[VoiceOps] Call Quality

[Carlos Alvarez]

Well, no call is purely digital, the endpoints are still analog, as is the
meatbag behind the handset.  I can't imagine any way you can create echo in
the digital portions.  But a mismatch in impedance on an ATA or similar
device would be a common old problem I've faced.
