3CX Business Phone System

TechNext IT deploys and manages 3CX business phone systems. VoIP, softphones, call routing, and Microsoft Teams integration set up and supported.

Your phone system should not be the reason you miss a call from a customer.

Outdated phone systems, dropped calls, and confusing voicemail setups cost businesses more than they realise. TechNext IT deploys 3CX to give businesses a modern, reliable phone system that works across desk phones, mobile apps, and desktops, with none of the limitations of traditional landlines.

What is 3CX?

3CX is a software-based business phone system that runs over your internet connection instead of traditional phone lines. It supports desk phones, mobile apps, desktop softphones, and web-based calling, all managed from a single platform. 3CX includes features like call routing, auto-attendants, voicemail-to-email, call recording, and live chat, built in at no extra per-user cost.

Unlike traditional PBX systems that require expensive hardware and phone lines, 3CX runs on standard internet connections and can be hosted in the cloud or on-premise depending on your requirements.

Who 3CX is for

Any business that takes phone calls and wants a professional, flexible system without paying per-user fees to a telco. That includes reception-heavy businesses like medical practices, legal offices, and real estate agencies, as well as trades businesses that need calls forwarded to mobile, and multi-site organisations that want a single phone system across all locations.

3CX is also a strong option for businesses replacing an aging PBX or moving away from a telco-managed phone system where they have limited control and high monthly costs.

How we use 3CX

We design, deploy, and manage 3CX phone systems as a complete communications solution. Every system is configured around how your business actually handles calls, not a generic template.

Call recording for compliance, training, or quality assurance
Microsoft Teams integration for businesses that want calling capability inside Teams
Multi-site configuration so all your locations run on one phone system with internal extensions

Why businesses trust TechNext IT with 3CX

A phone system is business-critical infrastructure. When it stops working, your customers cannot reach you and your team cannot do their job. We treat it with the same seriousness as your network and security.

We design the system around your business. Call flows, ring groups, auto-attendants, and after-hours handling are all configured to match how your team actually works.
We handle the full migration. Number porting, handset setup, user training, and cutover are all managed by our team so the switch is seamless.
We support it ongoing. Adding users, changing call flows, troubleshooting audio issues, and managing handsets are all part of the service.
We pair it with the right hardware. 3CX works best with quality handsets like Yealink. We specify and supply the right phones for every role in your business.

Projects we deliver with 3CX

Phone system projects are usually triggered by a failing legacy PBX, frustration with a telco-managed service, or a business that has simply outgrown its current setup.

Full phone system replacement — Removing an old PBX or telco-managed system and deploying 3CX with new handsets, number porting, and staff training
Multi-site phone system — Connecting multiple offices under a single 3CX deployment with shared extensions, call transfers, and centralised management
Teams calling integration — Adding 3CX as the calling engine inside Microsoft Teams so staff can make and receive external calls without leaving Teams
Remote worker phone setup — Deploying 3CX softphones and mobile apps so remote staff have a full business phone on their laptop or mobile, with the same number and features as the office

Common questions we get from businesses about 3CX. If yours isn't answered here, get in touch and we'll help.

Can 3CX work with Microsoft Teams?

Yes. 3CX integrates with Microsoft Teams so your team can make and receive external calls directly inside Teams. This is a popular option for businesses that already use Teams for internal communication and want to consolidate everything into one platform.

What happens to our phones if the internet goes down?

If your internet connection drops, desk phones and softphones will lose connectivity. To protect against this, we recommend a failover internet connection and can configure 3CX to route calls to mobile phones automatically during an outage so your business never misses a call.

Can we keep our existing phone numbers?

Yes. We handle number porting from your current provider as part of every 3CX deployment. Your business keeps its existing numbers and your customers will not notice any change.

Do we need special phones for 3CX?

3CX works with standard SIP desk phones, and we recommend Yealink handsets for the best compatibility and call quality. It also supports softphone apps on desktops and mobile devices, so not every staff member needs a physical handset.

What is the difference between 3CX and a traditional phone system?

Traditional phone systems run on dedicated phone lines and physical PBX hardware. 3CX runs over your internet connection and is managed through software. That means lower costs, more flexibility, and features like mobile apps, softphones, and Microsoft Teams integration that traditional systems cannot offer.
