Full featured Hosted SIP VOIP solution
Comments: Our on premise system had a number of issues. As it was not hosted it would only work in the office. Sometimes when we had an outage random users would lose their voicemail greetings. There was missing call queue and forwarding functionality that we required.
Pros:
Easy to implement. We converted over from our on premise Avaya system in less than an hour with little more than a couple of forms and spreadsheets to fill in. We have the option of the computer soft phone or the iOS app which means that people can decide how they receive/make "landline" calls. For thos in shared/high noise locations there are a number of voip deskphones that will also work. It gave us much better queue/forwarding functionality than we had before. Before this system any call forwarded to a mobile/another extension had the number of the extension doing the forward rather than the initial caller. Simple admin interface. Easy to use.
Cons:
There is no way to seperate the softphone volume from the generic computer volume so it can be quite a shock if you are doing something and the phone rings. There can also be annoying instances of the app trying to call on any number that you click on as it cannot identify phone neumbers. Minor things but room for improvement.
Alternatives Considered: RingCentral MVP
Reasons for Choosing 3CX: Mainly i wanted to switch to a hosted solution with an app. We had dozens of users with $500+ deskphones literally gathering dust. So i wanted the numbers but not the hardware. I also wanted it for people who are travelling or did not have a company mobile phone so that they could send and receive calls without using their own plan.
Switched From: Avaya Cloud Office
Reasons for Switching to 3CX: It was a contractual obligation. When moving from my old system i still had a contract with my SIP phone so 3cx was the most cost effective option.

Hi Robert and thank you so much for taking the time to leave us a very good review. We hope you continue to have a good experience with 3CX. In regards to the cons you mention, if you have multiple speaker devices (computer, headset, monitor) you can select an individual device and set the ringer to be that and adjust the volume accordingly. If you wish, you can also exempt certain websites from having the numbers detected as telephone numbers, from the settings of the 3CX click-to-call extension.

3CX is fine, but it is all about who handles the hosting
Comments: 3CX feels like it is a step up from a normal landline, but I don't see any wow factors that I feel like I could get from some of the other VoIP names. If you're looking for something less expensive than Ring Central, Phone.com, and OnSip, then you should be able to find a small VoIP provider willing to offer you a hosted package with 3CX for a lower price.
Pros:
3CX is straightforward. It seems to have all the necessary features for a small business. Still, as a business owner who cannot work on the admin side, I can only comment on the usability and stability. Compared to other softphone apps, I've never had significant issues. I use 3CX as a softphone on an iPhone, through a Yealink desk phone, via Chrome plugin, and on an iPad. Surprisingly, the limitations I see are not due to the daily functions. There are some features I would like, but there is nothing about this app that hinders my company's ability to operate without delay. We have users in China, Thailand, the Philippines, Jamacia, Venezuela, and the US. All locations work well, and the apps work even with limited internet access. There are times when the connection is not great, but this is usually due to the internet and not the apps.
Cons:
There is no way for my ringer on my softphone or desk phone to be customized to ring differently when someone calls my extension vs. ring group. I wish there were connectivity with Zapier so that I could push contacts from other services into our address book. It would be nice if the SMS chat feature worked more similarly to a shared inbox, where everyone could see it. You can only transfer the chat to another extension, which makes SMS hard to use as a group. Overall, the cons are not about the ability to use 3CX but the features I wish it had that could provide a better overall experience.

Hi Sam and thank you for your review! We are glad to hear that you are enjoying using our software and that it has helped you stay in touch with your employees throughout the world! Regarding the points you raised, desk phones can be configured to have distinctive ringtones for Queue Calls, so you should certainly consider switching to using Queues instead of Ring Groups. Apart from this, you would also get better reporting capabilities and a lot more polling strategies to choose from. For syncing you phonebook contacts, we do currently offer integration with Microsoft 365, but in the coming updates we will have a REST API that may also allow you to interact with the 3CX Phonebook, giving you the maximum flexibility in syncing your contacts between various platforms. Incoming SMS messages can be sent either to an Individual Extension or to a Queue, in which case all logged in members of that Queue will see incoming messages.
great phone system for remote team
Pros:
works great to ensure we can stay away from call center features and have remote agents log in and control call flows. Covers most of our needs in digital phone service management for our clients
Cons:
some agents would see occasional status change, need to address connectivity issues sometimes, but overall works great. Would love to have an option to add to the same call more than 2 numbers.

