Great System

  • Review provided by G2

What do you like best about the product?
The flexibility of the system is amazing. Tons of options and routing features.
What do you dislike about the product?
Updates can be a pain. I like to stay up to date and get the best feature, but the updates from version to version (not dot releases) can be time consuming.
What problems is the product solving and how is that benefiting you?
Phone call routing is the biggest. Voicemail to email is super helpful.

Good PBX and support

  • April 09, 2020
  • Review provided by G2

What do you like best about the product?
I like the ability to manage the PBX myself.
What do you dislike about the product?
I dislike that 3cx updates the conference site without providing feedback or a heads up.
What problems is the product solving and how is that benefiting you?
Immediate addition of extensions, as needed. Realized cost savings after transitioning to 3cx.
Recommendations to others considering the product:
Easy to use and manage. Ease of use is much better than Iwatsu

Easy to setup -- Easy to use.

  • April 09, 2020
  • Review provided by G2

What do you like best about the product?
The 3CX Administration panel has stayed consistent throughout version 9 all the way to its latest release, 16. With that said, its always been easy to find extensions, customize inbound/outbound rules, setup DID's/trunks and work with ring groups. This is by far my favorite things about the system. If I had to rank a 2nd item, the phone firmware and templates that we use is always updating, which allows for easy to push/provision firmware/config updates to the phones on my LAN. Configuring a new phone is also quite easy to use.
What do you dislike about the product?
For multiple sites where I'm hosting, I wish I had the ability to configure one central panel where I could break the extension into multiple groups, all while administrating under the single pane of glass. Configuring STUN for remote employees, especially while we've been in COVID-19 lockdown, has been been a challenge.
What problems is the product solving and how is that benefiting you?
Because how easy 3CX server is to administrate I'm able to setup new phones, configure existing extension and use modern features like web client across my company. The benefits are hosting 3CX in all of my sites, means all I have to pay for is maintenance and no hosting fees. It runs on a 2 core, 8 GB VM, which is pretty lightweight for an office under 30 people. 4 Cores, 16 GB should be suitable for 100 people. In short, its very lightweight for the amount of simultaneous calls that can occur.
Recommendations to others considering the product:
If they are struggling with other VOIP software out there, I think others would find 3CX easy to use administration and overall use of phones connected through it to be. Its much more affordable than some of the big boys out there.

More than we asked for!

What do you like best about the product?
The web interface. It allows us to easily setup up phones and administer the phone system.
What do you dislike about the product?
Not much of a dislike, but wish you didn't have to get the Call Center edition to get more than 16 calls.
What problems is the product solving and how is that benefiting you?
3CX replaced our old PBX system that was end of life and end of extensions. No more having the PBX guy come out and configure a phone. It so nice just to pick up the phone and move to a new location.

Having the 3CX app on my cell phone allows me to be out of the office and still "be in the office" as far as callers know.

The web conferencing feature has really improved.

Greatest VoiP Phone System Ever

  • April 09, 2020
  • Review provided by G2

What do you like best about the product?
Whats not to like. Easy phone provisioning, supports a wide range of phones, Constantly improving it, apps for both iphone and android, webmeeting w/video support, remote control of other user computer systems for tech support and the list goes on and on.
What do you dislike about the product?
Needs more sip trunk documentation for non certified providers like ATT. I know I said non certified but lets be real sometimes you have to use such because some businesses might under contract and will need to use the service until their contract expires i.e. Att Sip Trunks
What problems is the product solving and how is that benefiting you?
With Covid -19 over half of our office had to start working from home with out any prior warning, Was able to have them up and running with a full feature phone setup including video conferencing within one day. Its like they are still in the office and the ability to collaborate on day to day issues has been great.

3CX - The I.T. Managers Phone System

  • April 09, 2020
  • Review provided by G2

What do you like best about the product?
Its very intuitive for both technical and non technical. I like the vast amount of hardware that can link up to it. My Reseller and Support company are TOP NOTCH. Obviously why they chose 3CX.
What do you dislike about the product?
Nothing that I can think of. I wish I would have moved my current company to this right after I started.
What problems is the product solving and how is that benefiting you?
The BIGGEST benefit I have found is the mobile app. In the days of "Shelter in Place" and work from home, the mobile app has proven it worth millions of times over. I could guide my staff to download it and sync it up with ease. From there its like they are at the office.
Recommendations to others considering the product:
Forget any other thoughts of phone systems 3CX is the way to go hands down.

A great system all around

  • April 09, 2020
  • Review provided by G2

What do you like best about the product?
I like the ease of installation and implementation of 3CX, Coming from a hosted VoIP from AT&T I am relived at how customizable this system is and being able to perform my own troubleshooting. Everything about 3CX is great. The team at the office like how versatile the system and how easily it adapted to the current remote working situation. The VDNA system we had would have never been this flexible.
What do you dislike about the product?
A few features I wish were easier to adjust like call waiting notices and some minor issues.
What problems is the product solving and how is that benefiting you?
The COVID-19 situation I am so happy we went with 3CX. This has made getting calls to people remotely so much easier and pain free.
Recommendations to others considering the product:
Great VoIP phone system I highly recommend

Powerful and Robust

  • April 09, 2020
  • Review provided by G2

What do you like best about the product?
3CX is one of the most powerful, robust phone systems I have ever had the pleasure to deploy on a wide scale enterprise environment.
What do you dislike about the product?
There is a lot of arbitrariness. For example, there can be no spaces in user passwords and the encryption passphrase for backups cannot have special characters and a max of 32 characters.
What problems is the product solving and how is that benefiting you?
We can use DAC adapters to have door control, alarm systems, etc. It's also very useful that we can use skill-based routing in our ring groups to have the next caller be connected to the representative with the least total calls for the day.
Recommendations to others considering the product:
Get phones that work natively with 3CX under "Local LAN" setting. Fanvil phones are a good consideration.

Using 3CX for 10 Years

  • April 09, 2020
  • Review provided by G2

What do you like best about the product?
- I like the usability of the system
- stability of the pbx interface and back-end
- wide OS and devices support as servers or phone client
- Constant updates and improvements almost non stop
- Security always top priority for 3cx
What do you dislike about the product?
- What I want to see or to have SMS/MMS feature from SIP trunks support SMS , I think it will be available during 2020 accroding one of emails I received from 3cx.
What problems is the product solving and how is that benefiting you?
- I have a partnership as 3cx and already many of my clients using 3cx, some of my clients is very sensitive business in terms of depending on phone systems.
Recommendations to others considering the product:
you can use 3cx free of charge on the cloud - just try it nothing to lose to try.

Easy and Effecient

  • April 09, 2020
  • Review provided by G2

What do you like best about the product?
The setup of a 3cx system is really simple and very efficient when it comes to a managing aspect. If you are running on a Linux environment updating is the easiest I have seen. Support is also very helpful. And there is a huge community that is willing to help. The variety of phones that will work with a 3CX system is vast.
What do you dislike about the product?
Licensing, I wish they would allow all options on one license.
What problems is the product solving and how is that benefiting you?
Right now working remote is the biggest problem and having a 3CX PBX at our customers sites help with that. They can either install the applications on their workstations at home or use the mobile app on their cell phones and still conduct business.
Recommendations to others considering the product:
3CX is very easy to manage and that is the main goal when looking at any business related application.
