Cougar try reading the AIP instead of just arguing what you want.
Jeppesen ATC, AU-719, 6.5 says;
"Before descending from controlled into Class G airspace and before separation with any aircraft operating near the base of controlled airspace can be compromised, the PIC of an IFR flight must report position, level, intentions & estimate for next position/destination to the ATS unit providing services in class G airspace."
Therefore, one basically has to make a position report at some point in CTA with a statement of intention.
