I provide tech support over the phones for a company. We don't support Windows and usually refer Win calls to the Microsoft tech support line.
Customer: "I have Windows on my system, and there's something wrong with the number you guys gave me. I can't seem to connect to it."
Tech Support: "What number did they give you?"
Customer: My computer says there's no answer."
Tech Support: "Your computer?"
Customer: "I am trying to connect using the setup wizard that keeps coming up, but everytime I dial out it tells me there's no answer. There's something wrong with that phone number. Could you give me a new one please?"
Tech Support: "Sir, that number is not a BBS. It's a toll-free voice number. You have to use an actual phone."
Customer: "There's something wrong with that number."
Tech Support: "Try using an actual PHONE. NOT your computer. Then see what you get."
Customer: "All right. I'll give that a try. But I doubt it'll work. Thank you."
