From what I can gather (my boss couldn't tell me) it is a Nortel model 61C PBX. What I am to be responsible for is creating screen "pop ups" that either bring up data from the database on a current customer, or a blank form (with the phone number and caller id coming from the phone system in a text format for us to deciede upon) to add a new customer. Either way, I will need to (I think) create a stored proceedure (or something like it) to do a quick search of the database and send that information to a specific workstation. What I was looking for was information on the way that system interfaces with SQL 2000, either an online reference or a text book. We are not yet close to implementing the system and I want to get more familiar with it. I hope this helps more, any information would be wonderful.
