Abstract

Caller name is authenticated using authentication certificates issued by a registration authority that registers callers who wish to terminate calls to callers subscribed to the registration authority. In one embodiment, the authentication certificates are sent to a called device or a proxy for the called device via a path that is separate from the call setup path. An indication is conveyed to the called party to indicate whether the caller name was successfully authenticated.
