3.92.4. Address Previous topic Parent topic Child topic Next topic

Address specifies what details in the incoming request will be used in the 'Address' field sent to Duo. The contents of the field will show up in the Duo logs. It does not actually have to be an address (which in any case is not usually available until after authentication is complete), and the default of Calling-Station-Id might be a sensible option.
Address %{Calling-Station-Id}
