wideband codecs carry music a lot better. the can have considerably more dynamic range than you can expect from an 8 bit pcm mulaw encoding (about 45bB). that helps a lot in the speaker phone situation. if you have the opportunity to compare pstn and mp3 recordings of the same meeting like I do on occasion the difference is considerable. > Cheers, > -- jra
