Excellent VoIP System for Our Business Needs
What do you like best about the product?
3CX has been easy to use and works great for our daily communication. Setup took a bit of learning, but support and guides helped a lot. We use it every day—it has all the features we need, and it connects well with our other tools. Overall, it’s been a reliable and cost-effective solution.
What do you dislike about the product?
There’s a bit of a learning curve at first, especially with the admin settings. Some advanced features can be tricky to configure without support. Also, occasional updates can cause minor issues that need troubleshooting.
What problems is the product solving and how is that benefiting you?
3CX has solved our communication issues by giving us a reliable phone system that works in the office and remotely. It’s helped us stay connected as a team, manage calls more efficiently, and save money compared to traditional phone systems.
Adaptable, Configurable, Dependable
What do you like best about the product?
3CX has been installed for about 5 years at my company - it was easy to install, it was easy to set up, and it has been easy to customise for our requirements. I've never once been unable to solve a problem using 3CX. We have specific requirements for out of hours contact, and have implemented a rota system for out-of-hours support using just 3CX and a bit of logic.
Despite the system being 5 years old, it has been regularly upgraded to the latest release - a process that is easy and dependable.

What do you dislike about the product?
3CX can sometimes be a bit picky about how certain SIP devices connect, but their support channels and the 3CX community have been very helpful in remediating these issues.
What problems is the product solving and how is that benefiting you?
3CX provides us with a reliable and scalable phone system: it does call queuing, ringback and sends voicemails directly to our Teams channels. We have written custom phone templates for high-security areas, and have had great success with the mobile app for extending our PBXs reach for our users.
Does everything we need and more.
What do you like best about the product?
After evaluating many options 3CX proved to offer most bang for the buck.
Particularly liked that you pay for simultaneous calls as opposed to per device which really suits the way our business works.
A good quality phone system says a lot about a company and 3CX delivers. It was easy to integrate with our company database to do advanced features like routing calls to customers account managers without having to use DDIs.

Everything can be found all in one place. I don't have to go searching around multiple sites or applications to find what I'm looking for.
What do you dislike about the product?
Reporting is still lacking a bit. For instance - on my wallboard I can see my average wait time but cannot view this number in any reports

Our call queues help us manage our help desk be more efficient. We use the live chat feature on our website and it allowed us to eliminate another 3rd party for this. We use the video conferencing feature to host webinars with our clients.
Transformed Our Telephony Across 20 Schools – Reliable, Cost-Effective, and Cloud-Ready
What do you like best about the product?
3CX has completely transformed the way we handle communication across our Multi Academy Trust. We're running our own self-hosted version using a cloud based datacentre host, linking 20 school locations—three secondaries and 17 primaries—all under one centralised system.
Every staff member has their own extension, which has been a game-changer for staying connected, whether it's during field trips or on days when adverse weather keeps people working from home.
It really came into its own during lockdown. While many were scrambling to patch together remote communication, we were able to switch to remote operations seamlessly. The flexibility it provides is outstanding.
From a financial perspective, it’s been a massive win. Our entire setup—including all SIP lines—costs us less than £10k a year. To put that into context, each of our secondary schools used to pay that much *individually* per year. Now, we have a unified, internal system that’s saving our Multi Academy Trust a significant amount annually while giving us more control and consistency.
Teachers and support staff genuinely love the platform. Features like click-to-call have been an unexpected highlight—especially when it comes to reaching out to parents through our MIS. It’s intuitive, efficient, and fits perfectly into our cloud-first approach.
I’m a huge fan of 3CX and can't see us moving away from it anytime soon. It’s not just a telephony solution; it’s part of our digital backbone now.

What do you dislike about the product?
If I had one wish for future development, it would be deeper integration with Microsoft 365. For example, being able to automatically assign extension numbers based on group membership—like giving everyone in a specific M365 group an extension starting with "32XX"—would streamline onboarding and user management even further. It’s a small ask, but it would take an already brilliant system to the next level.
What problems is the product solving and how is that benefiting you?
Before moving to 3CX, our telephony setup was fragmented, inconsistent, and—frankly—expensive. Each school had its own legacy phone system, with varying suppliers, support contracts, and no way to centrally manage anything. The secondary schools alone were each paying upwards of £10k a year just to keep outdated systems alive.
3CX brought everything under one roof. We now have a fully integrated, centrally managed phone system across 20 sites, with unified extension dialling, remote capability, and SIP-based flexibility. Every staff member—whether based at a school or working remotely—has their own extension, which has vastly improved internal comms, safeguarding follow-ups, and emergency coordination.
It’s also saving us a huge amount of money. What used to cost tens of thousands across various schools is now under £10k a year total, including SIP lines. That’s a serious budget win for a Trust of our size.
But it’s more than just cost-saving. The ability to make and receive calls from laptops or mobiles, especially during lockdowns or school closures, has been invaluable. Our MIS system integrates beautifully with 3CX’s click-to-call, so when you're chasing parental contacts, it’s smooth and fast—no more scribbling numbers or navigating phone trees.
Overall, 3CX has helped us move away from outdated telephony towards a cloud-first, modern, and scalable solution that meets the real-world needs of schools.

SMS / MMS features are not easy to setup.
What problems is the product solving and how is that benefiting you?
3CX is helping us solve the challenge of managing a distributed phone system by providing a unified and centralized platform for user extension management. With 3CX, we can easily configure, update, and monitor all user extensions from a single dashboard, which significantly reduces administrative overhead and ensures consistency across the organization.
Additionally, 3CX is particularly beneficial for supporting remote work. The system allows us to deploy and manage remote extensions seamlessly, giving remote employees full access to the phone system as if they were in the office. This has greatly improved communication, flexibility, and productivity across our teams, regardless of location.

What do you dislike about the product?
I don't really have a downside for 3CX. The only thing I can think of would be possibly integrating/archiving the chat with Teams.
What problems is the product solving and how is that benefiting you?
3CX is our primary phone system for our company as well as the clients that have it running as well. The internal company chat is highly used and great with informal communication. Video conferences and webinars are great to have with little to no setup on the receivers end.
