Thanks for the response!

Ok, it's incredibly obvious that I don't know enough about phone systems to just make this happen.

So I went to the server room and sure enough there are two RS232 ports on the bottom of our bottom cabinet. I connected the serial cable that we usually use to connect to the VM system (VMAdmin) to the cabinet and moved it to a different COM port, but I don't know how I would program the phone system to deliver the data. I figured out that I can "connect" using 2400 Baud via hyperterminal to show that it is connected(it actually autodiscovered) but I don't know how to actually communicate.

How do I go about configuring the phone system do output this data?
