I dont think APS implementation(G729) is so hard as you think. APS already
has G729 codec support that is if i use APS i must get the implementation of
g729 innerly . i just have to change the procedure to use g729 codec....like
some parameter and encoding decoding technique. ...
APS use 24byte data ...thats a point also...
