3CX Reviews

Summary: Overall good experience for both users and admins.
Lots of good features compared with the competition.

Positive: Easy to manage.
Lot's of administrative tasks are automated like renewing SSL certs.
Flexible for most businesses.

Negative: STUN provisioning can be tricky but they recommend using their SBC (Session border controller).

Summary: We have be a partner for several years and exclusively use 3CX for our installations. It is very flexible and capable.

Positive: Scalable and very capable. We have small installs with 2 -4 users all the way up to 100+. Simple to setup and maintain.

Negative: Some software upgrades are more challenging than others.

Summary: Turnkey system that you can get running in a matter of minutes and will stay running for years without fault.

Positive: 3CX is simple to setup and provision phones. In-built call queues are a snap to setup. Wide range of supported phones.
ROCK solid - always on and just works.

Negative: Wish it had some more customizability like Asterisk. But not a showstopper.
Comes with some features that are poorly trying to compete in a crowded marketplace - i.e. video conference and conference bridges are lacking compared to like features you probably already use with products rhyming with "reems" or "loom".

Summary: A solid product for those looking for an inexpensive but scalable PBX solution that you can spin up easily locally or in the cloud.

Positive: Customizable and scalable at a very reasonable cost. Easy to deploy on a nearly any type of hardware.

Negative: SBC's required when hosted in the cloud (versus NatPass equivalent); no multi-factor authentication support.

Summary: We have had a wonderful experience with 3CX and have migrated over 20 customers to the platform in our private datacenter.

Positive: Incredibly easy to deploy on-site, very easy to configure and a lot of advanced call flow features that allow for the ability to support any customer.

Negative: No outbound fax integration, no option for monthly payments.

Summary: Overall 3CX is a great software, but I'm not a HUGE fan of the company. Not speaking from an end-user standpoint, but from a partner stand-point. End-user point of view: It's easy to use, you don't HAVE to use the web interface but you can and it works well.

Positive: The software is easy to use, and very configurable. With the enterprise license you can do what you need to do with the phones to make it nice and customized.

Negative: Company changes pricing fairly often since v16
"Free" tier is basically being phased out.

Summary: Overall I would recommend 3CX to any customer and MSP that is looking to offer a feature rich, reliable communications platform to their customers.

Positive: It works and works well.
I can count on 3cx to provide my customer reliable communications. The software is easy to use, has lots of features and allows for the flexibility that businesses need in today's work environment.

Negative: Updates often happen without notice, especially if you are hosting with 3CX. Documentation follows, but after the update has been done, which can make for a frustrating support situation....prime example of V18 release 5 to release 6. If you are hosting in your own environment, you have more control.

Summary: Overall is good. I have very few complaints. More positives than negatives and the pricing are just the best thing there is.

Positive: Easy to setup and use.
Easy to integrate with some third parties like Office 365.
Easy for building call flows.
Allows use of API calls when programming call flows to integrate into other apps.
Great Price.

Negative: Support to some phones has been removed.
SMS new settings are not as flexible as the old ones.
You need a Phone router (Specific phones have it) or a computer to use as SBC to connect the phones to the server. Unless installing 3CX in an on-prem server.
The mobile app keeps unregistering after some time.

Summary: Product works great, but I had to use my own ingenuity to solve issues. Early upgrades used to break one or two settings every time. I would delay upgrades till everything settled down. That has stabilized. But lately I've had some security breaches. 3CX seems deaf to security flaws.

Positive: Easy to install.
Easy to configure.
Works well.
Backs-up well.

Negative: No free support even when the problem is 3CX's fault.
3CX doesn't take security flaws seriously. When confronted, they try to sell their Hosting service as a fix-all.
