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.

Asterisk

Sales Manager

The openness of the system and ability to create so many solutions based on this little piece of software. It is a great foundation for creating a telecommunication solution for yourself.

Network and Systems Administrator

Presently, I am including students in the system such that while on campus they can benefit from free phone calls while on campus. Asterisk is really amazing.

Need to be careful not to leave it open to fraudulent calls. As a CLI based tool it can be a bit confusing to install from the tgz.

Best solution for an in-house PBX should you have the ability to manage and maintain it.

Especialista en infraestructura

It is a very stable and practical voice over ip system, you can integrate it with practically any system and the functionality is perfect.

desginer

It entails a number of severe security threats. And We don't obtain the complete event of Outdial parameters in the Asterisk manager interface layer.

Network Infrastructure Manager

Cost wise it's very cost effective and that's why I believe it's a top tier solution you should consider for any size of business.

Associate Systems Engineer

Those are the facts i most liked in implementing Asterix and it supports both Linux and BSD operating systems.

IT Manager

The best PBX solution for small offices with multi locations, different dial rules, etc. All of my colleagues started working from home on the first day of pandemic.

IT consultant

No administration tools, no user interface, lack of commonly needed extensions like phone handset management and voicemail.

Head of IT

Overall, as an open source system it is a great value for money.

I have setup and managed many asterisk installs for various use cases and love working with it, all be it I'm very familiar by now but it's not difficult to get the hang of it.

Real Estate Broker

It removes the need for purchasing expensive hardware. There is a large community of users around the world that will help troubleshoot and setup.

Documentation is not good enough. When you have some problem it is hard to find the solution.

Getting started and setup is a bit difficult for the non technical.

Senior Technology Architect

OpenSource, free, a lot of features. It became an industry standard and provide certification and a real user support / community support.

However, while it is full featured, it has no built-in GUI, either for admins or users. Using a package like FreePBX is essential for business deployments.

System Administrator

Asterisk is a flexible VoIP platform that allows interaction with telephone systems within the institution nationwide, also allows integration with specific business applications.
