Update 6 has come out of our test cycles with flying colors and has already been deployed thousands of times. Therefore we are releasing Update 6 as Beta and making it available as the default install option as follows:
- New on-premise Linux installs deployed from our portal will be installed using Update 6
- All StartUP instances will be updated to Update 6
- New Hosted by 3CX Trial and NFR deployments will use Update 6
Existing installations can install Update 6 via the updates page but keep in mind it's still a Beta release.
New on-premise Windows installs will be deployed using Update 5 and cannot be updated to Update 6 yet.
We envisage making Update 6 final early next year. It will then be deployed to 3CX hosted and other installations on demand or automatically based on your setting and preference.
New in Update 6 Beta: DHCP Option 66 support
In Update 6 Alpha we had disabled DHCP 66 somewhat hastily and it is back now in the Beta release. The reason that DHCP 66 had been disabled was to increase security in cloud installations. We do not recommend using DHCP Option 66 in cloud deployments but it's certainly possible to use it on the local LAN providing the network is properly secured.
We are working on a new secure way to deploy phones en masse in the cloud using the SBC and PnP. Meanwhile, you can deploy Supported IP Phones using DHCP Option 66. Check out our DHCP Option 66 guide.
Check out all the new features in more depth on the V18 Update 6 Alpha blog.
How to get V18 Update 6 Beta
- Current V18 Update 5 & Update 6 Alpha users running on Linux can try out Update 6 Beta via Updates in the Management Console.
- StartUP users simply log in to the Web Client. You will see a banner at the top of your screen saying ‘A new update is available. Refresh now?’. Click “Yes”.
