Haha... I don't know about making them sound Southern, but I do remember reading an article about this stuff - training Indians to make them sound more American, having their screen pop up with the caller's weather info, sports info and stuff like that to make it seem like they're more tuned in to what the customers are experiencing in daily life. Still, it's pretty obvious when you call a center and they're based in India -- besides the obvious accent differences, the call quality is many times shitty, there's like a 1/2 second or so of lag time between you and the agent and all that crap.
