I spent 6.5 years in a call center for a smallish (really only covering a single state) dial-up internet service. Everything you say is true. Though I'd add the caveat that while I am more comfortable talking to strangers after that experience (I was, and still am, a shy introvert), I now loathe speaking on the phone, even to friends/family, where before, I had no problem talking on the phone for hours. I now try to use email/text messages as much as possible.
