Even a pure VoIP path is no guarantee; many IP phone manufacturers use
such cheap components that their "wideband" audio doesn't sound as good
as other IP phone manufacturers' "narrowband" does.

Analog phones are probably even worse; the manufacturers /know/ that
they're going to be plugged into the narrowband PSTN, so why would they
think to use better components?
