The audio quality should be identical. The reference code that is 
available from the ITU is the basis for every G.729 implementation I 
have seen. The Intel IPP enhanced version someone made available 
recently is still based on the ITU code. The licenced version from 
Digium is too. If one version sounds worse than another the implementor 
must have done something wrong. The core G.729 code should always sound 
the same.
