Invalid Caller ID Filtering

The ability to restrict inbound/outbound calls if the CallerID is not formatted in a legally-permissible format. This feature does not confirm sending identity, as that is handled by the STIR/SHAKEN feature. Examples of improperly formatted Caller ID: less than 10-digit Domestic number, Toll Free number, Restricted Area Codes (200, 555, etc), or numbers containing an NXX of 555.
