The IESG has approved the following document: - 'Marking SIP Messages to be Logged' (draft-ietf-insipid-logme-marking-13.txt) as Proposed Standard This document is the product of the INtermediary-safe SIP session ID Working Group. The IESG contact persons are Adam Roach, Alexey Melnikov and Ben Campbell. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-insipid-logme-marking/ Technical Summary This document describes an indicator for the SIP protocol which can be used to mark signaling as being of interest to logging. Such marking will typically be applied as part of network testing controlled by the network operator and not used in normal user agent signaling. However, such marking can be carried end-to-end including the originating and terminating SIP user agents, even if a session originates and terminates in different networks. This document defines a new header field parameter "logme" for the "Session-ID" header field. Implementations of this document MUST implement session identity specified in [RFC7989]. Working Group Summary The work on the document took a relatively long time in the WG. The reason was not so much related to controversies, or different opinions, but more related to the cycles the authors, contributors and reviewers were able to put on the work. There is a consensus in the INSIPID WG to publish the document as an RFC and it has received sufficient review to ensure document quality and technical accuracy. Document Quality A number of vendors have indicated that they have implemented, or intend to implement, the document. Individuals representing the implementers were also involved in the work on the document. The document is also referenced by 3GPP, and support is required for certain IMS use-cases and functions.
