The IESG has received a request from the Sip Traversal Required for Applications to Work WG (straw) to consider the following document: - 'A Media-based Traceroute Function for the Session Initiation Protocol (SIP)' <draft-ietf-straw-sip-traceroute-02.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2014-07-04. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract SIP already provides the ability to perform hop-by-hop traceroute for SIP messages using the Max-Forwards header field, in order to determine the reachability path of requests to a target. A mechanism for media-loopback calls has also been defined separately, which enables test calls to be generated which result in media being looped back to the originator. This document describes a means of performing hop-by-hop traceroute-style test calls using the media- loopback mechanism, in order to test the media path when SIP sessions go through media-relaying B2BUAs. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-straw-sip-traceroute/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-straw-sip-traceroute/ballot/ No IPR declarations have been submitted directly on this I-D.
