Hi everybody - I have a quick question regarding the four soft buttons directly below the LCD display on the Nortel 1230 sets. The first button is labeled "Feat." to access features. The other three buttons, however, are blank. Is it possible to program these buttons with features, or are they unusable in the UCx? I'd like to move a few features already programmed on the main buttons down to these free buttons if possible so I can use the main buttons for BLF's. Thanks for the help!!
