Is it possible?

should be doable.

For the ICR you want to block all calls without CLID on do this:
Line group:0
Incoming Number: the DDI you want to block non-CLID calls on e.g 4161231234
Incoming CLID:? or ! (? means number not available. ! means CLID is withheld) You'll have to test with both depending on what your provider is sending you. I suspect that ! is the one you want
Destination: create a unique shortcode e.g. *6001 / Barred, insert this shortcode in this field. An alternative would be to send the call to an AA (with no actions) or VM Module (message, followed with a disconnect) that tells the caller that calls are not accepted at this number when CLID is blocked or withheld. If you want to do this the destination is AA:NoCLID, or VM:NoCLID, assuming that NoCLID is the name you gave the AA or the VM Module.

Test it from a phone you can block CLID on.

If it works, only calls to 4161231234, which are withholding CLID should be blocked. The ICR can be copied (same DDI), the incoming number field = ! blanked out, and calls which do not withhold CLID can be sent to another destination (user/group/AA etc.)

Just leave the target empty, then the caller hears a error message from the provider in stead of a busy tone as if the number does not excists.

Unfortunately later releases of manager do not seem to allow this (I always thought it was a nicer way to achieve this as it did not confirm the eixstance of the number )
