G.729 exploits attributes of the human speech to do compression while minimizing the loss of quality. These attributes are not found in music and the resulting compression has poorer quality. Bottom line is that G.729 is designed to compress human voice, not music nor tones. If you used a book-on-tape wav file as your music-on-hold, it would sound great. :) _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/
