Adding additional AP to 1852i Controller

Having issues adding three additional AP to the 1852i Controller. I have the primary controller setup on 1 of the AP, but when I connect any of the other 3 1852i APs, the controller is not able to detect it. Following the instructions, it says I could just connect the other APs and ensure it is on the same subnet, and they are.

I am able to access the management page of the controller through a web browser.
All the APs are connected to Catalyst 3560-CX - 12 Port.
My Cisco 7925G phone is connected to the wireless from the controller AP and it is making calls.

Not sure if I missed a step in the setup process to ensure any additional APs I connected to this same subnet will be recognized by the controller.

Any ideas on what I could do to get the other APs to be recognized by the controller?
