Hi Jonathan, Thanks for the quick response. I will read through these drafts and see what I can do with it. The fact that it "remains controversial" sounds like there is not a lot agreement on whether this should be supported by SIP or that the proposed solutions aren't good enough (whether technically or politically). What is the real problem?

Some of the recent drafts on it: http://www.watersprings.org/pub/id/draft-peterson-sipping-retarget-00.txt http://www.watersprings.org/pub/id/draft-jennings-sipping-connected-00.txt There remains strong interest in solving this "connected party problem", however. -Jonathan R.
