Call Authentication
The legacy caller-name lookup system in which the terminating carrier queries a database to find a name associated with the calling number.
In traditional CNAM the calling party does not send a name at all. The terminating carrier performs a dip against a CNAM database keyed on the calling number and displays whatever it finds, limited to 15 characters.
Because CNAM records are loosely governed and the lookup is based purely on the number, a spoofed number produces a convincing but entirely false name on the handset.
CNAM offers no protection against spoofing, which is precisely the gap Rich Call Data and branded calling are designed to close.
Verified display information — business name, logo, and call reason — carried inside a signed PASSporT so it cannot be forged in transit.
Displaying a verified business name, logo, and call reason on the called party's handset instead of a bare phone number.
Presenting a calling number the caller is not authorized to use, in order to disguise the call's true origin or impersonate a trusted party.
