Hi all,

I regret that I will be unable to attend the Beijing meeting.

Re AVD-2464, (on H.245 OLC Master/Slave conflicts), the proposed material 
appears to be redundant with the existing text in C.4.1.3/H.245 and 
C.5.1.3/H.245.

Perhaps I misunderstand.

If I remember correctly, this issue was discussed in Geneva, and one of the 
reasons given for adding this text was that some implementations do not 
follow the procedures of C.4.1.3 and C.5.1.3 correctly (that is, they don't 
handle Master/Slave OLC conflicts per those clauses, which can break 
interworking).

If that is the main motivation, I suggest that it would be better to point 
out the existing text of C.4.1.3 / C.5.1.3 of H.245 to the implementors so 
they can correct the bug, than to add redundant text, which may make it 
more difficult to read and understand H.245.  This could have the 
unintended effect of making mistakes in understanding H.245 more likely (by 
adding complexity to the document), rather than less.

Best regards to all,

--Dave Lindbergh
