3CX is a software-based phone system that replaces a traditional hardware PBX with a platform you can host in the cloud or run on your own server, connecting to your existing VoIP lines or SIP trunks rather than requiring a fresh phone network from scratch. It supports desktop and mobile apps, browser-based calling, video conferencing, call queues and voicemail-to-email, all managed from a single web console — which is exactly why so many UK businesses moving away from a legacy phone system land on 3CX as the platform, then need someone to actually deploy and look after it properly.
Getting the licensing right is where most self-managed deployments go wrong. 3CX licenses by simultaneous call count rather than by user, which means a 20-person team that rarely has more than six people on the phone at once needs a very different tier to a call centre where nearly everyone is on a call simultaneously. We size this against your actual calling patterns rather than your headcount, so you're not overpaying for concurrency you'll never use or under-provisioned for your busiest hour.
Integration is the other place a 3CX phone system either earns its keep or becomes another disconnected tool. We connect it to your existing SIP trunks or VoIP lines, port your existing numbers where possible, and configure the desktop and mobile apps so staff working from the office, from home or on the road all have the same extension and call history. Where it's useful, we also configure CRM click-to-dial and call logging integrations, so the phone system feeds into how your team already works rather than sitting apart from it.
A self-hosted PBX exposed to the internet is also a genuine security consideration, not a footnote — misconfigured 3CX systems are a known target for toll fraud and unauthorised call routing. We configure firewall rules, session border controller settings and access restrictions properly at deployment, then keep the system patched and monitored on an ongoing basis, rather than leaving a phone system installed once and never revisited.
Migrating to 3CX from an existing system is also something worth planning rather than rushing. If you're moving off a legacy hardware PBX, we map every current extension, hunt group and voicemail box before cutover, so nothing quietly disappears on go-live day. If you're moving from a different hosted VoIP provider, we check contract notice periods and number porting timescales in advance, since porting can take longer than the 3CX deployment itself if it isn't started early. Either way, we aim for a cutover where staff notice a better phone system, not a disruptive one.
3CX has become one of the most widely deployed PBX platforms among UK SMEs because it separates the phone system from any single hardware vendor or handset — you can run it in the cloud, on a Windows or Linux server on-site, or as a managed private cloud instance, and connect whichever SIP trunk provider gives you the best rates and coverage. That flexibility matters for a business that's grown through mergers, office moves or a shift to hybrid working, where a rigid, hardware-locked phone system quickly becomes the thing holding everything else back.
Licensing by simultaneous calls rather than per seat means a growing headcount doesn't automatically mean a growing phone bill, provided the tier is sized against real usage rather than guessed at.
Desktop, mobile and browser-based softphone apps all share the same extension and call history, so staff working from home or on the road are as reachable as someone sitting at a desk in the office.
3CX connects to standard SIP trunks and common CRM platforms, so you're not forced to replace your existing number range or your customer records system to make the phone system work.
The 3CX deployment and support work most businesses would rather not handle themselves.
We size your 3CX licence tier against actual concurrent-call data, not headcount or guesswork, so you pay for the capacity your business genuinely needs.
Firewall rules, access restrictions and session settings are configured properly at deployment, then kept patched and monitored, rather than left as a one-off install.

24/7 monitoring, patching and support for your 3CX system, backed by our 99% SLA guarantee.
We size your 3CX licence tier against actual concurrent-call data, not headcount, so you're never paying for capacity you don't use.
Deployment, licensing and ongoing patching are handled by the same team, so there's no gap between the people who set the system up and the people who support it when something needs attention months later.
Deployment includes number porting, SIP trunk configuration and app setup for every user, whether they're in the office, at home or on the road.
Security is built in from day one — firewall rules, access restrictions and session settings configured properly, then kept patched and monitored rather than left as a one-off install.
Your 3CX system sits alongside our wider connectivity, network administration and managed IT support services, so if a call quality issue turns out to be a network problem rather than the phone system itself, the same team can fix it.
We're upfront about whether cloud-hosted or on-premise 3CX suits your business better, and we'll review your licence tier again as your team and call volumes change, rather than leaving you locked into a spec that no longer fits.
Pricing depends on licence tier, hosting model and number of SIP trunks. Every quote is tailored — get in touch for a free assessment.

