When you changed from 1FBs to PRI, you gave up the former square key system feature. You are going in the wrong direction if you think another system will restore that to you. As I stated, you cannot have direct line appearances on your phones unless you assign all 23 digital voice channels as direct appearing lines and fill up of your flex buttons. If you have a fractional with perhaps 8 channels or so, you could try it but that is not a recommended method.
