The IESG has approved the following document: - 'Session Initiation Protocol (SIP) Recording Call Flows' (draft-ietf-siprec-callflows-08.txt) as Informational RFC This document is the product of the SIP Recording Working Group. The IESG contact persons are Alexey Melnikov, Ben Campbell and Alissa Cooper. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-siprec-callflows/ Technical Summary: This document lists call flows with metadata snapshots sent from a Session Recording Client(SRC) to a Session Recording Server(SRS). Working Group Summary: This document has had a relatively long gestation period in the working group, this is because feedback from real implementations was thought important and also it could not be completed before the SIPREC metadata specification (RFC 7865) was published Document Quality: There are multiple interoperable implementations of the protocol and metadata shown in this draft. Notably, the National Emergency Number Association (NENA) has included the protocol, with the metadata described in this document in itâ??s Next Generation 9-1-1 standard, and has held an interoperability event where multiple implementations were tested. A number of recording vendors provided a detailed review and comments on this draft. Personnel: Andrew Hutton is the Document Shepherd. Alissa Cooper is the Responsible Area Director.
