even if you have it set to automatically grab a line it will always go from the bottom up (3,2,1). nec's are like that.

in program 4-23 for the port(s) you want to automatically grab a line put a 9 in there. then transfer to write.

note this! if you do this, AND if you need to do intercom calls, you'll have to put an intercom button on the phones! because after you do this if you press the intercom button it will grab an outside line instead of giving you an intercom tone.
