We’ve been building phone systems for UK businesses since October 2007, and we became a 3CX partner back in 2009 — long before it was fashionable. The reason was simple: it was the first phone system that treated businesses like adults. One licence for the whole system instead of a charge for every person. Software that runs where you want it. No lock-in to one manufacturer’s handsets.
Seventeen years on, that bet has become our specialism. We’re now a Titanium (the highest tier) partner, and we’ve taken hundreds of UK businesses onto the platform: designed properly, migrated without drama, and looked after by real people who answer the phone. A 3CX phone system is a brilliant thing. A 3CX phone system with a team behind it is peace of mind.
If you’re weighing it up, don’t wrestle the forum threads alone. Bring us your questions — the consultation is free, we listen first, and you’ll leave knowing exactly what your system should look like, whether you buy it from us or not.

3CX is a software-based business phone system (a PBX, built on the open SIP standard) used to run calls, video meetings, live chat, WhatsApp and SMS in one platform. It works in the cloud, on-premise on your own hardware, or a mix of both — and it’s licensed by simultaneous calls rather than per user, which is why it usually costs less as you grow. We use it because it lets businesses own their phone system rather than rent it.
The software is excellent — that’s rarely where problems come from. Real-world 3CX experiences are decided by how it’s deployed and looked after: due diligence on the network, a properly sized licence, supported trunks, and a partner who answers. Run well, it’s outstanding value. Run as a sideline, it disappoints — which is why making it work beautifully is Zen Systems’ whole focus.
It usually isn’t — for the 10-plus-person businesses 3CX now focuses on, independent comparisons typically put total cost 30–50% below per-user platforms. Quotes vary wildly, though, because the licence is only part of the picture: a flat annual licence sized by simultaneous calls, with hosting, SIP trunks, handsets and support added separately — often by different suppliers. Very small businesses can find it expensive at face value; from around ten people it usually flips firmly the other way. Zen Systems quotes one simple price with everything included, so there are no surprises.
Yes — 3CX’s free small-business tier (3CX SMB) is genuinely free for up to 10 users, indefinitely, with hosting included; you’ll still need a SIP trunk for your number and calls. There’s also a tiny free self-hosted edition (4 simultaneous calls). Fine ways for a small team to start — but growing businesses outgrow them quickly: queues, deeper integrations, intelligence and support live in the paid editions, which is where we come in.
That choice is one of 3CX’s real advantages — there are three routes. Most of our customers choose our private cloud, hosted in Equinix London with a 99.99% uptime SLA, so there’s no server to own or patch. 3CX also offers its own hosted option on public cloud, and you can self-host — on-premise or in your own cloud (Amazon, DigitalOcean, Azure or Google). It’s your call, and we’ll advise honestly.
Yealink, Fanvil and Snom are 3CX’s preferred handset makers — tested against every release, auto-provisioning in minutes. Others, like Grandstream, Polycom and Gigaset, are supported with limitations. Or skip handsets entirely and use the apps on laptop and mobile.
Yes — it’s the line that connects your system to the phone network. We provide and manage the trunks as part of the service, so calls are one supplier’s responsibility: ours.
Yes — it’s one of the most common ways businesses join us. Whether you’re hosted by 3CX directly or with another 3CX partner, the takeover is simple: your licence and configuration transfer to our care with no downtime, and anything provider-specific — like number porting — we map out together in your free 3CX health check.
There are three paid editions. Basic covers dependable everyday calling — desk phones, the apps, auto attendant, voicemail. Pro adds the customer-facing layer: call queues, recording, queue reporting, CRM and Microsoft 365/Google integration, and multi-site working. AI adds the intelligence — the AI receptionist, transcription, sentiment and insights — plus resilience extras like built-in failover. We right-size the edition in your quote, and you can step up as you grow.
Honest answer: it depends who you’ve got. If your IT team is comfortable running a phone system — patching, trunks, backups, upgrades — self-managing works well, and we’ll happily sell you the licence at a fair price and stay nearby. Most businesses choose our fully managed service instead: licence, hosting, SIP trunks and support in one price, with real people accountable for all of it. It’s the difference between owning a system and having to carry it.

3CX Phone System is a brilliant thing.
3CX with a team behind it is Peace of Mind.
Both are free and no-obligation — we listen first, no pressure.
