Customer: "I need help with this dialer. The police have already shown up to my office twice today."

Police? Ok, whatever.
Tech Support: "Ok, let's check out the settings. Do you have anything entered for getting an outside line?"
Customer: "A nine."
Tech Support: "Do you need to dial a 9 for an outside line?"
Customer: "I'm not sure. I think so."
Tech Support: "Could you double check?"
Customer: "Sure. (pause) Nope. Turns out we don't need it."
Tech Support: "Ok. Then remove it. What do you have for the area code?"
Customer: "One and then [area code]."
Tech Support: "Uhm, you don't need the one. Windows 95 automatically adds that."
Customer: "Oh. So you mean..."
Tech Support: "Yes, your computer was dialing 911 and then the phone number."
