When I need to busy out a port, I just dial out to the port's own
number, at least in my area, this will busy the line (since the line
is off hook, and the number being dialed will always be busy.  I'm not
sure how your hunt works, but here, only the original number will
forward into the group, so if you call a number in the middle of the
group, it is not forwarded.  I guess this couldn't be used on the main
number, as you'd get forwarded to your next port.
