Simple UI, admin friendly, but surprisingly robust system

  • November 12, 2022
  • Review verified by G2

What do you like best about the product?
In contrast to phone systems of the past like Cisco UCM, 3cx presents you with such a simple admin interface it seems laughable at first. When you dig into the different features you find that it does have every feature you need and all that you want but delivered in a logical and straightforward way that allows you to become an expert in hours rather than phone systems of the past which required months of study and hands on experience to become moderately skilled in navigating labyrinthian menus ambiguously named groups and lists. Once I had used 3cx I could never return to UCM other dilapidated systems again. And the most incredible thing is by comparison 3cx is dirt cheap and can often make use of existing VOIP phones or install the 3cx app instead and throw hardware out the window. Call quality is pristine and call routing is a dream. Host in the cloud or on-prem or both and have no deficit in call quality. Any issues I've seen were solved with a couple slight tweaks to the call settings.
What do you dislike about the product?
Faxing is an issue. They are making small strides on working reasonably well with an existing line but plan to switch to a cloud service if you have multiple fax lines and save yourself a headache. This is the only area 3cx lags behind competitors like Ring Central.
What problems is the product solving and how is that benefiting you?
The simple call center features have enabled customers business units to operate at nearly double the efficiency and with a small fraction of the admin overhead.

3CX is a complete phone system

  • October 10, 2022
  • Review verified by G2

What do you like best about the product?
What i like best about 3CX is the great versatility. Depending on the version you'll choose (Standard, Pro, Enterprise), you'll have at your disposal a great set of features. A great feature is Voice Designer: you can graphically build your phone system.
What do you dislike about the product?
There are no really downsides using 3CX. Maybe 3CX could reduce its ticket costs. When you need support, you can count on a great online community. So, no really downsides.
What problems is the product solving and how is that benefiting you?
If you need a complete phone system, 3CX is your choice. You can do complex phone structures, even with thousands of users and multiple tenants. Source: myself as a 3CX Advanced Engineer.

3CX: Sweet and Simple

  • October 10, 2022
  • Review verified by G2

What do you like best about the product?
3cx has many benefits. The administrative interface is user-friendly, as is the end-user interface. Phone (both soft and physical) are easy setups. User creation and management is kept basic, but can get very granular when needed.
What do you dislike about the product?
There isn't much that I do not like about 3cx. The fact that the desktop Windows app is no longer supported is a bit of a bummer. The web app doesn't seem the have the sleep user interface like the desktop app did.
What problems is the product solving and how is that benefiting you?
For a remote work enviroment for my team, it is important to have light weight tools that are easy and effective. We have had little to no issues with the 3cx softphone app and call transfers are painless.

Super easy to deploy, super easy to use.....

  • October 05, 2022
  • Review verified by G2

What do you like best about the product?
Overall it's a fantastic product, it's easy to deploy and easy to use for end-users. The app is great too.
What do you dislike about the product?
There isn't a lot to dislike with the product, the physical phone integration with the system isn't great (i.e. phonebook sync and phone features such as forwarding) but I supposed that's the nature of SIP/VoIP.
What problems is the product solving and how is that benefiting you?
Since the pandemic hit working remotely is such a huge consideration, 3CX allows users to work from anywhere as it has the flexibility of physical phones, web app, desktop app and mobile apps.

3cX phone system, What can't it do?

  • January 18, 2022
  • Review verified by G2

What do you like best about the product?
We have an on prem. version of 3cX. it is so versatile. Everyone can use it from where ever they are. So long as you can see the internet some how, via home wifi, 4G/5G phone or cabled network in you office/home you can use 3cX to make a call or video conference be it one to one or in a group. You can use your laptop or you mobile or even a handset. all of which are simple to configure and use.
What do you dislike about the product?
They will insist on charging us for the licence! I really can't find a thing I don't like, its as near to perfect as it can get for us.
What problems is the product solving and how is that benefiting you?
We have 5 offices across 2 sister companies and had 3 different phone systems so internal coms. was an issue. Now we have 5 offices and 1 phone system joined in some cases with VPN and others with out. All are now able to make an internal call between each office for free! our costs are 50 times less, yes really. no more ISDN or PST lines, nothing but sip trunks over standard FTTC or 4G internet.

More recently we are all home working due to the Covid 19 Virus. Now we have 45 different office and the phone system still keeps us in touch. Still can make a call internally for free still looks like we are in the office when we call out. All done with the 3cX app on PC's, Mac's and mobile phones (both Android and iPhone) via Good old home wifi.
Recommendations to others considering the product:
Try it out for free and when you have used it for just a few days buy it, it's great. No more phone lines not more ISDN just any form of internet provision be it, leased lines or FTTC cable provided or 4G and SIP trunks just brilliant. can be used in and out of the office can be hosted in the cloud or on prem. can have home users. can run just 2 people in a startup business but also is scalable enough to run large call centres or hotels or multinational multi-sited businesses. Works with Mac's, PC's, mobile phones both android and iPhone can be hosted on a Windows Linux either on tin or on a VM.

Best phone system I have used.

  • December 02, 2021
  • Review verified by G2

What do you like best about the product?
My favorite part is we have the ability to take calls on the go seamlessly. The quality of the calls do not change either when using our 3CX apps. Our clients wouldn't know if we are at our desk or on the move.
What do you dislike about the product?
I wish we could search on the web 3CX by phone number. There might be a way that I am unaware of, but when we search the number and hit enter, it dials the number.
What problems is the product solving and how is that benefiting you?
We are able to communicate with colleagues, clients and carriers remotely while working from home or on the go. It also allows us to have more control over the phone system, extensions, switchboard, voicemails etc.

Ease with 3CX

  • November 24, 2021
  • Review provided by G2

What do you like best about the product?
I can listen to call recordings accurately and with ease
What do you dislike about the product?
Sometimes numbers take a bit of time to show on the desktop extension if I have used the app to make a call.
What problems is the product solving and how is that benefiting you?
I am using 3CX to improve the quality of calls made by my colleagues and me. I have realized that 3CX helps us listen to our calls and use those records to improve the service offered to our customers.
Recommendations to others considering the product:
It would be nice if the calls done via the app would reflect on the web extension a bit faster than usual and vice versa
