Pacific Bell (now at&t) it works that way, go off hook on any line in the hunt group, and dial its own number, it will hunt to the next line in the group.
GTE (now VeriZon), only calls directed to the pilot will hunt. Calls directed to any other line in the group will ring if idle, but NOT hunt if busy.
(I'm in an at&t area, but VeriZon territory starts 30 miles south of us)
Our most popular CLEC does it that way as well, they say it's easier from a programming standpoint.
So clip onto line 1, call it, see if it hunts to line 2. Hang up, take a pair of nested bridge clips and stick them between line 2's bridge clips, to busy it out, and go back to line 1 and call it again. Line 3 rings, lather, rinse, repeat
