well it is a phone system. We use 3CX to talk to our customers, we use it as webconference solution and we use it as a very lowlevel slack alternative.

3CX is a solid voip solution that offers all the features and functionality an ordinary team or company needs. Installation and maintenance is simple. The webclient is getting better and better with every version. Speaking quality is great if you use the right codecs or hard phones. We love 3CX and use this pbx since many years.

There is no documented API. Either something is supported or not. There is no possibility to get individual implementations.

Overall, I have no complaints on 3CX as we are very satisfied.

I love all the features of 3CX. I love how easy you can set it up, you can find the calls logs and recordings, plus it has a very comprehensive dashboard. Also, when we reach out to them to increase our accounts SC (concurrent calls), they are very responsive as they have a local partner from where I'm from and it was solved immediately.

The only thing I don't like about 3CX is the provisioning of the softphone as in our setup, people come and go, and we need to provision whenever there's a new employee who'll use it. I think it's better if 3CX can have the login/logout functionality on the desktop app instead of provisioning every time. But it is really negligible and not a deal breaker at all.

It is handy to have my business line call and record calls while using my cell phone. I prefer to not give my cell phone number out to customers so by calling from the app on my phone, customers do not know that I am not at my desk.

The app for my desktop changed a few years back and is now huge. It is not very convenient to leave up on the desktop anymore as it covers a large majority of my icons. When the change happened, we also were not able to use our busy light feature anymore.

Overall I've liked using 3CX. Easy to use, and efficient.

I like the efficiency of the product. Its easy to make, receive and transfer calls using this system. No need for big bulky phone taking up more room on the desk, just simply type the number in using the numbers on the keyboard, and plug in a headset to the USB port.

Its not great when the internet goes down, as the calls then drop. However this is part and parcel of not having a physical desk phone.

3cx is small or big companies the best option possible also customers not wanting to use cloud telephony 3cx still provides option to have on-prem solution

full featured phone system with no extra costs. possibility to have cloud deployed, private cloud or even on-premise!

some features are still in beta but they are already active and communication when issues rice is closely followed by support to have them asap out of beta.

The day to day operation is more streamlined and at a management level, it helps keep track of those taking calls on out various teams. It also allows us to be away from our offices but take the mobile app with us and get our VM's via email... all positives and allows us to be more attentive.

3CX has made it easier to maintain our calling network and allows us to bring its features outside of the office which aids in our day to day. The phone dial pad it self is very user friendly and the software it self has a very ease of use feel to it. As a manager it is nice to view, listen and transfer my teams calls on the fly - the logging system also allows me to keep track of activity within my teams.

Not a ton of cons to be honest, there are some issues of delays from when you ask for a function (click delay) like looking up a contact from the address book and clicking to call the contact, sometimes there is a bit of a delay. The product could use a bit of a refresh look, but overall the ease of use and user friendly Softphone does hit it's marks.

The transfer (number port) from our old company was extremely smooth and hassle free, the business wasn't impacted at all.

The phone system appears to be reliable, and the new handsets we had installed, are very easy to use, with features such as touch screen and one button voicemail (no typing in a sequence of numbers) The display is large, and you can automatically see who is "speaking" as their name appears in red on the screen. The touch screen display can show in excess of 25 extensions numbers at a touch, no more entering extension numbers.I am also really pleased with the reports I can generate, such as the calls each employee has taken in a day, all sent via email at a time specified by you, and so easy to set up.The administration features, such as setting bank holidays, Christmas day is so much more user friendly than my old system.So far, I am very impressed, there are features I haven't even explored yet.

One major issue we found was, you cannot rewind the voicemail by seconds, you can only skip to the beginning. We have very large orders left on the voicemails, and we need to be able to jump back to hear one product. You can log on via your PC, however for us this isn't the best option.We have added a ticket and hope the feature can be included.

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

It's less known so it can be confusing to employees or external participant

3CX has been an invaluable asset for our team. Its user-friendly interface, unified communication features, and rich functionality have transformed the way we collaborate and interact with clients. The reliability and cost-effectiveness of the system make it a top choice for our call centre's day-to-day work. I highly recommend giving 3CX a try.

With 3CX, everything is unified under one roof. 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.

3CX relies on a stable internet connection. Even the slightest change will impact your experience. Compared to the previous software we had, this is an ongoing issue we're still trying to find a solution to.

I would say it has been satisfactory for the price and limited use

Wase of use, good functionality and reasonably priced

Desktop app is a bit clunky, stops working intermittently and need IT people to fix it

We have been using 3CX Phone System Professional Edition for almost 3 years now. After a series of non-starter with other brand name phone systems we stumbled across 3CX. We were initially turned off that it was Windows based however this has turned out to be a HUGE benefit. Not only can we use are existing utilities and subscriptions to do backups, screen sharing, maintenance, etc, but our employees were immediately comfortable making changes and other maintenance. 3CX Phone System has features like Web Conferencing, built in screen sharing, free smart phone applications that were not initially a buying consideration for us but have become some of the most valuable and powerful parts of 3CX - and they continue to improve and release more of these valuable feature rich tools - at no additional cost. The licensing model is unique from any other phone system we've used. 3CX is licensed based on Simultaneous calls rather than total extension or lines. While the pricing is very good, its particularly good for larger offices or public spaces where extra phones are required in places they will receive little use. Other systems require you to pay full license cost for these low use phones but with 3CX, there is no extra cost.

I've noticed they are too innovative. Where most other phone system are quite stagnate and only release bug fixes, 3CX regularily release new features and is constantly improving capabilities. We have been seeing at least 2 service packs a year, each which represents leaps forward in features and capabilities. They can be ignored, though we've invested into learning and building on them

I am very satisfied with the 3 cx program, as I have been able to carry out its functions in a practical and efficient way on a daily basis. While not perfect, I think this program is very useful.

