"Great switchboard"
5/5
What do you like best about 3CX?

We've been using 3CX for a while now and are very satisfied with how it has evolved. We originally replaced our traditional switchboard with 3CX, and the benefits were immediately clear — especially the mobile app and desktop application, which allow us to make and receive calls from anywhere, as long as there’s an internet connection. This flexibility proved invaluable during the Covid lockdowns. We've are planning on using the WhatsApp integration, to manage customer communication from a single platform. Overall, 3CX continues to be a reliable, flexible, and cost-effective solution for our communications needs.

What do you like best about 3CX?

I like 3CX for its simplicity, reliability, and ease of use, along with flexible management and strong call-handling features. Review collected by and hosted on G2.com.

What do you dislike about 3CX?

> I dislike that some advanced features and customizations can be limited, and troubleshooting can sometimes be less intuitive compared to more mature or fully cloud-native phone systems. Review collected by and hosted on G2.com.

Response from Monika R of 3CX

Hey Rahul! Thanks for your review. We’re glad to hear 3CX meets your needs in terms of simplicity, reliability, and cost-effectiveness. That’s the core of what we aim to deliver.

Regarding advanced features and troubleshooting, while 3CX is not fully cloud-native by design (to give you more deployment flexibility), we continue to improve the admin experience. With V20, a more unified interface and tools like Grafana for reporting are helping bridge that gap.

If you ever run into limitations or need help with customization, we also have a global network of certified partners who can provide hands-on support when needed.

"Constant Changes and Costly Support"
0.5/5
What do you like best about 3CX?

I like the 3CX GUI interface, it is nice, accessible, and understandable. Review collected by and hosted on G2.com.

What do you dislike about 3CX?

They change prices and features every 5 minutes, which is unbearable. Support is also an issue; previously, we had access to support for free, but now everything is paid. The management of 3CX is pathetic with the removal of perpetual licenses. Prices are constantly increasing and features change arbitrarily. Our operator is no longer on the list of certified operators, which complicates things. Review collected by and hosted on G2.com.

Response from Monika R of 3CX

Hi Anthony. Thanks for the feedback. We understand your frustration, but just to clarify a few things:

Pricing: We don’t change prices “every 5 minutes.” Like any tech company, we review pricing periodically to align with our long-term strategy. Adjustments are not arbitrary, and we aim to keep 3CX cost-effective, especially when you compare features vs. cost with other PBXs in the market.

Support: Free support is still available for certified 3CX Partners. For end customers, support is typically provided through the partner who manages the system. This structure helps us scale and provide more localized service.

Licensing: The move away from perpetual licenses happened some time ago. Subscription licensing is now the standard and it allows for faster innovation, regular updates and better security.

Certified Operators: We maintain a list of supported SIP trunk providers to ensure full compatibility. If your provider is no longer certified, our global partner network can often help you work through this or recommend an alternative.

We respect that this might not align with your preferences, but we don’t believe the changes are as extreme as described. 3CX remains one of the most feature-rich and affordable solutions in its class.

"Powerful and cost-effective business communication solution"
5/5
What do you like best about 3CX?

3CX is an all-in-one communication tool that makes business calling and conferencing very easy. What I like best is how flexible it is — you can use it on desktop, mobile, or even directly from a browser. The call quality is clear, and features like video meetings, live chat, and call recording give a professional edge without needing multiple tools. It’s also cost-effective compared to traditional phone systems Review collected by and hosted on G2.com.

What do you dislike about 3CX?

The initial setup can feel a little technical for non-IT users. The mobile app sometimes lags compared to the desktop version, and more user-friendly documentation would make onboarding smoother. Review collected by and hosted on G2.com.

Response from Monika R of 3CX

Hi Shamas. Thanks for your review. We're glad to hear 3CX has helped streamline your communication, reduce costs and support remote teams effectively. We appreciate the feedback on setup complexity, mobile app performance and documentation - your input is noted. For businesses needing assistance during onboarding, our global partner network is also available to help.

"Stable and Feature-Rich, but Lacking a Public API and Strong Reporting"
3/5
What do you like best about 3CX?

3CX is a stable pbx, and has got many useful features. Review collected by and hosted on G2.com.

What do you dislike about 3CX?

Unfortunately, 3CX seems to be miles behind other pbx systems, with the lack of a public api and subpar reporting. Review collected by and hosted on G2.com.

Response from Monika R of 3CX

Hey Jack! Thanks for your review. We're glad to hear 3CX is handling your daily call volume reliably and meeting your telephony needs.

Regarding reporting, with Version 20 Update 6, 3CX introduced Grafana integration, which provides more advanced and customizable reporting capabilities beyond the built-in tools. We'd highly suggest looking into that if you haven't already!

We appreciate your feedback.

"3cx is the most underrated VOIP platform out there."
5/5
What do you like best about 3CX?

We are a large, two-campus Residential Addiction Treatment center for Men and Women. We have used 3cx exclusively for 6 years now. We have been able to do so many amazing things with it.

Our entire phone system runs on 3cx

Our Intercom System Runs on 3cx

Our Payphones for our students runs on 3cx

The gate protecting our campus is controlled by 3cx

We have full control over rules, over our call routing and our IVR.

We recently switched to hosted 3cx in the cloud and all of the issues we had with hosting manually were completely solved by switching to the cloud. Our uptime has been 100% since moving to the cloud.

We love 3cx and hope to continue to be able to afford it moving forward. Review collected by and hosted on G2.com.

What do you dislike about 3CX?

The only downside for us as a non-profit is the pricing. We would love for there to be more affordable pricing for non-profits but for a small business or enterprise deployment the price is very manageable. Review collected by and hosted on G2.com.

Response from Monika R of 3CX

Hello Christopher! Thanks for your review. We're glad to hear that 3CX has been a reliable and versatile solution across your campuses, from phones and intercoms to gates and IVR. It's great to know the move to our hosted cloud service resolved previous issues and improved uptime. Regarding pricing, we do offer a completely free version: 3CX SMB FREE, which supports up to 10 users and may be a good fit for some non-profit setups. We appreciate your continued support and feedback.
