An analog handset will pass the analog signal with all of the fidelity of the microphone. The ATA could sample at a HD rate (22kHz ??) and present the additional data to the HD codec. Granted analog phones don't have the best microphone available but it will easily be able to out perform the current 4kHz limitations of the PSTN.
