I need some major help with programming aa on this star talk. I have managed to at least get the message to answer when a call come in but I have no idea on how to point it to each ext. There is only 4 people that is on this system. I install key systems every day, but this is a first for me.I am really struggling and need some help. I also can not get some old recording off, but I did set them so they would not answer, I would appreciate any help in setting this thing up. So when someone dials 1 it goes to ext 21 and so on PLEASE HELP