A phone system is core infrastructure, not an afterthought. Here's what sets us apart.
We size your 3CX tier against actual concurrent-call data, not headcount, so you never overpay for capacity you don't need.
Firewall rules, access restrictions and session settings are configured properly at deployment, then kept patched and reviewed.
A written service level commitment on your phone system, not just a marketing promise.
We monitor call quality and SIP trunk performance, catching degradation before it becomes a dropped call.
VoIP, connectivity, cloud email and managed IT support sit under the same roof, so problems don't get passed between suppliers.
We'll recommend cloud-hosted or on-premise 3CX based on what actually suits your business, not the option easiest for us to sell.
We're upfront about licence cost, SIP trunk cost and our management fee, so quotes are easy to compare.
Adding users, extensions or a new office is a conversation, not a full renegotiation of your licence.
Contract terms are explained clearly before you sign, so there's nothing awkward buried in the small print later.
A traditional hardware PBX ties you to physical handsets and a specific vendor, with upgrades meaning a costly hardware refresh rather than a software update. A fully hosted VoIP provider removes the hardware but often locks you into their platform, their handsets and their pricing, with limited control over configuration. 3CX sits between the two: it's software you can run in the cloud or on your own server, connect to whichever SIP trunk provider suits you, and configure without being tied to a single vendor's roadmap. For most UK SMEs replacing an ageing PBX or moving away from a rigid hosted provider, that flexibility — combined with licensing based on concurrent calls rather than per seat — is usually what makes 3CX the more cost-effective long-term choice, provided it's deployed and secured properly. It's also worth factoring in the cost of getting it wrong: an incorrectly licensed system either strands you mid-call during your busiest hour, or quietly overcharges you every month for capacity nobody's using, and both are easy to avoid with a proper assessment upfront rather than a guess at sign-up.
3CX has grown into one of the most widely deployed software PBX platforms among UK SMEs, largely because it decouples the phone system from any single handset vendor or SIP trunk provider. Businesses moving away from an ageing hardware PBX, or away from a hosted VoIP provider that's become too rigid or expensive, frequently land on 3CX as the platform of choice.
What to look for in a provider: a licence tier properly sized against your actual concurrent-call data, genuine security configuration rather than a default install left exposed to the internet, and ongoing monitoring so faults and patching aren't left to chance.
Sectors we support: professional services firms needing CRM-integrated calling, retailers and hospitality groups with multiple sites, and any hybrid team that needs staff reachable on the same extension whether they're in the office or at home.
How we deliver it: Our deployment and support is remote-first for businesses across the UK, with on-site coordination for physical handset installs when genuinely needed.

Got questions about the 3CX phone system? We've answered the most common ones below.
3CX is a software-based PBX that can be hosted in the cloud or run on your own server, connecting to standard SIP trunks and supporting desktop, mobile and browser-based calling apps rather than requiring proprietary hardware handsets.
Pricing depends on the licence tier, hosting model and number of SIP trunks required. We'll assess your call volume and provide a tailored, transparent quote rather than a generic per-user price.
Cloud-hosted suits most businesses that don't want to manage server hardware; on-premise suits those with specific compliance or infrastructure requirements. We'll recommend based on your setup rather than a default answer.
No — most staff can use the desktop, mobile or browser-based softphone apps without any physical handset, though we can also configure compatible desk phones where they're genuinely preferred.
In almost all cases, yes. We handle the number porting process as part of deployment, so your existing numbers transfer across to the new system.
A straightforward single-site deployment typically takes one to two weeks including number porting; multi-site or CRM-integrated deployments can take longer, which we'll confirm at assessment stage.
Not without proper configuration. A misconfigured PBX exposed to the internet is a known target for toll fraud, which is why we configure firewall rules and access restrictions properly at deployment and keep the system patched afterwards.
Yes — the mobile and desktop apps give remote staff the same extension, voicemail and call history as someone working from the office, so they're just as reachable wherever they're working.
