IANA Registration for vCard Enumservice
This memo registers the Enumservice "vCard" using the URI schemes "http" and "https". This Enumservice is to be used to refer from an ENUM domain name to a vCard instance describing the user of the respective E.164 number.
Information gathered from those vCards could be used before, during, or after inbound or outbound communication takes place. For example, a callee might be presented with the name and association of the caller before picking up the call. [STANDARDS-TRACK]
