3CX Linux PBX – Same great features & functionality

The Linux edition of 3CX has achieved feature parity with the award-winning Windows solution while at the same time making the phone system more cloud-friendly.

There are now three different options for deploying your 3CX communications software: Windows, Linux and Cloud – the choice is entirely yours! So if you’re looking to replace your Asterisk®* phone system, or are just looking for an alternative to open source, then 3CX is the solution for you!

Your Linux Cloud PBX

With the Linux version of the PBX, 3CX can be easily hosted in the cloud. Host 3CX on most Linux VPS instances (running OpenStack) and other leading hosting providers such as Amazon Lightsail, Microsoft Azure, OVH and Amazon AWS for a low monthly cost, or free with Google Cloud. The possibilities are endless!

Install 3CX on Linux from ISO

The 3CX Linux ISO

If you are not familiar with Linux or Debian, then you can choose to install from ISO. In this case, 3CX will install Debian 9 Stretch for you with the correct options and subsequently install 3CX as well. Unlike Asterisk® phone systems, 3CX will do all the configuration for you and not compromise on security either.

Open-platform for Ultimate Flexibility

Completely customizable, you deploy 3CX where you want, how you want. There’s no need for pricey appliances and with the ability to use your choice of IP phones, SIP trunks and integrations, 3CX makes for a low-cost, hassle-free solution.
