Dear Brian, I am documenting a piece on the "minimal interoperability" issue, which I will forward to you next week. (if there is interest I can post it to the list)
The basic idea is that while the motivation for H.GCP was gateway decomposition, the actual standard deals with composing rather than decomposing.
Thus I propose to introduce some terms, such as "composite gateway", while adhering to H.323 current definitions, and work on the call setup procedures, closely following the actual H.323 text. This will lead to the resolution of transfering call signalling between the MGC and the MG in the various compositions. One thought that crossed my mind was to explicitly deal with all the gateway categories that H.323 defines ( H.310 (H.320 on B-ISDN), H.320 (ISDN), H.321 (ATM), H.322 (GQOS-LAN), H.324 (GSTN), H.324M (Mobile), and V.70 (DSVD)).
We may also need to modify H.323v3, at least to some extent, in order to better cover gateway sub-components.
A sample of the text is attached (Word 97)
