Narrative:
The problem arose when ZDC and or air carrier X failed to make a standard restr entering my sector at 16000 ft. The problem was further exaggerated by the inability of the LR25 pilot to speak english in a manner that would have corrected a problem. I had understanding his call sign was abcd instead of cbad. Eventually, the aircraft's other pilot did the talking, just not soon enough to achieve compliance with my control instructions. Suggestions: all air taxies should be required to spell out the call sign in 'field 11' of their flight plan. There are just too many air taxies now to make it possible for controllers to remember them all (the call signs).
