What do you like best about the product?
I like 3CX for its simplicity, reliability, and ease of use, along with flexible management and strong call-handling features.
What do you dislike about the product?
> 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.
What problems is the product solving and how is that benefiting you?
3CX solves the problem of managing complex and expensive phone systems by providing a simple, cost-effective, and centralized VoIP solution. It benefits me by making call handling, user management, and remote access easy while reducing telecom costs and administrative overhead.

User-Friendly, Yet Setup is a Hurdle
Reviewed on Jan 28, 2026
Review provided by G2
What do you like best about the product?
I like 3CX for its ease of use and its user-friendly interface. It's also great for making outbound calls and facilitates communication with my Australian clients, making the process easier and faster.
What do you dislike about the product?
The interface, though user-friendly, doesn't work like an actual phone system. The calling feature requires going through a lot, and it doesn't really look or function like a traditional phone system. Also, the text messaging system is another area that could use improvement. It took me a long time to set it up, so it wasn't easy.
What problems is the product solving and how is that benefiting you?
I use 3CX to make communication with my Australian clients easier and faster, especially being based in The Philippines.

Reviewed on Jan 22, 2026
Review provided by G2
What do you like best about the product?
3CX is best for its cost savings flexibility and ease of use. It also delivers unified communications along with strong CRM integrations, making it a powerful, affordable, and modern alternative to traditional phone systems.
What do you dislike about the product?
3CX often focus on frequent, disruptive updates, a perceived shift away from user-friendly perpetual licenses toward recurring revenue, unreliable performance in the mobile app, and support that is either poor or available only on a commercial basis.
What problems is the product solving and how is that benefiting you?
3CX addresses the challenges of outdated, expensive, and inflexible phone systems by providing a unified, software-based communications platform. It brings calls, chat, and messaging together in one place, which can lead to meaningful cost savings, improved mobility for remote work, and simpler day-to-day management. It also helps support better customer experiences through capabilities such as CRM integration and unified communications.

Constant Changes and Costly Support
Reviewed on Jan 11, 2026
Review provided by G2
What do you like best about the product?
I like the 3CX GUI interface, it is nice, accessible, and understandable.
What do you dislike about the product?
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.
What problems is the product solving and how is that benefiting you?
Its GUI interface is accessible and understandable.
