Amen!  A voice of reason. "Let's use a really, REALLY low-quality
codec to save bandwidth and then make it so the tech support calls
from the US go to places where the agents don't really speak English.
That way it will be both hard to hear and difficult to understand.
That'll save BOATLOADS of money!" Uh yeah. First off, Americans can
barely speak English. Secondly, if you make it difficult for people to
hear and/or understand each other then all that money you're saving
with smaller bandwidth will go to things like higher telecom costs
(longer phone calls) and higher payroll costs to cover the additional
personnel needed by these call centers.

As usual, thank you Steve for an enlightened viewpoint that makes
others think about the big picture.
