I am newly trying to program a legacy toshiba dk424 (dksub424a and dksue424a) that I don't have much info on. I have the basic manual, which tells me how to change display names, etc. and I've got most of that down. I want to set up a dial by name directory, which isn't covered in the manual. Also, is there any software options for administering this phone system? Any help is appreciated. I know this post is a bit general, but it's my first one, so bear with me.
