Hi, I have a lucent phone. 4 of the buttons on my phone are not programmed. What i want to do is program the 8 lights, on the phone that are left, for 8 extensions. I want it to light up if someone if the extension is busy. I guess my basic question is, A)how can i program these lights to do it B)what doc would this be in on how to do it. C)can i program both lights on 1 button to have seprate functionality. or D) am i just dreaming here?
