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 • Watch this space… 13
