Research on History of Automated Operator Services (

I am working on a dissertation thesis based on who the founder of automated operator services (AOS) technology was. I'm specifically interested in who developed AOS in customer-premises equipment, such as in hotels or airports.

By trade, I am a freelance reporter. While working on a story about the history of billing and collections, I discovered that there is a great deal of debate as to whom founded AOS, and I've decided to prove in my dissertation who that person is. That's why I'm looking for help.

If anybody remembers what the first companies were to develop AOS in hotels or airports, I'd be very interested in talking to you. You can reach me by phone or email.
