Users from various organizations have found 3CX to be a reliable and flexible VoIP system that meets their communication needs. One such user implemented 3CX in their municipal offices, serving around 30 users. They appreciate that the software provides VoIP functionality across different operating systems, including Linux, Mac, and Windows, allowing them to seamlessly integrate it into their existing infrastructure. Another user, with a larger organization of 200 users, runs 3CX on a virtual server and Yealink phones, enabling them to explore unified communication options.

3CX is widely used as a VoIP solution in different settings. For instance, in call centers, call queues are utilized for efficient call handling. The system also supports features like ACD, auto attendant, and voicemail, enhancing landline needs. In an entire school district, 3CX Phone System is implemented to provide phones in each room for private conversations and convenient teacher-parent communication. The switch to 3CX resulted in significant cost savings for the district as they were able to remove the old intercom system.

Moreover, organizations of all sizes have adopted 3CX as a cost-effective alternative to legacy PBX solutions. With features such as toll-free numbers and the ability to manage phones across multiple locations and states, users find that 3CX simplifies phone management and offers flexibility. The software's setup process is straightforward and does not require new purchases since it involves reprogramming existing phones.

One highly praised aspect of 3CX is its mobile app which allows users to answer calls even when they are not in the office. Additionally, the system's intuitive and user-friendly interface, along with seamless integration between the desktop portal and mobile app, has received positive feedback from users.

While many users appreciate the functionality provided by 3CX, there have been reports of dissatisfaction with the customer service and support offered by the company. Nonetheless, overall user experiences highlight the value of 3CX as a flexible and reliable VoIP solution for organizations seeking to enhance their communication systems.

Easy-to-use Interface: Reviewers have consistently praised the user interface of 3CX, stating that it is easy to use and intuitive. Many users found the management interface easy to read and navigate, allowing them to quickly find what they needed. Some reviewers even mentioned that managing every phone and extension throughout their company was effortless with the 3CX interface.

Seamless Integration: The seamless integration offered by 3CX was highlighted as a valuable feature by multiple users. They appreciated the ease of integration with other systems, making it a seamless experience for their business operations. This capability allowed users to streamline their workflows and enhance productivity.

Flexible Configuration Options: Users were impressed with the flexibility offered by 3CX in configuring each extension and phone. Several reviewers mentioned the wide variety of options available, enabling them to tailor the system according to their specific needs. This flexibility empowered users to customize their communication setup for maximum efficiency.


  1. Lack of Stability in Windows Soft Client Interface: Some users have found that the stability of the Windows Soft Client Interface is not up to their expectations and believe there is room for improvement in terms of intuitiveness and reliability.
  2. Need for Improvement in User Interface on Mobile Client: According to user feedback, while the mobile client performs well in terms of voice quality and call answering on lock screen, it could benefit from enhancements to its user interface for a more seamless experience.
  3. Potential Points of Failure with SBC Requirement and Server Disconnection: Users have raised concerns about potential points of failure due to requirements such as having a Session Border Controller per location and the possibility of server disconnection, which may impact system reliability.

Based on user reviews, a common recommendation for 3CX is to choose the right edition and implement a fail-over solution. Users also advise comparing pricing to ensure cost-effectiveness. Seeking expert advice and training is highly recommended, including watching videos, speaking with experienced users, and partnering with integrators or authorized resellers knowledgeable in networking and VoIP. Taking these recommendations into consideration will help businesses make informed decisions when implementing 3CX for their telecommunication needs effectively. It is important to evaluate specific requirements and consider the expertise of partners before proceeding with 3CX.

3CX to the Rescue!

My entire school district uses the 3CX Phone System. It has allowed us to have a phone in each room, facilitating private conversations with a specific teacher, now the building or district office can not only talk privately with individual teachers, but teachers can also contact parents in a more convenient place and time. Switching to 3CX Phone System has also slashed the phone bill by two thirds. Anything that can save the school district some money is a great product, and that savings alone paid for the phones that were purchased for each classroom. It also allowed us to remove the intercom cables too, as it replaced our intercom old system as well.
  • The 3CX Phone System has a really nice auto-provision feature that works with plug and play phones, so then all that's needed is for each to have an extension assigned to them.
  • The 3CX Phone System web portal is exceptional. I love how I can keep it open during the day and quickly see who is busy on the phone and which lines are available. I can also call quickly by a simple click of the mouse.
  • The app that accompanies this allows me to provision my cellphone via the app to my classroom extension so that if I am out of my classroom and someone calls my phone, it also rings on my cell phone. I can also call via the app and it appears as if I am calling from my classroom extension.
  • The webmeeting function is clumsy compared to Zoom or Google Meets (Hangouts).
  • There is no support offered without paying for it, but the web forum that is offered for free does allow you to throw out questions and have them answered by someone in the community of 3CX user administrators.
The 3CX Phone System is perfectly suited for schools or businesses that want a reliable phone system and a reduced phone bill. It functions on traditional phones, the web, and on cell phones via the app, making it flexible enough to suit today's business or educational institution needs. The installation can be done with some basic knowledge also, without needing to hire anyone or pay 3CX for assistance.
  • The money we save by switching to 3CX has helps us in other areas of our district's budget that directly impacts students.
  • After setting up the system, if we need to add another phone, it is super easy and takes about 5 minutes. Just plug in the phone, assign it an extension, and start using it.
  • Staff training was very minimal. Users can bypass the web portal and just use it via a traditional phone.
The 3CX Phone System is only a five because while they provide set-up/how-to/Q and A documents to help your district or company get started, they do not offer support for free. The documents provided, though, are good enough for you to get you up and running. We also found a good source of help through a sip trunk provider, which was a 3CX reseller provider.

We replaced our old office phone system (Cisco Call Manager) with a cloud-based 3CX platform across our organization. Our office location was moved to a new building so it was the perfect time to replace it. As we also moved to a cloud-first strategy, we opted for a hosted 3CX platform. Although it as more features than the old system, I am afraid only the basic features are mostly used.
  • Call quality is good, better than our old system. Though technology-wise you can't compare, quality is better than I expected.
  • Having softphone and mobile apps available is a good feature.
  • Configuration for the user is relatively easy.
  • Mobile app is a bit dull to look at. Could be more modern looking
  • Softphone functionalty is ok, but not great
A good replacement for your basic phone system. If you like mobile apps and softphone, this is also a system to have a very good look at. 3CX is a good competitor in the field but I strongly suggest to compare all the options. If you replace a legacy system you should inform your users of all the new features a system like 3CX offers.
  • With the right call routing configuration the costs can come down
  • Having the mobile app makes employees better reachable.
We didn't want Cisco Call Manager anymore. We used a very old version previously, but nonetheless it didn't have a very good name in the company. PureCloud was too call center focused so in the end, we like 3CX best. A small pilot was configured very fast, and after we went full production, there were no big issues.
I didn't have to use support personally but I have talked to the administrators of the system and they confirm that any issue is dealt with quickly. As we haven't had big issues I can't talk about priority 1 incidents which require immediate attention, but normal issues are answered fairly quickly and accurately.
