| RFC 9806 | Correct SIPREC Metadata Media Type | June 2025 |
| Mongrain | Standards Track | [Page] |
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.¶

The SIP-based Media Recording (SIPREC) protocol is defined by [RFC7865] and [RFC7866]. The former specifies the use of "application/rs-metadata+xml" when identifying metadata content, whereas the latter uses "application/rs-metadata". Since [RFC7865] defines SIPREC metadata, it was identified as normative, and [Err7987] was created against [RFC7866] to report the issue. This document resolves the erratum.¶
In addition, neither document registered the media type with IANA; this document rectifies this gap.¶
Each instance of the following in [RFC7866]:¶
application/rs-metadata¶
Is replaced with:¶
application/rs-metadata+xml¶
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 [RFC7866].¶
[RFC7865] defines a media type for use with specifying recording metadata in XML data. This media type is to be used when specifying recording metadata in SIPREC.¶
