Getting the ati-d to work is you first need. Changing the ports to vm will cause the system to send a digit to the port rather than dial tone so when you go off hook you should hear a dtmf tone("1" I think). you should be able to dial 9 and get a line. You might try to change them back to ist to make sure you ati-d s (I am assuming that you have two of them for your four ports) are working. When you are calling them are they hooked up to the Debut? TRy unhook them if they are. To test the debut try hooking it up to a co line and call in to make sure its not the problem.

Turning on VVM is what makes it serial integration. It can work with just vm turned on the ports.

Keylink would realy help with you programming and I bet someone would be willing to send it to you.
