I think you have to be more specific when you say "bad voice quality". Like what? Worse than a cellphone call? Gaps
of audio missing? Robotic or "cyborg" sound? Static? A background tone or buzzing?
iLBC isn't any worse voice quality than other LBR codecs (GSM-AMR, EVRC, etc). If you want land-line quality and what
you're hearing is cellphone quality, then you're asking too much. Otherwise, suggest to be specific and detailed in
describing your problem.
