[VoiceOps] ATAs with CAT-iq and HD codec support

[Frank Bulk]

I've been given the impression by some folks that most analog phones don't
do much better than 4 kHz.  I wish there was more solid data out there.

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.
