What does this API do ?

The Verified Caller API enables enterprises to send operator-authenticated “business card” information to a customer’s mobile phone when making an outbound call. This business card can include the caller name, call purpose and, depending on implementation, richer media such as a logo, image, or video. The API helps customers recognise legitimate calls before answering, improving trust, reducing call avoidance, and supporting fraud prevention.
