main features of the system

There have been additional features added to the horizon system over the years but fundamentally it is a VoIP hosted phone system that can make, take and transfer phone calls. But with it being hosted it can do this to handsets which are spread across the world.

The Gamma horizon hosted phone system gets a 5 star from us here at Comms Consult. We use it ourselves and recommend it to 75% of our prospective customers. The main reasons are the price factor, the feature set out of the box and the pure ease of use.

They have produced a phone system in the horizon platform which provides the end user with everything they want from a phone system but in a monthly, easy to manage price. It removes any of the normal associated costs of a more traditional ‘in the data rack’ type phone system.
