A single button that serves as a BLF and also a auto icm button does not exist in IPO. You can however use the BLF button as a icm button (ring to the ext) if it shows the user is idle. So for Auto ICM on 3.2 and earlier, you can have a emulation "Automatic Intercom" button programmed onto the phone, press this button and then the User's BLF button, but like I said, only if it shows the User is idle.
