I could have done that indeed but I usually get handed off to LFOB approach right after leaving LFOE airspace so there is no point for me to contact Paris ACCs. Beauvais (LFOB) controllers are working along with Paris center controllers in order to keep us clear of conflicts.
Descending to 2500 straightaway is easier for me and for the ATC as they always ask VFR inbounds to remain outside the Class A. Not to mention than Paris airspace is an absolute nightmare for VFRs (very complex airspace with a lot of frequencies)...
Here is a simplified chart of Paris Airspace, the two TMA I need to avoid are 4A and 5A.
Here are the frequencies of this airspace.