3CX - Don't Waste Your Time or Money
Comments: I've used 3CX for more than four years, and in that time, it hasn't grown on me one bit.
Pros:
We can use it to answer and transfer phone calls that come into the call center.
Cons:
Where to start. It's clunky and not user-friendly. Terminology is confusing and not for lay-people. It's web-based, so any blip in our internet causes 3CX to freeze and/or die for our agents; it also causes a delay during calls, so that people end up talking over one another.
A Perfect Phone System
Comments: The Overall experience with 3CX has been very Good. Before 3CX we used Asterisk. Though Asterisk does good work, what it lacked was a proper telephone system useful for Businesses.
Pros:
3CX is a perfect Phone system for Businesses. It is one of the best product in the market when it comes to SIP and VOIP Telephone Systems
Cons:
3CX has worked perfectly for me so far so it is difficult for me to list down what I like least about it.

Hello! Thank you very much for your comprehensive and positive feedback! We are glad to hear that 3CX has effectively addressed your communication challenges, positively impacting your business. We completely agree with your assessment that 3CX is fully scalable, making it the ideal solution for connecting teams, customers, and remote workers as your business continues to grow.
3cX for your call center and VoIP needs
Comments: Overall, I have no complaints on 3CX as we are very satisfied.
Pros:
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.
Cons:
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.
Alternatives Considered: VICIdial and VitalPBX
Reasons for Choosing 3CX: Freepbx for me is very hassle to setup as it is asterisk based and Dialfire is very laggy on our side.
Switched From: Dialfire
Reasons for Switching to 3CX: VitalPBX is much more expensive on our current setup and we are not comfortable on using Asterisk based system yet. Also vicidial, it's a great software yet we don't really like the design of the app as it looks outdated.

Hi Cliff and thank you so much for taking the time to review 3CX! We are so glad to hear that you love the ease of setting up 3CX and all the great features offered!

The most easily managed telephone systems
Comments: We have switched to 3CX as an organization for several months now and we are very satisfied. Before the transition, we used open source applications and it took a lot of effort. Setting up and using 3CX was very easy and hassle-free. The best part is that it supports all vendors. Establishing links with other branches or exits and redirects is very simple. Compared to other telephone systems, the prices are very affordable. The part I like the most is the mobile application. So, if you are not near your desk phone, you can easily manage the calls, even you can manage the calls from abroad. Another advantage is video conferencing, which frees you from the licensing and financial costs required for other video conferencing solutions.
Pros:
I think it's great to have software, because if you have an office in a remote location and an employee works there, you need to set up communications and buy the necessary equipment for them to use the internal phone, that's what it takes. a lot of foreign funds. However, through the application, the employee uses his computer or smartphone.
Cons:
Sometimes, when a new user is added, the phone book of some phones is updated late. This will take 15-20 minutes of your time
Alternatives Considered: Aircall
Reasons for Switching to 3CX: It was very easy to set up and manage. Considering both the features and the price, we decided that 3CX is the best choice.
Best Value for VoIP and Web Conferencing
Pros:
It was inexpensive, there are local experts, easy to setup, and their new features continue to improve an already great platform
Cons:
It's less known so it can be confusing to employees or external participant
Alternatives Considered: Cisco Unified Communications Manager
Reasons for Choosing 3CX: We were using an old traditional phone system and needed to upgrade to a VoIP system.
Reasons for Switching to 3CX: initially we chose 3CX because of the price and local experts.

3CX - The only way to manage voice calls
Comments: I'm never using a traditional VOIP desktop phone or mobile after using 3CX. This application works incredibly well regardless of how you use it. It's incredibly consistent and reliable; an outstanding product for fast-paced workplaces.
Pros:
Functionality and ease of use from the user end, and the robustness of the management console from the administrator's end.
Cons:
Sometimes an account/users can be removed or signed out of a service. The fix is simple and easy once you know how to do it.
Revieuw of an easy to use and setup a 3cx system
Comments: Overall a very powerful tool that gets the job done
Pros:
The enormous possibilities to route , manage, create a calling que and configure multiple in and out.
Cons:
Some rule builder is missing in the setup of setting up and configure

