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
  <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 mailing lists by 2014-07-04. Exceptionally, comments may be
sent to instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.


   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.
