Anyone know why series E phones would have different soft keys on a 2400 ImX? This system was upgraded from an ICS and has different 16ELC(x) cards. I haven't checked all lens on the different cards to see if all the phones on those cards have the same soft keys, but I know that the ones with different soft keys are on different cards. I did check the soft key programming and I know that all phones are using the default pattern. Any help appreciated.
