3CX Reviews in June 2026: User Ratings, Pros & Cons

MSP Network Engineer with 10 Years VOIP Experience

What do you like best? As an MSP engineer I have used a lot of VIOP systems from Altigen, Cisco, Nextiva, Star2Star, Zultys, and Avaya both on premise and in the cloud and the one thing that 3CX has and that all of them lack is that 3CX is server software that fits into existing IT infrastructure so easily. I can run it on premise or in the cloud on Windows or Linux and all of my existing monitoring, networking, and back up work flows work with it. That makes deployment and ...

Cost-efficient Phone Solution

What do you like best? The cost savings were huge. We have many numbers with very little external usage, other than our sales staff. As such, excluding overhead on our IT department, we went from ~$35/month/line to $7/month/line pricing for hundreds of users. What do you dislike? Missing some features that I would like, such as single sign-on, or a RESTful API access. With those features 3CX would be everything we have been looking for. Also, I wish more company branding was an option ...

It makes VOIP simple to scale

What do you like best? We evaluated all the major players in the market, and 3CX won in almost every category.

All around excellent PBX that allows the administrators and users be in control

What do you like best? The customization and control over call flow and features. We can utilize 3CX's flexibility to configure and install a customer's system in just about any way they want.

Obviously multiple versions behind is an issue but when it comes to being 1 update behind, that can be annoying. Recommendations to others considering the ...
