Handy Second Number, but Calls Dropped and Random Holds
What do you like best about the product?
It was nice having a secondary way to use my cell phone, so I didn’t have to share my actual number.
What do you dislike about the product?
My calls kept dropping, or I would be put on hold at random.
What problems is the product solving and how is that benefiting you?
This issue was never resolved, so we ultimately ended up switching providers.
Easy Self-Hosting, Great Performance, and Fair Pricing
What do you like best about the product?
The fact you can self-host on a simple server, while retaining good performance, is a great feature. Easy to use, rich in features and fair pricing.
What do you dislike about the product?
There’s a noticeable lack of native AI features, and it feels like competitors are catching up quickly on that front. Integrations are also fairly limited, largely because there isn’t an open API.
What problems is the product solving and how is that benefiting you?
Possibility of calling locally colleagues thru their extension, calling phone numbers, but also doing video calls.

Seamless Cloud Communication with Easy Setup
What do you like best about the product?
I appreciate 3CX for transforming our old outdated phone system into a digital cloud-ready communication platform. It enables us to make and receive calls seamlessly from any location and device. I really like its unified controls for voice, chat, video, and messaging on a single pane of glass. Additionally, the initial setup was very easy as 3CX allowed us to retain our phone numbers and extensions. I also enjoy the integration with HubSpot for voice omnichannel.
What do you dislike about the product?
Lack of nice features such as voice transcriptions and AI integrations on lower subscription tiers
What problems is the product solving and how is that benefiting you?
3CX transformed our outdated phone system into a digital cloud communication platform, allowing seamless calls from any location and device.
Easy Setup, Flexible SIP Trunk Extensions, and Strong Business Messaging
What do you like best about the product?
Easy to set up and provision, provided that you complete the training certifications. It works on a bunch of different phones, such as Yealink and Fanvil, etc. The best part is being able to keep one phone number for your business while having multiple extensions under one SIP Trunk, with the flexibility to use the desktop app, the mobile app, or a hard phone depending on preference. The SMS-style messaging is also very good for communication within your business network. Overall, I find the platform fairly straightforward, and it can help companies save money while enhancing productivity.
What do you dislike about the product?
If you don’t have your hard phone user provisioned, it will show you as “Not Registered,” which can make it look like you don’t have the program. Once you have a proper user profile provisioned on a hard phone (depending on how your system is configured), you should be good to go. Also, I found the certification test to be tricky—you really have to pay close attention to how they present TRUE/FALSE and watch the wording carefully.
What problems is the product solving and how is that benefiting you?
It helps minimize the amount of back-and-forth email between different locations in our company. Instead of having to make phone calls or deal with long email chains, people can send instant messages, transfer calls, or bring others into a conference as needed. Overall, it cuts down on the logistical time it takes to get people together and communicate information.

Being able to get people on a bridge quickly.

Best-in-Class 3CX Phone System: Smart, Easy, and Reliable
What do you like best about the product?
3CX is the best phone system I have used in a long time. The up to date performance and intelligence is state of the art for 2026. Its easy to use and the support we are given if any issues arise is beyond helpful. This system has helped our agency to run more smoothly and never miss a clients call. The system integrates with our management system and the pricing is extremely reasonable.

We are currently not having any problems with 3CX
Comprehensive VoIP Solution, Slight Learning Curve
What do you like best about the product?
I use 3CX for office VoIP PBX and internal communications, and I really appreciate that it's compatible with multiple VoIP/SIP providers and iPhone manufacturers. The software client has a good UI and is easy to use and administer, which makes it very user-friendly. It allows us to route calls efficiently, both within the office and with field staff, without the need for costly IP phone units. Its ease of setup means there's a low learning curve, so getting new users and admins up to speed is quick.
What do you dislike about the product?
We do prefer the old UI to the new one. Some of the features in the old UI were better implemented, like backups, provider and IP phone templates, and on hold and holiday messaging. It would be an improvement from the administrator point of view to have the old UI methods brought back rather than the new script download and deployment methods currently favored.
What problems is the product solving and how is that benefiting you?
3CX routes our calls efficiently, supports multiple VoIP/SIP providers, and integrates with our existing equipment cost-effectively. We enjoy its user-friendly desktop and mobile clients, making it easy to deploy extensions without additional IP phones, and appreciate its low learning curve for quick adoption.
