ART sipcore siprec errata The SIP-based Media Recording (SIPREC) protocol is defined by both "Session Initiation Protocol (SIP) Recording Metadata" (RFC 7865) and "Session Recording Protocol" (RFC 7866). Unfortunately, both RFCs contradict each other regarding how recording metadata is to be labeled. In addition, neither RFC registered the new media type. This document updates RFC 7866 to align with RFC 7865 when labeling recording metadata and also registers the media type.
Introduction The SIP-based Media Recording (SIPREC) protocol is defined by and . The former specifies the use of "application/rs-metadata+xml" when identifying metadata content, whereas the latter uses "application/rs-metadata". Since defines SIPREC metadata, it was identified as normative, and was created against to report the issue. This document resolves the erratum. In addition, neither document registered the media type with IANA; this document rectifies this gap.
Updates to RFC 7866 Each instance of the following in :
application/rs-metadata
Is replaced with:
application/rs-metadata+xml
Security Considerations The updates specified in this memo clarify inconsistencies in published documents with regard to identifying recording metadata. They do not introduce new security considerations beyond those listed in .
IANA Considerations
