Brilliant tool .

Pros

The best way for coordinating call campaigns I know of .What I like best is how organized the listings / tasks are .For me ,that makes them easier to go through and helps keep track on my progress and keep me motivated .

Cons

Works better when complimented by additional calling and / or texting apps . I cannot think of anything else to complain about .

Telephone System Game Changer

Fantastic product, we left Mitel for 3CX and have never looked back. Highly recommend it and would dare anyone to copy us.

Pros

Depending on the options available and including engineer costs we found 3CX to be 60-70% cheaper than the likes of Mitel, Avaya, Alcatel and the like.

It does everything that they can do and has open connectivity with open\transparent licensing , so the more you use or the larger your business the more you will save.

Cons

3CX can be installed by anyone and some seem to think it is as easy as click, click click, the only bad thing is that you need to ensure that your partner is experienced and has completed large 3CX projects successfully.

Set up your office remotely on the cheap .

Pros

3cx reduces costs ,whilst increasing convenience .I can redirect phone lines to wherever you are ,at a reduced cost,while giving you flexibility you'll never have at an office .Can't recommend enough !

Cons

No significant complaints I can think of .If you get a lot of incoming calls ,micromanaging them can take a lot of time .

Adaptable and Progresive

I have managed 3CX for my company for over 6 years. During that time we have gone from hosting the PBX on Windows to Hosting on a Digital Ocean Linux VM. 3CX is much more stable on Linux. With a variety of hosting options, you should be able to fit 3CX to your environment and wallet size. Even having an always on backup server is an inexpensive, but necessary endeavor that will keep your employees and clients happy. 3CX is a very competitive option, with many PBX providers that I have queried not even wanting to attempt to compete against the 3CX PBX.

Pros

New Features added regularly
inexpensive
multi-platform
mobile
fully featured for call centers or standard business pbx
High Available backup PBX

Cons

documentation can be outdated at times
reporting is not the best

Great and easy to use

I love that i canbe reached without givong out my personal number. This way i know when work calls are coming through and personal calls. Easy, user friendly interface and semi customizable!

Pros

The app allows me to take office calls while I'm at home or out of the office, without giving out my personal number. Ive got my own extension and voicemail. From our office phone we are able to see if our guests (hotel) are using the phones in their rooms amd can easily xfer calls to guests or staff.

Cons

When the phone rings..it also rings through the office desktop and that feature needs to be disabled every time we login. No other complaints!

3CX Phone for Windows - EndUser review

This system is pretty reliable from my end user perspective. The voice mails come to my inbox quickly which is nice. I would recommend this to anyone with a business of the size where I work, we have around 80 employees.

Pros

3CX is easy to operate for me as I am an end user. I receive calls that are transferred to me and I rarely get any complaints that the call didn't make it to me or was dropped in the process. It is also easy to transfer calls to other people or call out by just typing the first couple of letters in the person's name. I can choose their extension or their cell phone if they are listed in our directory.

Cons

I have to restart the software from time to time because it will stop working. I also have some issues with the log of incoming and outgoing calls. I would like to be able to call someone right back if they just called and I don't have their phone number. Some calls are remembered and some are not, it seems random. I can see the number as it comes in but if I need to call that person back sometimes their number doesn't remain in the log, I do not know why.

Nice phone system if you can find support

Pros

We like the phone system and it functions most of the time.
It doesn't require complex hardware solutions
It is full features

Cons

Less of a product issue and more of a support issue. We have a 3CX phone system, but find it near impossible to find someone to support it in the midwest. Some companies are willing to do project work and replace it, but nobody seems to want to support it on a day to day basis.

Affordable calls

Pros

3CX is great in making calls affordable and coordinating them in useful fashion ,by organizing the dialing campaigns by the metrics you can determine .

Cons

Seeing as how it is free to use ,there shouldn't be much to complain about .If I had to pick something , the program looks outdated .

Unuseable

They never give you any support or license keys after you've paid them their fees I would stay away from this company

Pros

I like this product because it's works with Windows and it has a nice cell phone and it looks like it's designed well but I was never able to use it because unable to get license key after I paid for it

Cons

This company is very bad. There's no way to get in touch with them there's no support there's no phone number if you try to send them an e-mail you have to have a license key to put in there's no way to get in touch with them and if you send them an email under new customer they never get back to you I have sent them several emails with no response

Just Meh

Pros

Accessibility from mobile phone brings the office to your home!

Cons

Bit laggy, and some of the promised features don't work as well as advertised. They only work in the "perfect" conditions.

A powerful and sensibly priced SIP based VoIP system

We needed a fully featured phone system for a few users. Although we do not have many employees, we need the same features to deal with inbound calls from our customers, and integration into 3rd party contractors we use. 3CX allowed us to integrate into external systems and pass calls (for free) to SIP extensions. The Snom phones we use are fully supported and the system feels top notch.

Pros

The software is completely free and you only pay a simple licence for concurrent calls. This allowed us to build out a complex phone and IVR system for a small business and it handled our exact needs. We can scale when we plan to as we grow.

Cons

The iOS application does not remain open if switching to another application. Each time the app is opened, it takes a couple of seconds to register. There isn't a setting to override this.

Inexpensive phone software for Windows and Linux

Pros

Going into a phone system w/o much knowledge of VOIP systems, I found 3CX to be very intuitive and easy to learn. The pricing between it and our SIP provider allowed us to save in the first year of using it. 3CX, as a company, is quick to release solid patches and new versions.

Cons

Some features, like texting, would be nice to have, but this is really grasping at straws. The menu system for configuration has been "flattened", which does make it more difficult to navigate.

Pros

3cx represents great value for your investment .It reduces phone costs several times over and makes connecting to everywhere in the world and setting up calling campaigns easy .

The design is beginning to look outdated and you need some help online when originally setting up the lines . Not really much else to complain about , 3cx is great.

Nice software to make calls but I needed some time to get used it

Pros

I like the different features it offers. E.g transfer calls, hold calls, direct to the voicemail, change the theme (yes, I like it!), and you can even chat with users.

Cons

Before one of my colleagues showed me how to install it, I had no idea how to do it.

First Time VOIP Made Easy With 3CX!!

I just recommended this to a friend of mine who recently opened a small business and wanted a a nice VOIP software ...

Pros

Cross platform software made easy! I really enjoy the extra line that gets added to your smart phone! Essentially having two lines or more on your smart phone can be very useful! Making and setting up the IVR is simple compared to some of the other big name VOIP companies! And best of all their customer support is touch notch! Very Friendly

Cons

The only downside to the software that I didnt like was once they added the QR Scan for mobile devices.

Everything you need in a phone system .

Pros

3CX really takes your calling efficiency to the next level . Extremely easy to install and and the subsequent process has been automated ,everywhere where automation is possible .It also significantly reduces costs .

Cons

As it is to be expected ,3CX is heavily dependent on a good internet connection .While calls work like a charm ,I feel like sending out text messages can be developed further .

Great phone system for the money

low cost pbx

Pros

This software is lightweight, full featured and it works really well for the money. They've done a great job in adding features all the time.

Cons

Recently they've been adding too many updates too quickly which has caused some unneeded glitches. They have fairly quick response time.
