>         As a place to start the discussions, I think we need the following

>         New Protocols:
>         *****************
>         Interface A - Device Control Interface
>
>         New H.246 Annexes:
>         ************************
>         1) H.323 to Voice/Voiceband Terminals = The breakdown of the
> media.
> How DTMF
>         is converted to/from UserInputIndication messages, etc. (There is
> a
> draft of
>         this in the current H.246 Annex B)
>         2) H.323 to SS7 (Similar to Q.699 - a Q.931 to ISUP conversion
> spec)
>         3) H.323 to Q.931 (Similar to the section in Annex A for H.320)
>
>         Interface B, C, D
>         ********************
>         For the Proposed Interfaces B, C, and D. Given that the messages
> passing
>         across these interfaces must reflect all of the content of the
> signaling
>         that the respective signaling functions receive from and send to
> extern
>         entities, aren't these protocols modified or extended ISUP for
> Interface D,
>         modified or extended Q.931 for Interface C, and modified or
> extended
> H.225
>         for Interface B? For C & D, can they be the real protocols if
> carried on a
