A couple of regular quotes:
Phone rings, and I pick up:
Salesman: "I'm calling to discuss the my email"
Me: "Can't I just reply to the email"
Salesman: "Well, while I've got you on the phone..."
Salesman: "I'm just calling to discuss my email"
Me: "I don't have that in my inbox"
Salesman: "Oh, really? I just clicked send"
Me: "Yeah - email doesn't work quite as fast as your speeddial, I'm afraid"
Salesman: "I just called you about the email I'm going to send to you"
