Hi Ed,

I haven't read your draft yet, but I just want to make a short comment on
the definitions that you proposed.
You mention the concepts of HomeZone ID and VisitedZone ID. This implies
already to a certain architecture, namely one where the "home area" and
"visited area" of a User are defined to be identified with the accuracy of
one zone. In my contribution to the Red Bank meeting (APC 1659) I proposed
similar "home area" and "visited area" concepts based on Administrative
Domains, which in my mind makes more sense as the Domains have so far in
H.323 been the entities that are responsible for maintaining any information
of their users.
So I propose that we think about the architecture first before defining
these terms.

 Not a nasty, dirty, wet hole, filled with the ends of

sandy hole with nothing in it to sit down on or to eat:
     it was a hobbit-hole, and that means comfort.

                Dear All,

                I have put together the first proposed draft and outline for
                H.323 Annex-H. You can pick-up a copy in:
                http://people.itu.int/~emartine/temp/

                Editor's Special Note:  The interworking  referred in this
annex is
                the interwork of legacy systems to H.323 systems. Not to be
confused
                with interworking H.323 systems to circuit switched hybrid
systems
                or circuit switched adjuncts. The work proposed therewith,
does not
                impact
                the legacy systems or impose new requirements to the Legacy
systems
                to support H.323 terminals or H.323 systems.

                Need to add more sections to the Annex-H  to comply with TOR
e.g.,
                Interworking:

                Network interworking
                connections between H.323 systems and mobile networks (e.g.,
GSM, ANSI
                41, ...)
                connections between mobile H.323 systems and PSTN or other
networks.

                Terminal interworking
                Use of non-H.323 mobile terminals (e.g., GSM handset, H.324
terminal,
                H.320 terminal, etc.) to communicate with H.323 systems.

                Tandeming minimisation
                Non-transcoding of media streams

                Also, it would be nice if we can add to the
                the defiention section:

                Home Location Funtion (HFL)
                Vistor Location Funtion (VFL)
                Authentication user Funtion (AuF)
                HomeZone ID (HZid)
                VisitedZone ID (VZid)
