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.

Hosting 3CX PBX On My Company's Server/Network

3CX is straightforward to configure and easy to use. Customer support is very good as there is always a knowledgeable person available to help with any questions or problems.

Hosting and managing a VOIP phone system like 3CX does require additional time for updates and maintenance.
What problems is the product solving and how is that benefiting you?
I was able to create a bridge to connect our 3CX PBX with our factory's PBX in Italy. We can now reach our partners by simply dialing their extension.
After 10 years I threw in the towel and left
What do you like best about the product?
New features each year. Has a good address book and integration with smart phones. I liked being able to use older desktop phones that the users were familiar with. It didn't drop support for those phones and force me to buy new models.
What do you dislike about the product?
The pricing continued to increase each year. I started at $150 a year then it grew to over $700. My perpetual license was switched without notice to a required subscription license. Support said I was supposed to read a forum post.
I could never get the share screen feature to work in the web meetings. Seemed to be firewall issues on either end.

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.

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
What problems is the product solving and how is that benefiting you?
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.
