I noticed that some numbers are displayed as "1234" or just "1" or sometimes more than 16 numbers on the call blocker when I receive a call. Is this format legal?
No, not on the public network. According to BellCore Publication TR-NWT-000031M, Issue 4, December 1992, it states as a Requirement that: All calling line Directory Number (DN) shall be transmitted in Calling Number Delivery (CND) to the Customer Premises Equipment (telephones) in a 10 digit format. As of late, this network protocol is being completely ignored by internet spoofing of a number. Since the internet is not policed by the FCC, this leaves spoofing open to whoever wishes to employ those spoofing services. However, the Digitone Call Blocker adheres to these requirements and compels the calling number received to fit within these 1992 guidelines or be blocked.
