Thanks, Sandras. The G.723.1 patent is on the standard itself. Now nothing i can do except pay fee for it. 
I am testing the ffmpeg.

I really wanna add G.723.1 codec to openh323 and it seems that openh323 does have a skeleton of G.723.1 . it is an empty codec using ITU-T test code.  I tested the ITU-T ANSI C codec, the encoding is poorly slow, decoding has no problem.
