Users running Debian Buster will not see the OS or V18 update in the management console.

If the update is not shown you can check the Debian version with the following SSH command “ sudo lsb_release -a ”. Just sit back and our admins will ensure your 3CX system is updated to v18. If your 3CX instance is Hosted by 3CX, you don’t need to do anything. Contact your 3CX Partner or our 3CX Customer Service Team for further information. If your perpetual license is still within the grace period, you can renew your maintenance. Note: License Refresh only works on version v1 6 or higher. You can see the maintenance expiry date in the management console of your PBX under “ Settings ” > “ License ” or in your customer portal account. Annual license keys are always covered by maintenance but will lose functionality upon expiry. The Upgrade requires valid maintenance on your perpetual license keys. V18 has many advantages over older versions including new features such as Teams integration, new Web Client, and Windows desktop App, as well as many security improvements over older versions.

Check your license, and if you are running on Linux, an OS upgrade to Debian 10 will apply while upgrading to V18. This is a quick cookbook on how to upgrade your 3CX v16 to v18. Self-managed (Private cloud - On-premise).
