Hi,
yes, this is possible with ISDN Q.931 and R2, where the called (access number) is transmitted to the CMS.
As you may see in the Q.931 (ISDN) specifications, the originating switch sends the called party number (which number is called) along with the calling party number. This is useful for the receiving switch, as it may serve multiple phone numbers.
