    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.},
