Its not about the bandwidth. Its about the quality of the voice in
occasionally lossy networks landline or mobile.
Also critically, it's about the latency introduced by the coder/
decoder and by any buffering necessary to account for variable latency
in the network.
Streaming MP3 might sound really good, but it does so at the expense
of lots of buffering that compensates for the variable latency of the
network and associated TCP transport. Trying to use it for a phone
call would not work so well, unless you're used to making phone calls
to someplace well outside lunar orbit.
