Its only G.722.1 Annex C (the 32k sample/second version) which is 
royalty free, and there seem to be some funky conditions in the 
licencing which may cause licence conflicts with other code. The spec in 
the main body of G.722.1 (the 16k samples/second version) is not royalty 
free, and that is the rather more interesting codec for most people. I 
doubt G.718 or G.719 will be in any way open.

On top of that, the only open source software developer I know to have 
contacted Polycom about a licence for G.722.1C has failed to get any 
response after multiple tries.

Steve
