"Practical and Intuitive, but Needs Aesthetic Improvements"
5/5
What do you like best about 3CX?

I value the practicality of 3CX, which makes operations much more efficient and easy to manage. The platform's optimization is remarkable, with a lightweight app that doesn't consume many resources yet still offers comprehensive functionalities. Additionally, it is intuitive, which facilitates communication between departments within the company, integrating the different areas in a cohesive and efficient manner. I also appreciate how simple and quick the initial setup of 3CX was, allowing for a smooth transition without disrupting daily activities. The confidence in the product is so high that I would give it a score of 10 on a recommendation scale. Review collected by and hosted on G2.com.

What do you dislike about 3CX?

I think that 3CX could improve in aesthetics. Currently, I miss more native aesthetic options to customize the app to my liking. Review collected by and hosted on G2.com.

"User-Friendly Interface and Handy Phone Extension Integration"
4.5/5
What do you like best about 3CX?

The user friendly interface is one of the major eye catching feature-one of the best features is that your personal phone can be connected via an extension keeping you connected to the main office line. Review collected by and hosted on G2.com.

What do you dislike about 3CX?

The only disadvantage would be the constant glitching when adding new audio hardware- manually you need to change it since some times it tends to switch between computer integrated speaker rather than the headset Review collected by and hosted on G2.com.

Response from Monika R of 3CX

Hey Stephanie! Thanks for your review. We're glad to hear you find the interface user-friendly and that the extension functionality is helping you stay connected on the go.

Regarding audio device switching, this is often influenced by the operating system’s audio settings rather than 3CX itself. We recommend checking your device’s default audio configuration to ensure the correct input/output is consistently selected.

"User-Friendly, Yet Setup is a Hurdle"
4.5/5
What do you like best about 3CX?

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. Review collected by and hosted on G2.com.

What do you dislike about 3CX?

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. Review collected by and hosted on G2.com.

Response from Monika R of 3CX

Hey Louise! Thanks for sharing your experience.

We’re glad to hear that 3CX helps streamline communication with your clients in Australia, especially across regions like the Philippines, where remote connectivity is key.

As for the setup concerns: For those who prefer assistance, we have a worldwide network of certified 3CX Partners who can help with deployment, configuration and even texting setup.

"3CX is easy to setup and very user friendly"
5/5
What do you like best about 3CX?

As the administrator of our 3CX system, I find the implementation and configuration process to be very straightforward and easy to follow. Setting it up does not take much time, allowing you to get started quickly. I appreciate the availability of a cloud option, which eliminates the need for on-premise hardware. Physical handsets are also unnecessary, thanks to the mobile client and desktop software. Their customer support is excellent, with knowledgeable staff who resolve issues promptly. We rely on 3CX for all our communication needs. Integrating it into our existing network is simple and can be completed in under an hour. Users often take advantage of 3CX for more than just calls, using it for chats and meetings as well. Review collected by and hosted on G2.com.

What do you dislike about 3CX?

I am frustrated by how often support is withdrawn for third-party requirements such as handsets and SIP Trunk providers. If you happen to use a third-party option that is not officially supported, you won't get any assistance with configuration or troubleshooting issues. Review collected by and hosted on G2.com.

Response from Monika R of 3CX

Hello Nigel! Thanks for your review. We're glad to hear 3CX has been easy to set up, integrates well with your network and supports your daily communication needs across calls, chat, and meetings.

Regarding third-party devices and providers, our support policy clearly states that we do not offer assistance for unsupported hardware or SIP trunks. This is because we maintain a verified list of supported devices and providers that we work closely with to ensure full compatibility and reliability. For unsupported setups, we recommend reaching out to a 3CX Partner from our global network, who may be able to assist further.

Appreciate you taking the time to share your experience!

"3CX: User-Friendly, Flexible, and Cost-Effective Communication Solution"
4.5/5
What do you like best about 3CX?

3CX is extremely user-friendly and offers great flexibility for both remote and on-site communication. The interface is intuitive, setup is simple, and it integrates seamlessly with existing systems like CRM tools. The call quality is excellent, and features like web conferencing, call recording, and mobile app support make it very convenient for teams working in hybrid environments. It’s also cost-effective compared to traditional PBX systems Review collected by and hosted on G2.com.

What do you dislike about 3CX?

Sometimes, setting up the initial configuration and firewall can be challenging, especially for users who lack technical experience. The mobile app works, but it would benefit from greater stability and responsiveness, particularly when the internet connection is weak. Furthermore, customer support could improve its response time when dealing with more complex technical problems. Review collected by and hosted on G2.com.

Response from Monika R of 3CX

Hey Sohail! Thanks for your detailed review. We're glad to hear 3CX has improved your communication infrastructure and supported both remote and on-site collaboration effectively. For users needing assistance with setup or configuration, our global network of certified 3CX Partners is also available to help!
