3CX Phone System

TLDR: 3CX Phone System is a software-based phone system that allows you to make calls using the internet instead of traditional phone lines.

The 3CX Phone System is a phone system developed by a company called 3CX. It's not like a regular phone system that uses traditional phone lines. Instead, it uses the internet to make calls. This is called Voice over Internet Protocol (VoIP). With the 3CX Phone System, you can make calls using your computer, smartphone, or even a special phone that is designed to work with VoIP.

The 3CX Phone System is based on a standard called SIP (Session Initiation Protocol), which is used to set up and manage phone calls over the internet. It allows you to make calls using the public switched telephone network (PSTN) or through VoIP services. You can use the 3CX Phone System on your own premises, in the cloud, or through a cloud service provided by 3CX.

One of the great things about the 3CX Phone System is that it works on different operating systems like Windows, Linux, and even Raspberry Pi. It supports both softphones (software-based phones) and hardphones (physical phones) that are compatible with SIP. You can also use it for faxing, voice and web meetings, and even connect it to traditional phone lines.

The 3CX Phone System was first released in 2006 as a free product and was intended for use in a Microsoft Windows environment. It gained popularity for its easy configuration, management, and compatibility with different hardware. Over the years, new features have been added, such as video conferencing, presence, chat, voicemail, and integrations with platforms like Microsoft Teams, Live Chat, SMS, and Facebook.

In recent years, there have been some security concerns with the 3CX Phone System. In 2023, hackers took over the desktop client of the system and spread malware through a supply chain attack. The company has acknowledged this incident and cybersecurity technology companies have also written about it.

Overall, the 3CX Phone System is a flexible and feature-rich phone system that allows you to make calls using the internet. It offers a range of communication options and can be used on different devices and operating systems.
