Call Center Customer Service Representative 

The quality of the recorded calls is amazing and it makes them very useful for training purposes. 3CX gives you a lot of freedom to organize the call list in a way that works for you.

Estimator

Great integration with existing system, and helped us streamline the forwarding/holding/transferring process. VM to inbox was amazing.

Software Developer | Network Engineer

Support from the manufacturer is simply outstanding as there knowledge base and support team go the extra mile to help you.

Freelencer

Technical support was outstanding in assisting with the troubleshooting and setup.

I highly appreciate 3CX's compatibility with multiple SIP platforms and I really like the option of adding multiple profiles which can be very useful when working in multiple work environments.

Vice President Of Technology & Operations

It was inexpensive, there are local experts, easy to setup, and their new features continue to improve an already great platform.

Owner

It just works all the time. Windows or Linux (Debian) both versions whether in the cloud or on hardware are solid, solid, solid.

Student

3CX was a good start for my lab's VoIP controller, it covered the bases in terms of operating physical phones, and was a great learning experience.

Person

Great, ease of use, cost savings and mobility is the ticket in the modern world.

Customer Service & Inside Sales Manager

The vendor that we bought it from spent no time training us and we had several system issues that tarnished our experience.

Insurance Executive

We can make and receive calls, send messages, and hold video conferences seamlessly. The software also integrates smoothly with Microsoft 365, which has significantly improved our team's efficiency.

manager

We stopped wasting money on LANDLINES and chose 3CX as out internet phone PBX.

Professional Photographer

I like to use in windows and works wonderful with SIP Extensions without problems.

It can be slow and it's closed-source, which really annoys us.

Director

Errors trying to open the platform even though firewall off. Not sure the difference between the "management interface" and the "webclient.

Risk Operations Analyst

I like that this caters to be a substitute for a physical telephone within my organization. It is fast and easy to use more importantly, I could easily access it through my phone using the app.

The price can be FREE if you are a small office. Still, even for a larger organization the pricing is extremely affordable.

Network Manager

The interface is extremely intuitive and very user-friendly. Also, the install instructions are extremely easy and I was able to set up a virtual Debian server and install 3CX in under 30 minutes.

co-owner of a dental practice

Well worth having on my team. Best phone software out there.

The thing I like most about this software is the cost and easy of use.

Set-up was easy and painless. The integration is top-notch, as the only employee at a busy office, being able to monitor calls and voicemails from my cell is incredibly helpful.

Got my phone number that the other company was refusing to transport.

Document Control Manager

Overall my experience using Intermedia Unite has been positive. Customer service will contact you pretty quickly if you have issues.

As of this writing, I have no reason to switch to any other phone service.
