Evonex vs Gamma Horizon

Two hosted phone platforms, both with nothing on your premises. The choice comes down to two things: whether your business lives in Microsoft Teams, and whether you need serious call reporting.

They are more alike than the sales material suggests

Evonex and Gamma Horizon are both hosted telephony platforms. Neither puts a system in your comms cupboard, both survive a site going offline because the platform is not in your building, both handle the call routing, auto attendants, queues and voicemail that any business needs, and both replace the lines that stop working in January 2027. If you are choosing between them expecting one to be fundamentally more capable than the other, that is not the distinction.

The real difference is where each one is strongest. Evonex is the platform SCG runs itself, and its notable feature is native Microsoft Teams integration — if your people already spend the day in Teams, calls happen there rather than in a second application they have to remember to open. Horizon’s strength is reporting: through Akixi it does the kind of call analytics that a contact-centre style operation actually needs, rather than the basic call logs most platforms offer.

So the honest way to choose is to ask which of those two things you would miss. A professional services firm running on Teams will get more from Evonex. A business with a phone room, wallboards and a supervisor who needs to see queue performance in real time will get more from Horizon. A business that needs neither can pick on price and support, and will be fine either way.

Where they differ

Microsoft Teams

Evonex integrates natively, so calls live in Teams. Horizon works alongside Teams rather than inside it.

Call reporting

Horizon, through Akixi, does genuine contact-centre analytics. Evonex covers DDI reporting and call analytics for normal business needs.

Continuity

Both survive your building going offline. Horizon carries built-in disaster recovery as a named feature.

Who runs the platform

Evonex is SCG’s own, so platform issues stay in house. Horizon is Gamma’s, a large and long-established UK provider.

Delivery

Horizon is commonly delivered over dedicated fibre or managed Ethernet with quality of service applied to voice traffic.

Upgrades

Neither needs hardware replacing. Horizon includes free platform upgrades; there is no version to fall behind on either.

Who we work with

We are independent of any single network or vendor, so the recommendation follows the requirement.

Telephony platforms

Hosted, on-premise or Microsoft Teams — the right answer depends on the building, not on what we prefer to sell.

Which one to pick

Your team already works in Microsoft Teams all day — Evonex, for the native integration
You run a phone room, queues and supervisors who need live stats — Horizon, for Akixi reporting
You want the platform and the support to sit with the same company — Evonex is SCG’s own
You want a large independent UK platform provider behind it — Horizon is Gamma’s
You need neither Teams nor deep reporting — either will do the job; choose on price and support
You are not sure — say what your people actually do all day and we will tell you which fits

Evonex vs Gamma Horizon — Common Questions

Is Evonex or Horizon better?

Neither, in the abstract. They are both hosted platforms with no on-site hardware and both do what most businesses need. Evonex is stronger if your people work in Microsoft Teams; Horizon is stronger if you need genuine call-centre reporting through Akixi. If you need neither, both are fine and the decision comes down to price and support.

Which one integrates with Microsoft Teams?

Evonex has native Teams integration, so calls happen inside the application your staff already have open rather than in a separate softphone. Horizon works alongside Teams rather than inside it. If Teams is already where your business lives, that difference is usually the deciding one.

Which is better for call reporting?

Horizon, through Akixi — it does the kind of live queue statistics, wallboards and historical analysis that a contact-centre style operation depends on. Evonex covers DDI reporting and call analytics, which is enough for most businesses but not for a supervisor who needs to watch a queue in real time.

Can I move between them later?

Yes, and your numbers come with you either way, so nothing on your signage or stationery changes. It is not a decision you are locked into for a decade the way an on-premise system used to be — which is worth remembering if you are agonising over the choice rather than getting off the copper network before 2027.

Do both work if our office loses power or internet?

Yes, because neither platform is in your building. Calls carry on being handled and can route to mobiles or another site automatically. That is the main practical advantage both have over an on-premise system, which stops answering the moment the building does.

Who supports the platform if something breaks?

SCG either way — you deal with your local director and the group support desk rather than with a platform vendor. The difference is that Evonex is SCG’s own platform, so a platform-level issue is handled in house, while Horizon is Gamma’s and some fixes ultimately sit with them.

Not sure which platform suits you?

It is a short conversation. How your people work, whether Teams is already central, and whether anyone needs to watch a queue in real time — those three answers usually decide it, and we are happy to say when either would be fine.
