3. SHAKEN
SHAKEN verifies that the entity originating a call is entitled to use the phone number displayed – nothing more!
SHAKEN builds on the information the originating carrier has about the calling party.
The originating service provider can only attest to “what it knows”.

13. Summary Focus is different, but complementary:
Know Your Customer: focused on the intent of the call
SHAKEN: focused on verifying the source of the call
The “Know Your Customer” initiative should remain distinct from SHAKEN.
Trying to merge the two could compromise both.
Coordination between the two initiatives would be valuable:
Ensure necessary functionality is supported
Understand limitations
Coordinated messaging
