In plain words
A cloned voice on a call or a faked video message can be used to ask for a payment or to damage a reputation.
Why it matters to a firm
A voice that sounds like a partner is not proof of who is calling. A payment rule that needs a second person and a known phone number defeats most of these attempts.
How anyone can check it
Agree a call-back rule for any payment request, and use a number you already have, never one given in the message.
