Ask for "Sales" to make more.
Lori Richardson shares a great tip for reaching a decision maker in a large organization:
… and one of the best strategies I've used is to call in and ask for SALES - you will get someone on the other end of the phone who understands what you are going through - unless they are an admin person, they make calls like you do as well. Determine if you are in the right sales area. Ask them if they have a moment, and then ask about their boss, or boss's boss. Get enough information to make a direct call or email - then fire it off. You'll be surprised at the reply rate when you know a little something about your target or about their organization. Don't forget to send a hand-written thank you note to the person in sales who gave you the inside scoop if you end up with an appointment or had a vaulable conversation - because that will motivate your original contact. It's about goodwill, and what goes around does come around.
