Gamma vs Telexico, honestly.
Gamma Horizon is an established, reliable UK hosted phone platform — but it's sold and supported through resellers, so your experience depends on the partner in the middle. Telexico engineers and supports your system directly. Here's a fair comparison, including when Gamma is the better choice.
- 📞 Gamma Horizon phone system
- 🤝 Reseller you struggle to reach
- 🟦 Teams calling via a partner
- ☁️ Hosted VoIP / Cloud PBX
- 📡 Adding business broadband
- 🤖 Adding an AI Receptionist
- 📹 WiFi & CCTV
- 🔄 Full multi-service consolidation
Both are hosted phone systems on solid networks.
Gamma and Telexico both deliver cloud / hosted VoIP phone systems — desk phones and apps, call routing, queues, voicemail-to-email — over the internet, and both are valid answers to the 2027 PSTN switch-off. Gamma Horizon is built on a well-proven platform, and Gamma operates its own UK network, which makes it reliable.
Here's the key thing about Gamma, though: Gamma sells almost entirely through resellers and partners. You don't usually buy from Gamma directly — you buy Gamma Horizon from a partner who quotes it, sets it up and supports it. Gamma the network is excellent; the variable is whichever reseller sits in the middle.
So the comparison isn't really about the platform — it's about who delivers and supports it. With Telexico there's no reseller: the team that quotes your system is the team that engineers and supports it.
Six things that aren't the same.
Both are capable hosted systems. The difference is who delivers it, who supports it, and how transparent the deal is.
Delivery model
Gamma: Sold and delivered through third-party resellers. Quality, price and support all depend on which partner you happen to use — and they vary a lot.
Telexico: No reseller. We design, install, configure and support your system directly, so there's no middle layer between you and the people who run it.
Support ownership
Gamma: Partner-led. When something breaks, your reseller may need to escalate to Gamma, which can bounce a problem between two companies.
Telexico: One named UK contact and direct engineer access. The person who set you up owns the fix end-to-end.
Pricing transparency
Gamma: Partner-quoted and not publicly listed — typically ~£10–20/user basic, ~£20–30 advanced, plus a setup fee, but it depends entirely on the reseller's margin.
Telexico: Transparent pricing from £15/user/month all-in, quoted directly by us.
Contract terms
Gamma: Your contract is with the reseller; terms, notice periods and price reviews vary by partner.
Telexico: Clear, reasonable terms stated upfront, no silent auto-renewal, exit explained before you sign.
Where support sits
Gamma: Wherever your chosen partner happens to be — could be anywhere in the UK.
Telexico: Wolverhampton-based engineers who can attend on-site locally.
Beyond phones
Gamma: Gamma is telephony and connectivity, delivered via the partner.
Telexico: Full stack under one roof — phones, broadband, leased lines, WiFi, CCTV, AI Receptionist — one bill, one team.

Gamma's platform is genuinely solid and its network reliable — the variable is the reseller in the middle. With Telexico there's no reseller: the team that quotes it engineers and supports it, locally.
What it might cost — 5 vs 10 users.
Illustrative monthly figures to show the shape of the difference, not a quote. Confirm current prices with each provider — competitor pricing changes and some isn't publicly listed. Telexico figures are typical all-in ranges; your quote depends on users, features and term.
| Scenario | Competitor (illustrative) | Telexico (illustrative, all-in) |
|---|---|---|
| 5 users | ~£75–100/month via a partner, plus setup; depends on the reseller's margin. | from £90/month all-in, supported directly by us |
| 10 users | ~£150–200/month partner-quoted; advanced tiers more. | from £170/month all-in, no reseller in the middle |
Gamma Horizon is partner-priced, so the total varies by reseller. The Telexico figure is quoted directly and all-in.
When Gamma is genuinely the right answer.
Gamma Horizon is a strong platform. Here's when it's genuinely the right answer.
You already have a great Gamma partner. If your reseller is responsive, fairly priced and knows your business, there may be no reason to change — Gamma's platform is reliable and well-supported when the partner is good.
You specifically want the Gamma Horizon / Collaborate ecosystem. If you've standardised on Gamma's feature set and Teams integration through a managed partner, it's a capable, governance-friendly choice.
You're a Microsoft-aligned organisation wanting partner-managed delivery. Gamma is commonly used in Teams environments with a partner handling admin and governance.
If you'd rather deal directly with the team that installs and supports it — locally, with no reseller in the middle and transparent pricing — that's exactly how Telexico works.
Moving from Gamma to Telexico.
We project-manage the whole switch. Here's exactly how the four things people worry about are handled.
Number porting
We port your existing numbers across to Telexico — they stay exactly the same. We submit the porting request, manage the dates, and keep your Gamma service live until the port completes.
Downtime
None, done properly. We build and test your new system alongside your existing Gamma service and only cut over once it's proven. Most switches complete in 7–14 working days.
Existing handsets
Gamma Horizon typically uses standard SIP handsets (Yealink, Poly) which we can usually re-provision to Telexico — we'll confirm your models.
Contract exit
Your Gamma contract is with the reseller; terms and notice vary, so check your partner agreement. We check your end date first and tell you honestly whether to move now or wait — we won't push an exit that costs more than it saves.

Frequently asked questions
Is Telexico cheaper than Gamma?
It depends on the reseller, since Gamma Horizon is partner-quoted rather than publicly listed. Telexico's pricing is transparent from £15/user/month all-in. The bigger difference is structural: with Gamma there's a reseller setting the price and margin; with Telexico you deal directly with the team that builds and supports your system. Send us your Gamma quote and we'll compare it properly.
What does it mean that Gamma is a 'reseller model'?
Gamma operates its own UK network but sells Horizon almost entirely through partners. You buy from, are quoted by, and are supported by a reseller — not Gamma directly. The platform is consistent, but your price, contract and support experience depend heavily on which partner you use.
Can Telexico replace Gamma Horizon?
Yes. We'd review your current setup and partner contract first, then port your numbers and set up your system directly. Most Horizon deployments use standard SIP handsets that we can re-provision, so a switch is usually straightforward.
Is Gamma a bad choice?
No — Gamma's network and platform are reliable and well regarded. The thing to weigh is the reseller in the middle: a good partner makes Gamma excellent, a poor one makes it frustrating. Telexico removes that middle layer by supporting you directly.
Will I keep my phone numbers?
Yes. We port your existing numbers across and keep your current service live until the new one is proven, so there's no downtime.
Is Telexico local to Wolverhampton?
Yes — our office is at 64 Chapel Ash, Wolverhampton WV3 0TT, with engineers across the city daily. With Gamma, where your support sits depends on which partner you use.
