Project manager

The only drawback I noticed the phone calls quality on the app is not up to mark and sometimes drops.

AG Director Arts and Craft Department

CX is a single interface for customer live chat, call logging, queue management and real-time reporting.

Business Owner

Unlike other VoIP / SIP based systems, to connect physical phones to 3CX you need to either have one of their phones that acts as an SBC or you need to set up an SBC in a small Linux VM.

Payroll Manager Tax Preparer

It works very well for our company which has 2 offices about an hour apart from each other.

Web developer

I use the self-hosted version with a cheap VPS and pay less than £5 a month including calls on my landline.

Accounts Administrator

I think call log information could be in a clearer format.

Tech

Not that much at all. If I had to say something I would say the licencing should maybe have more options for smaller business deployments.

IT Support Supervisor

I use 3CX via the desktop app, ios app and a voip handset.

The latest update - version 20 has removed some features such as granular reports.

lead

We are in contact with our backup office in other countries.

HR Manager

I wish there was a text feature beyond texting only people who have the 3cx app.

Features that were well-established in previous versions were either reduced or completely removed, leaving users with less than a quarter of the configuration options they were accustomed to.

Our IT team could choose to host internally or on cloud or have 3CX host it - we like the flexibility that offered.

I have just started using it but finding it difficult to dial the number as despite adding zero or + before the number, it still says invalid.

Director of Business Development

Contacts does not always save changes you make on contacts.

The user interface has been redesigned which is not as polished as the previous version.

The online platform should have more user settings.

Medical Coder

There was some confusion with voicemail setup and I found the help menu to be lacking, but once I got the hang of it I really enjoy the ease and simplicity of this product.

CX is a feature full VoIP PBX for small, medium, and enterprise businesses.

Application Specialist

We use it for all internal communication that needs to be done over the phone and it enables us to get in contact with our stores to address issues without any fault.

Can monitor messages via emailed transcripts from multiple phones.

Inability to easily choose which number you will call from.

Systems Engineer

We seem to have lots of issues with it with just making/receiving calls and that’s a simple, important thing for phone software.

Help Desk Manager

Our calls dont drop, we dont have any issues with the call flow it just works.