Hello Raoul! Thank you for your review on 3CX! For any issues you may face, you can reach out to our Customer Service team for assistance via the Live Chat bubble on www.3cx.com or by email at [email protected]
We stopped wasting money on LANDLINES and chose 3CX as out internet phone PBX
Comments: For years we had 4 dedicated ATT land lines coming into the office. Most of the employees had 3-4 line phone on their desks, and we would have a few wireless handsets available dispersed in the building. At the time a fully enabled PBX system was simply not justifiable financially. The 3CX software based PBX system changed all this. With a single IP based SIP, we are able to hold up to 16 simultaneous calls! It also piggy backs on the TCPIP network, so when moving to the new office, we did not have to run and install a single phone rj45 jack. Within the day, every employee had a dedicated extension assigned that can be linked to their mobile phone (if they want) . We also created RING GROUPS allowing to dial an extension like 72535 (SALES) which would ring all the sales staff. Everyone liked the ease of picking up others calls, transferring calls, transferring to voice mail and more. You can also load an app to your IPHONE or ANDROID for 3CX. As long as you have DATA services or WIFI, your extension is fully functional anywhere you travel worldwide.
Pros:
Price, Ease of set up and feature rich capabilities. The price can be FREE if you are a small office. Still, even for a larger organization the pricing is extremely affordable. It took less than 90 minutes from download to our complete office set up, including 15 extensions. All this with zero training, just following intuitive user interfaces.
Cons:
The support is not great. While we can easily google and search through the 3cx portals, we did not feel there is adequate technical support readily available.

Thank you for your positive feedback. With regards to support. Support is offered via your reseller. If the reseller is not available, we can assign a new one, by emailing [email protected]. If you would like to purchase a support ticket directly from us, it costs $75 a ticket and can be bought from the customer portal www.login.3cx.com
Finally found something we can rely on.
Pros:
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.
Cons:
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
3CX Phone for Windows - EndUser review
Comments: 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.
New to VoIP
Comments: 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.
Pros:
The software is very affordable compared to other products we looked into and provides an array of options - almost anything we'd need.
Cons:
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.

Hi Teresa and thank you so much for taking the time to review 3CX. We are so glad to hear that 3CX has provided you with all the features you needed for your business and helped you save at the same time! Voicemail notifications are synced between the devices. Missed call notifications are synced between 3CX apps which are directly connected to 3CX via HTTPS. IP Phone missed call lists can only be reset from the devices themselves. Declining a call will only decline the call for the device itself as each device will receive its own INVITE message to establish a call and declining will only decline that leg of the call. Hope this helps clarify any confusion around the synchronization.
VOIP and Soft Phones
Comments: 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.
Pros:
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.
Cons:
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.

Getting in Touch with Fellow Colleagues and Clients
Comments: 3CX is used on both phones and pc which means a user can have it on the move or in a specific working area. The software has a lot features in one place that assist in communication.
Pros:
The software is good with organizations. I use it in the organization making outbound and taking inbound calls from both clients and colleagues. 3CX also has features like call transfers and call conferencing enables a link between different parties.
Cons:
As any other software there are some issues. The system crashes sometimes and communication is cut affecting the organization. The system cannot work with just any kind of internet connection the software will not work properly.

Low-Cost Phone System
Comments: 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.
Pros:
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
Cons:
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.

Simple and easy to use
Pros:
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
Cons:
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.

Thank you for sharing your positive feedback about 3CX. We're thrilled to hear that you find 3CX's interface easy to use, with the added benefit of a chat function, and appreciate the convenience of our app when you're on the move. We also appreciate your feedback about the perceived simplicity of our software and interface. Our team is always working to improve and add new features to our system, and we'll take your feedback into consideration as we continue to make updates.

Easy to use, no hassle PBX system with enterprise reliability and small-business ease of use.
Pros:
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.
Cons:
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.
All in one place!
Comments: All in all a great program to utilize features that phones have. Other switchboards in the past that I have used had very little functionality and not the useful features that 3CX has.
Pros:
-Everything about your phone communication is in one place. You can do web meetings, check your voicemail, see who all is on the phone or away at lunch. You can organize your day with your coworkers. -It's on apps that you can put on your phone if you can be at your desk or if you can't take 20 minutes trying to figure out how to forward your calls to your cell on the phone itself.
Cons:
-You have to know what clicking on certain things mean. In other words, don't accidentally click on a coworker's box if you do not mean to call them. I have been there a few times.

3CX Soft Phone
Comments: 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.
Pros:
Great for making international calls, from any location. I use this on my laptop and connect a bluetooth headset.
Cons:
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.
3CX Response
4 years ago
Thank you for your comments about our software! About the issue you faced with the headset, our software does not directly affect the headsets, rather it registers to the sound devices the OS is using. Having said this, I would suggest checking the OS sound settings, and also maybe try another headset if you have one available, maybe a wired one to rule out this being somehow related to BT.

Adaptable and Progresive
Comments: 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
3CX Softphone great solution for our call centre.
Pros:
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 .
Cons:

Pros:

Thank you for the review. With the upcoming 3CX iOS App (18.0.2) release, the minimum iOS version supported by 3CX will be iOS 14. This is to ensure a more modern, stable, and reliable experience for all our iOS users.
Great and easy to use
Comments: 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!
