System Admin Module

This wiki covers both the free and Pro versions. For a summary of function availability, please see the feature matrix. For individual function use, please see the respective guide below.



What is the System Admin Module used for?

The System Admin Module allows you to make changes to your Network Settings, DNS, Intrusion Detection System, Notification Settings, and Time Zone.  It also allows you to power off or reboot your system, register a license to use Commercial Modules, and see the usage of your hard drives.

How is the System Admin Module related to the other Modules?

The System Admin Module allows you to make changes that are related to the operating system that powers your phone system (CentOS Linux), and is not directly related to any of the other modules. It does provide a secure and very limited service to itself and a few other modules, such as the firewall module, to access operating system level functionality such as network level controls. This limited functionality is very narrow in scope for very specific tasks, and the framework does a GPG verification against a few privileged GPG keys each time prior to allowing these limited scope operations to execute.

How Do I Get to the System Admin Module?

  • On the top menu click Admin

  • In the drop down click System Admin

How Do I Use the System Admin Module?
