In what way is this FUD? Voice Age do not claim to represent everyone 
with a patent relevant to the codes they have pools for. From experience 
we know more about the handling of the G.729 codec. Voice Age says they 
represent most of the relevant patent holders. They point you to a 
couple of the others, which they don't represent. If you use more than 
the basic features of G.729 you will find lawyers letters arriving about 
patents Voice Age didn't mention.
