"Effortless Management and Seamless Team Communication"

4/5

What do you like best about 3CX?

What I appreciate most about 3CX is its ease of management and configuration. The platform is highly intuitive, and having all features centralized in one place really streamlines communication for the entire team. Review collected by and hosted on G2.com.

What do you dislike about 3CX?

The mobile app occasionally disconnects or fails to receive calls when transitioning between Wi-Fi and mobile data. There are also times when notifications arrive later than expected. Review collected by and hosted on G2.com.

What problems is 3CX solving and how is that benefiting you?

3CX has made managing our phone system much easier. We no longer depend on physical desk phones or complicated hardware installations. With everything operating in the cloud, it’s straightforward to set up users, monitor call logs, and support remote staff without incurring additional expenses.

Hey Juan! Thanks for your detailed review.

We're glad to hear that the ease of management and centralized features are delivering value for your team, especially in supporting remote work.

Regarding the mobile app disconnections or delayed notifications, these are typically related to device OS limitations or network switching between Wi-Fi and mobile data and not 3CX itself.

Let your IT admin or 3CX Partner know if these issues persist - they can help fine-tune the setup for more consistent performance.

"3CX Simplifies Communication, but Mobile App and CRM Integration Need Improvement"

4/5

What do you like best about 3CX?

As a Sales Executive, I like how 3CX makes client and team communication easy and reliable. The call quality is great, and having calls, chat, and video in one platform saves time. The mobile app is convenient for staying connected while working remotely or traveling. Review collected by and hosted on G2.com.

What do you dislike about 3CX?

The mobile app sometimes lags with a weak internet connection. Setting up new extensions can be a bit technical, and more CRM integration options would make it even better. Review collected by and hosted on G2.com.

What problems is 3CX solving and how is that benefiting you?

3CX makes my daily communication with clients and teammates so much easier. Instead of juggling different apps for calls, chats, and meetings, everything is in one place. It helps me respond to customers faster and stay organized with follow-ups. Even when I’m working remotely or traveling, I can easily connect with clients through the mobile app — which really helps me close deals more efficiently. Review collected by and hosted on G2.com.

"Effortless Digital Calling, Always Connected"

5/5

What do you like best about 3CX?

What I like most about 3CX is that it truly functions as a digital phone. It's very easy to use—once I open the app, I don't have to keep logging into web pages repeatedly. If I need to go somewhere, I can simply take my laptop with me and stay connected through 3CX, as long as I have a stable internet connection. Review collected by and hosted on G2.com.

What do you dislike about 3CX?

What I find particularly frustrating is how difficult it is to edit existing contacts. In fact, it's often simpler to just delete them and create new ones instead. Review collected by and hosted on G2.com.

"3CX : A Centre Solution"

4/5

What do you like best about 3CX?

First, I liked about 3CX is its user friendly interface. We can easily use its management console. It also have amazing features like call recording, web conferencing, video chats and also integrate with other platforms like facebook etc for chat. In today's world, It is important to provide wide network of partners and various channels and 3CX is one of them . Also easy to install on cloud like private or public. The main important thing is data confidential in which our data is secure and confidential means no data uploads to third parties. Overall, 3CX is easy to control, manage and use with amazing facilities. Review collected by and hosted on G2.com.

What do you dislike about 3CX?

No doubt, 3CX provides best features to us but sometimes it has compatibility issues. Earlier, I use my old device in which I have some minor SIP device connecting issue. But later, 3CX's support helped me for resolving this type of issue. So , Users need to ensure their current hardware is compatible to avoid additional setup complexity. And according to my observation, 3CX mobile app have inconsistent quality of call and delay in notifications. They also provide limitations in their free version so need to upgrade for high business. I hope, they will fix in their new updates in future. Review collected by and hosted on G2.com.

What problems is 3CX solving and how is that benefiting you?

Better customer insights and increased efficiency with cost saving are benefiting us. They provide regular updates, maintenance and ensuring secured communication with encrypted messaging facility. Each software has dream to keep going number one in eye of their customers by providing best customer service and in same way ,3CX enhanced customer service by efficiency support and integrate with CRM system that allows for real time customer information access.

The platform is user-friendly, offering distinct versions of its website and app for both computers and mobile phones and easy set up. Review collected by and hosted on G2.com.

Hello Karim! Thanks for your feedback. We're glad you find the platform user-friendly and useful across both desktop and mobile.

Regarding reporting, with the V20 Update 6, we introduced Grafana integration, which offers significantly more customizable reporting compared to earlier versions. You may want to explore this option if you haven’t already. :)

On call quality, this typically depends on network conditions or device-specific factors. If issues persist, we recommend checking your local setup or consulting with your IT admin or partner to optimize performance.
