Thank you for reaching out!
For legacy versions of RutOS, Events Reporting can be found by navigating to Status → Events Log and selecting the Events Reporting tab.
Then select the Event type, upon which SMS or email will be sent, Event subtype, Action, and press Add. Then specify the phone number. If emails will be used, then the senders' email will need to be configured as well as the receiver's email address.
We also always encourage to use of the latest firmware version for security patches and new features. Firmware downloads for the RUT240 can be found here.
