It is possible that you reached a DID trunk into a PBX. In this case, the ringing, busy, and other 'call progress' tones are not supplied by the C.O., but by the destination PBX. If this PBX generates a double-ring tone toward the calling party (possibly when it generates a double-ring toward the called party) then that's what you'll hear. Were you calling a commercial establishment? A college dorm or campus? Some other place where you were dialing directly to an extension of a large private network?
