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.
