Also, you are apparently saying that Columbia Pike picks up the pay phones in the Pentagon. However, it's interesting to note the "melted cheese" (prefixes which serve the same rate area but, aside from such border situations, different geographic areas). I think I noticed some such "noise" around Broad Street and Vine, on or near the border in Philadelphia between "center city east" and "center city west" groups of prefixes in Phila. zone 1. Back to Va. suburbs in DC area: How close to the boundary between Columbia Pike/Crystal City and Old Town Alexandria is National Airport? (You noted National Airport as having some Old Town Alexandria prefixes among its pay phones.)
