I have a Quadro M32x with 77 extensions and I need to assign a different code for each extension when they want to make a call by dialing (9001 *) as it could do?

I've been trying to setup the Quadro 6L and encountered problems activating the FXO. Could you help me to solve this problem?

How can I activate the FXO on a Quadro 6L?
