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.

OnSIP is great to work with. They are always there to help out and get something resolved.

We have implemented several installations with them and the ease of use is amazing. Being able to setup the entire install from my desk before we go is also a very solid plus.

From my experiences, we love the ability to build out our own system to our design. Not having to settle for an out of the box, get what you got solution.

The best part is our clients get a great product at half the cost of some of their competitors.

My favorite part of OnSIP is their amazing customer service.

The mobile application is great. I also like that I do not need to use the receiver when talking, the call comes over your computer speakers.

The voip service is great. Adding new users, features, equipment, etc is super easy.

Head of Information Technology

But we are losing usage to communications apps.

Admissions Director

I love that I receive an email saying I have a voicemail-I can easily listen to the message from my computer.

Head Of Customer Experience

Onsip is great and easy to use. Onboarding my team was a breeze.

I was making a leaving a message and received an incoming call-it kept beeping and it was confusing how to navigate this situation.

Admin Assistant

OnSIP's web portal and mobile apps are known for being user-friendly for both administrators and regular users. If you found the system easy to navigate and manage, this is a noteworthy advantage.

IT Manager

We switched from "regular" phone service that didn't work at all half the time. The sound quality, the cost, the versatility and support are outstanding.
