When upgrading to v20, you’ll be taken to Debian 12 in two steps; first to Debian 11, and then to Debian 12 after a restart.  You’ll be on the latest–and greatest operating system available today!


Secure deployment of the new 3CX Windows Softphone via the Microsoft Store

3CX Microsoft store app

This new type of deployment offers tighter security right from the onset– each Windows native app is security checked by Microsoft, which helps avoid any situations like the one earlier in the year.

Deploying via the Windows store also allows updates to occur separately from the main 3CX build for better manageability.



Two Factor Authentication (2FA) provides another layer of credential security for the 3CX client. Single Sign On (SSO) has been enhanced and is now easier to deploy in Microsoft and Google.


One URL for Admin/Web Client & Secure FQDN Everywhere

 With the client and management console merged into one site, 3CX now has one easy-to-remember FQDN for users and admins.


 Before v20: 


 New with v20:


 Users have the ability to set their own password, enable 2FA, or utilize SSO.  This reduces the reliance on the welcome email altogether.
