Anno 2024, IP (Internet Protocol) telephony appears to be at cruising speed. Organizations have switched en masse from antiquated digital PBXs to newer Internet-based platforms, such as the 3CX phone system.
Discover everything 3CX has to offer in this handy overview.
3CX: an overview
Software-based telephony solutions offer enhanced functionalities and open a variety of additional communication options.
They far outperform their analog or digital counterparts. Meanwhile, older ISDN lines will be phasing out in Belgium and the Netherlands. Obsolete, hardware-based telephone systems, meanwhile, are obsolete and will have little reason to exist as of 2025.
Does your organization still have a traditional PBX phone system? At some point, you'll want to be able to quickly switch to an Internet-based phone solution instead. The advanced features of the 3CX phone system make it easy and attractive for both large and small businesses to switch.
Why are so many organizations switching to 3CX? What are the advantages over traditional phone systems and how do you set it up?

What is 3CX?
3CX is a software-based IP phone system that can be deployed both on-premises and in the cloud. Through SIP trunks, voice, video, data and messages can be sent over an Internet connection. It is a VoIP system with open standards. So you have the freedom to make your own choices about everything from numbers to devices to hosting solution.
With more than 250,000 installations, 3CX is fast becoming one of the world's favorite telecom platforms. Scalable, affordable and user-friendly, it covers voice, video, messaging and chat, offering organizations of all sizes a comprehensive, integrated communications solution.
What are the differences between 3CX and traditional PBXs?
On a traditional telephone system, calls are made over standard telephone lines (ISDN lines). The phone system is often a physical box on the wall or in a data center. This hardware requires regular maintenance and expensive software upgrades.
In contrast, software-based IP phone systems, such as 3CX, combine Internet connectivity with various technologies. Voice calls, video, data and messages are transmitted through the cloud rather than through physical analog or digital lines.
An IP PBX has no limits on outside lines, nor on the number of internal phones and devices that can be connected. These offer all the advantages of new technology and far outweigh the capabilities of older telephone systems.