This program has provided a trouble-free calling and receiving experience from the moment it was installed on your computer. As a daily user of this tool, I haven't had major difficulties or complaints related to poor quality or connection drops.

There are few aspects of the program that I dislike. The first one is the delay in the initial connection. Although it did not record connection failures, the connection slowness makes the program less practical. Also, I notice the lack of an option to make conference calls, which is of paramount importance for my tasks. If this option were available, the utility of the program would improve.

We had a customer that had 3 different companies within the walls of the building. We were able to configure each company separately so that their rules, hours, and each had different SIP providers that needed to be configured up properly. Each had their own digital assistant and the system setup took only a few hours to complete with all the complexity that was involved. Technical support was outstanding in assisting with the troubleshooting and setup.

The 8 concurrent call Standard License is free to all companies. This makes it a perfect solution for churches, small businesses, and as the small businesses grow into medium sized businesses, the annual cost for the license with higher concurrent calls is nominal. When companies switch from the POTS lines, they need to figure out a good solution for VoIP. 3cx is lower cost than RingCentral and 8x8 as well as many other competing VoIP softwares.

Putting in supported APAP adapters is great, but when a customer has a non supported adapter, it usually works, but doesn't play nicely with the software as far as configuring it easily.

3CX has been a game changer for how I manager my time and work schedule. I can quite literally be anywhere in the world and not miss a thing. I like how there is the option to put the function on "Do Not Disturb" as well, for times you want to disconnect.

For years I have had a flexible schedule which meant I was not always physically in the office. My concern was always that I was missing calls at my desk, or that the front desk personnel would have to forward the call to my cell phone. The 3CX software seamlessly patches my calls through AND shows the extension name and number the call is coming from.

When I downloaded the software onto my iPhone, it also downloaded all of my personal contacts, which makes it harder to search easily for my colleagues and increases the likelihood of mis-calling the wrong person. I use 3CX only for work, so I do not like having my personal contacts mixed in.

Overall this is really a great product for the cost. Our IT company has been instrumental in setting this up and guiding us through the options available.

The software is very affordable compared to other products we looked into and provides an array of options - almost anything we'd need.

It doesn't integrate well between soft phone, desk phone, and app on the cell phone. Voice mail or missed calls have to be addressed individually, on each device. Also, if I refuse an incoming call on my cell phone app, I would expect that refusal to apply to the soft phone and desk phone as well, but all continue to ring.

The experience with 3cx was great, along with the company that oversaw the upgrade once everything was in place and ready to go we switched off our analogue system overnight and removed desk phones the next day.

The 3cx software makes remote changes a breeze. The ability to allow end users access to a phone over their computer without a physical phone saves cost of a phyisical phone. Users have reported that it is easy to use both making and receiving calls and have noticed no quality loss from our old phone system. It is infinitly easier to administer than our old system and i would not go back under any circumstances, even at the cost of my employment.

The software has no cons, the only issues i have with any part of this are unrelated to the software just the servers hosting and in places were physical phones are installed.

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 . The admin panel is centralized ,which makes it easy for managers to properly oversee everything.

Configuring it when you are starting out takes a lot of time . Status changes ( from online to away and vice versa ) take a while to sync up and this could lead to missed call .

Even those without technical expertise can readily use the software's functions because of how user-friendly it is. The system provides numerous communication channels, including audio, video, and chat.

Infinite extensions and best mobile app. It is very easy to manage, CRM connectivity, Google and Microsoft integration, and more can be created with the 3CX Call flow Design app

It becomes slow if there's more people on the network using it at the same time, it disconnects and you end up thinking it's the person on the other side of the line who dropped your call but no, it actually disconnected on your side.

The interface is easy to you. It's useful to have a chat function too. Option of an app which is good when you're on the move

Relatively basic software, I'm not aware of many additional features. The interface, although easy to use, is quite basic looking. It could look slightly more modern.

First off, this software successfully allows for administrators to set up multiple incoming SIP trunks from one provider. Predecessors such as Trixbox and Asterix had trouble implementing this feature without extensive customization. If you are looking for multiple trunks, this is the software for you. Other options are the usual fare for a PBX - it's essentially everything users have come to expect from Trixbox or Asterix or other FreePBX software. The beauty is in the execution, though, as it takes almost no time to set up a system using this software.

Base licensing does not include some of the more advanced features that would set this apart from other software options. The need to pay for more trunks feels like a natural pay-gate, especially considering how much this feature is requested in DIY PBX communities.

Just had voice quality issue there and there, but it was on the settings and it was resolved.

During the first lock down when everyone was forced to work from work, we had 3CX Apps and making calls from home as if we are in the office. The App comes with the Instant Chat platform and Video Conference. It is cheaper to make phone calls from this system.

The Microsoft Teams integration hasn't really worked for me, thwy should fix the availability status sync - like when one is in a meeting.

This is a great piece of software when working from home. I connect to my VPN and I am able to make and receive international calls from the comfort of my home office.

Great for making international calls, from any location. I use this on my laptop and connect a bluetooth headset.

When I am using a bluetooth headset and listening to something (e.g music), if I start the 3CX app up it changes the way sounds comes out the headset. So each need to keep the app close and open it each time i want to make a call. A bit annoying.

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.

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

documentation can be outdated at times reporting is not the best

We used the 3CX softphone in our call Centre environments and it was a great solution, we used it to replace all our physical hard phones .

we did not experience any issues with the system so im happy to recommend it.
