Overall Satisfaction with 3CX Phone System

We use 3CX to manage phones through our entire company across many locations and multiple states. All phones are able to be managed by a single 3CX controller, which simplifies management and support while offering features and flexibility to users. Many users have a traditional desk phone, some use only the 3CX smartphone app, others use both. Each extension can be used with any of these options.


  • Simplicity: Using a single 3CX interface we can manage every phone and extension used throughout our company.
  • Flexibility: There are a wide variety of options to configure each extension and phone. Changing anything after the hardware is deployed is very easy.
  • Portability: Phones with 3CX can be easily moved or repurposed within an office or at remote locations, including users' homes. The mobile app allows users to use their office extension anywhere without exposing their cell number.


  • Experience or support required: SIP is complicated and nuanced by nature, with any phone system. If you don't have experience with this, support from a local integrator is all but required.
  • Adding call flow apps is very complicated: 3CX can be extended with custom developed call flow apps, which is great to meet a specific business need. However, this is very complicated by its nature and requires custom software to be developed.
  • Failover somewhat limited: Setting up failover is relatively complicated and somewhat limited in performance.
  • Much lower cost than other PBX options: Our company paid nearly 1/5 the cost of purchasing a hardware-based PBX when we instead switched to 3CX. In either case we would have had to replace all phone hardware, but with 3CX we saved a ton of money on licensing and server hardware.
  • Many locations, one phone system: We were able to tie all of our locations into a single 3CX phone system. This means each location is an extension, allowing call transferring, increased flexibility in auto attendant, and simpler numbers to remember.
  • Elimination of carrier service: With 3CX we were able to replace carrier service at many separate locations with SIP service. This reduced each locations' phone bill from $50 per month to $5 per month.
Other phone systems we evaluated were more traditional PBX systems using proprietary hardware servers. We chose 3CX for the flexibility and self-service capabilities. For us this meant being able to replace an aging phone system in one move, then bringing remote locations into that new phone system in separate moves. On a day to day basis, we can easily handle questions and changes that come up without being SIP or phone system experts. As our business evolves, we are able to scale our 3CX system without worrying about hardware limitations or expensive expansions.

I would strongly recommend the 3CX phone platform over any hardware based PBX system. 3CX scales very smoothly since it can be run on anything from a pretty basic computer to a powerful server to a cloud VM. This means getting started can be very inexpensive, and migrating can be much lower cost than moving to a hardware PBX. As with any phone system, experience or support is needed, but 3CX is well designed for usability. There is a decently sized community with users who can help out and share ideas.
