3CX allows me to use my mobile phone as an office phone without having to share my personal mobile number. It gives me the security and peace of mind of an office line no matter where I am. It integrates seamlessly with my iPhone, supporting both calls and texts, and the performance has been consistently smooth. I haven’t run into any issues—only an easy, straightforward experience. Overall, this product has genuinely improved my workflow and kept me better connected. Onboarding and training were simple and intuitive, and the pricing structure feels reasonable and well worth the investment. Review collected by and hosted on G2.com.

Nothing at all. It is a great product with a high ROI and no performance issues. Review collected by and hosted on G2.com.

In my opinion, 3CX is a robust, software-based IP PBX with a unified communications platform design that allows us to replace a traditional hardware phone system. Review collected by and hosted on G2.com.

What I’ve found is that, unlike plug-and-play cloud solutions like Zoom that can be easily managed by a regular office manager like me, 3cx requires a solid understanding of networking, including firewalls and server administration. Review collected by and hosted on G2.com.

The web client makes day-to-day calling straightforward without needing physical desk phones or heavy setup. Getting team members configured with their own extensions takes very little time. and having voice, status presence, and quick video meetings right inside the browser communication organised without constant dropouts.

Initial DNS and firewall configuration can be tricky if you move beyond the standard cloud setup. some of the advanced call routing rules and IVR menu workflows also feel somewhat dated compared to modern collaboration tools, requiring you to dig through submenus to find simple settings.

I love how it integrates with our Zoho CRM. With click-to-call, when a current client calls in, I immediately know who it is and can pull up all of their contact information in our CRM. Texting is great, too. Review collected by and hosted on G2.com.

I wish the web version had hotkeys. Also, some parts of the UI could be simplified. For example, when you save an option in a user profile, you have to click Save in two different places for the changes to take effect. Review collected by and hosted on G2.com.

3CX is quick and easy to set up. They don’t bill per agent or extension; instead, they charge per concurrent call, which makes it cost-friendly when you want to scale your call centre operations. Review collected by and hosted on G2.com.

Reporting. The built-in reporting features are very limited and static. You can’t customise even a basic report. The Freshdesk integration also doesn’t provide full CTI capabilities, and to get that you have to use a third-party tool at an additional cost. As a result, if you want to make sense of your data, capture all the metrics you need, and visualise them properly, you end up exporting the data and doing the work manually outside of 3CX.

The licensing structure, vendor independence, and overall ease of management stand out to me. Review collected by and hosted on G2.com.

3CX's feature set to price value is all but unmatched in the industry. Emerging AI tools combined with an easy-to-deploy, use, and maintain PBX. 3CX is a no-brainer for technical directors, service providers, and telecommunications resellers alike, simply because it just works and it works well.

There are a few minor, niche reporting tools I’d personally like to see, mainly for my own and my partners’ specific use cases. That said, my “complaints” are really just edge-case requests, which honestly speaks well of 3CX overall. Review collected by and hosted on G2.com.

I like how easy 3CX is to use. It stays on my desktop when I open other programs, and it's easy to connect my Bluetooth headphones. I can use the app on my laptop or mobile, and my phone app connects when I'm away from my building, so I don't have to take my laptop to receive calls. I can review my calls, see how long I was on the phone and when a call started, and call a number back without searching the database again. I can also put a client on hold, conference in a teammate for help, and add team-member nicknames for quick dial. The setup was very easy, and I think 3CX is really good.

I find the ringtones a little jarring and would like a different option, though there may already be a setting to change them that I just haven’t looked into. Review collected by and hosted on G2.com.

it records the calls, we can also barge in the calls, we can integrate it with other official tools and softwares and best is the UI and UX Review collected by and hosted on G2.com.

without internet it makes issues. sometimes some one wants to call me and if he does not add 0 followed by the number then the call wont connect Review collected by and hosted on G2.com.

I like that 3CX has an easy-to-use interface, a super fast GUI, and strong connectivity. The integration with Pipedrive is particularly helpful because it allows us to make calls directly from the CRM, which means no manual entry of phone numbers into 3CX. I also appreciate the call management, call recording, and mobile app features, which enable us to stay connected and respond immediately, even when I'm not at my desk.

Sometimes I find 3CX's interface a little complicated, and I think the setup and configuration could be simpler. Review collected by and hosted on G2.com.
