I was looking at H.245v7, and we have added a field called g729Extensions to the g729 audio capability. In the g729Extensions field there are boolean flags for G.729 annexes A, B, C, D, E, F, G, and H.

There is a paragraph saying:

g729Extensions: indicates capability of additional optional modes of G.729. This codepoint shall not be used to indicate g729AnnexA, g729wAnnexB and g729AnnexAwAnnexB, for which g729AnnexA, g729AnnexB and g729AnnexAwAnnexB shall be used.

So my question is: when are the Annex A and Annex B flag used in g729Extensions?

Thanks.
