"... the frequency of voice is not among the most quoted VoIP problems. Those are rather jitter (poor synchronisation of voice packets arriving) and no voice at all or packet loss. Actually almost all PSTNs use the 8kHz frequency that no one has ever complained about before, so necessity for the HD voice quality is somewhat questionable."
