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) -- Edgar Martinez - Principal Staff Engineer Email mailto:martinze@cig.mot.com FAX 1-847-632-3145 - - Voice 1-847-632-5278 1501 West Shure Drive, Arlington Hgts.
