Does the InvizBox protect my phone line?
The InvizBox can only protect devices that are connected either via ethernet or WiFi.
If your phone is digital and is connected to the InvizBox via ethernet (such as a VoIP phone), the phone line would be protected by the InvizBox.
If you phone is connected to your modem, phone socket or microfilter, the InvizBox cannot protect your phone line as the phone is not connected to the InvizBox.
