3CX Delivers a Smooth, Secure Office Line on My iPhone
Reviewed on Oct 27, 2026
Review provided by G2
What do you like best about the product?
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.
What do you dislike about the product?
Nothing at all. It is a great product with a high ROI and no performance issues.
What problems is the product solving and how is that benefiting you?
It has simplified the process of onboarding and connecting our staff as well as safely and securely connecting our staff to end users. It capitalizes on the equipment everyone already has and knows how to use--their mobile phone. This saves the company on equipment and maintenance costs while also affording employees an ease of use and seamless connectivity.

Seamless Zoho CRM Integration with Click-to-Call and Great Texting
Reviewed on Oct 27, 2026
Review provided by G2
What do you like best about the product?
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.
What do you dislike about the product?
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.
What problems is the product solving and how is that benefiting you?
Before 3cx, we didn’t have any texting capabilities, and adding them has opened up a whole new channel for our sales reps and fulfillment teams to communicate. The ring groups in 3cx also work seamlessly alongside our call tracking metrics and auto attendant, which helps everything flow together smoothly.

Efficient Communication with Seamless CRM Integration
Reviewed on Sep 18, 2026
Review provided by G2
What do you like best about the product?
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.
What do you dislike about the product?
Sometimes I find 3CX's interface a little complicated, and I think the setup and configuration could be simpler.
What problems is the product solving and how is that benefiting you?
3CX tracks call records by team members, helping us monitor recordings and daily activity. We efficiently manage call logs, and with Pipedrive integration, we dial directly from CRM, eliminating manual number entry.

Unmatched Value: 3CX’s Feature-Rich PBX That Just Works
Reviewed on Jun 05, 2026
Review provided by G2
What do you like best about the product?
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.
What do you dislike about the product?
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.
What problems is the product solving and how is that benefiting you?
It provides us with a best-in-class, easy-to-adapt, full-stack solution to provide our reseller/MSP/SP partners. When assisting a partner to build out their VoIP offering, you won't get far relying on a platform that has a huge technical learning curve or a complex up-front model structure. They want a solution that works and that their teams can work with so they can get back to growing their business. That is the problem 3CX solves for us.

Handy Second Number, but Calls Dropped and Random Holds
Reviewed on May 05, 2026
Review provided by G2
What do you like best about the product?
It was nice having a secondary way to use my cell phone, so I didn’t have to share my actual number.
What do you dislike about the product?
My calls kept dropping, or I would be put on hold at random.
What problems is the product solving and how is that benefiting you?
This issue was never resolved, so we ultimately ended up switching providers.

Easy Self-Hosting, Great Performance, and Fair Pricing
Reviewed on May 05, 2026
Review provided by G2
What do you like best about the product?
The fact you can self-host on a simple server, while retaining good performance, is a great feature. Easy to use, rich in features and fair pricing.
What do you dislike about the product?
There’s a noticeable lack of native AI features, and it feels like competitors are catching up quickly on that front. Integrations are also fairly limited, largely because there isn’t an open API.
What problems is the product solving and how is that benefiting you?
Possibility of calling locally colleagues thru their extension, calling phone numbers, but also doing video calls.
