Is the On-premise Server automatically updated when a new version is available?

Zello Paid support

No, the on-premise server does not automatically update. To receive updates, you must have an update subscription; once subscribed, you’ll receive notifications of new updates–as well as instructions for installing them–via email.  

The initial Zello Work on-premise server licensing fee includes a year of updates and support. After that year, an annual renewal fee is required for technical support and updates.
