On top of performance improvements to the call manager (SIP server) which allows support for 50% more users on the same hardware, 3CX V20 also features Debian 12 as the underlying operating system. Debian 12 will provide the most up to date security patches until 2026.

New Admin Console

A significant feature of V20 is the brand-new management console, the 'Admin Console,' which is integrated into the 3CX web client. Users can seamlessly transition to the Admin Console within the 3CX web client without requiring a separate login or URL. This update streamlines the configuration process significantly.

By consolidating the web client and management console into a single link, we now have a simplified, easy-to-remember FQDN for both users and admins.

For instance:

In V18: https://company.3cx.us/webclient/

In V20: https://company.3cx.us/

With this user-friendly FQDN and the option for users to set their own password or utilize SSO, there is reduced dependence on the welcome email.

Department and Role Framework

A notable feature in V20 is the introduction of "Departments," comparable to Active Directory Organizational Units (OUs). Departments can be customized to include their own:

Office hours
Holidays
Time zones
Language
Soon to include: Phonebook, CRM configuration & Blacklist
Administrators, managers, and owners

Departments play a crucial role in the new security framework, offering administrators the ability to define permission settings through the use of departments and roles. For instance, you might establish a "Sales" department with a dedicated administrator responsible for user management and IVRs. By default, trunks are system-wide.

Security roles are allocated according to the groups to which a user is affiliated. Consequently, if a user is part of the default group that encompasses all users and is designated as a group admin, they acquire the authority to manage all users.

Preflight Upgrade Requirements

Check if any of the know limitations apply to you below.

V20 Upgrade Requirements

2 Core, 2 GB All 3CX's hosted by Voxtelesys come standard with a minimum of 2vCore and 4GB's of memory, so no worries here.
Sufficient Disk Space needed. Ensure a minimum of 5 GB of free disk space
The source list must remain unaltered for a successful upgrade; any modifications will result in failure Remove any additional source lists. If you are utilizing Microsoft Azure, verify by checking "cat /etc/apt/sources.list.d/microsoft-prod.list."

Not Implemented Features and Roadmap

In an update 1 or final (TBD)

Extension email must be unique and for now can be left empty. In the next update, leaving the email empty will disable Web Client access.

You do not have to specify an email for each extension. So you can omit the email. This will automatically disable Web Client access (so it's also a security thing) This will be good for hotels, hospitals, schools etc everywhere where only a deskphone is required.

V20 requires at least one user with the “System Owner” role assigned. This user should have a unique email address solely dedicated to their role and not utilized for any other extensions. If no System Owner is assigned, a tooltip message will appear, guiding you to set one.
Import sheet will be expanded with group membership and role. We need some time to do this, it will be update 1 or 2.
Multi Edit - we are aware of this and will address this in V20 but not now.
You will need to make a ring group which will email all participants.
