name: RCD
full_form: Rich Call Data
context: RCD is described in an IETF draft draft-ietf-stir-passport-rcd-12 [42]. RCD is of two main categories. The first data is a more traditional set of information about a caller associated with "display-name", typically a textual description of the caller in the SIP INVITE. The second category is a set of RCD that is defined as part of the jCard (JSON format for vCard) as specified in RFC 7095 [43]. RCD is inserted in the SIP Identity header token and is digitally signed. If a session is not authenticated and signed then RCD cannot be used. While RCD can be provided by an originating authentication service, an intermediary in the session path could also acquire RCD by querying a third-party service. Such a service effectively acts as a STIR authentication service, generating its own Identity token including RCD, and that token could be attached to a SIP session by either the originating or terminating side.
description: Rich Call Data (RCD) is a set of information about a caller that can be included in the SIP Identity header token, providing more context about the caller. It can include traditional information such as display-name and jCard data.
explanation: The provided context describes RCD as a specific type of data used in telecommunications, particularly in SIP sessions, but it does not fit into any of the predefined categories directly related to network functions, protocols, or services. Therefore, it is classified under Miscellaneous.
