Shortcall is most certainly the start of a RAP. Shortcall is not the start on an FDP.

Read the FAR...

FAR 117.21.(c)(3) For short call reserve: For an unaugmented operation, the total number of hours a fightcrew member may spend in a fight duty period and a reserve availability period may not exceed the lesser of the maximum applicable fight duty period in Table B of this part plus 4 hours, or 16 hours, as measured from the beginning of the reserve availability period.
