> 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

> 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

> D,
> modified or extended Q.931 for Interface C, and modified or extended H.225

> Please try and get all attendee requests in by Monday the 19th at 12:00
