> Dear Brian,

>
> 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.
