Narrative:
ATC vectors kept us high (4;200 MSL) until approximately 7 miles from the runway. We were cleared to 2;000 MSL; and then cleared for a visual approach. Upon descent from 2;000 MSL; ATC advised that he had a low altitude alert. We climbed slightly and continued the approach. Upon turning final at about a two mile final; we were on the visual glide path as shown by the p-vasis. No egpws alerts were encountered; terrain was not a factor. In our opinion; we were intercepting a normal descent profile for landing after having been kept high until very close to the runway.
