Just to be sure, let me stress that we are talking about
dialog-transparent proxy stuff all the time, nothing like B2BUAs where a
single dialog would be split into two dialogs for the sake of, say,
media translation. Regular, dialog-transparent proxying is what my
single-dialog approach is dealing with only; nothing more, nothing less.

If that's not an issue, I believe we have a fundamentally different
understanding of what a SIP dialog is.

Could you elaborate on this please? I'm wondering because the number of
media connections should not change no matter how many spirals there
are, no matter whether there is just one or multiple dialogs used to
track the spiraled call flow. It will still be just one end-to-end SIP
connection with a single media connection.
