With reference to the minutes detailed in APC 1748: In view of the contributions on extensibility (APC -1683A, TD43, APC-1694, and APC-1737) put forward at the Red Bank meeting, we intend to continue the dialogue with Nortel with the aim of extending their contribution APC-1656 to include a more generic long term solution (as detailed in TD-43). We believe that APC -1656 is a good starting point, but needs further work to include extensibility concepts, from APC-1683A, before 'determination' of H.225 version 4. It is our understanding that the dialogue is an ongoing process, and this should be reflected in the meeting minutes. Morgan Potter.
