Yes, that would work, but then I'd still have to remember who's number is who's. Plus for three locations and five lines, that gets to be a lot of CID boxes. The point I was trying to make was that people in this day and age just expect you to know who's calling. I wish they made a multi line CID box. That would be useful. Where I have partner display phones, I'm set, but again, I don't remember everyone's number and cell phones usually show up as "Cell Phone NH" and the number. Some will show up as the town the exchange is in, but that's rare. I just wish people had the telephone etiquette of the time before cell phones. Goes back to my original point that people think I'm weird because I have to ask who's calling, as if I'm supposed to automatically know. Some of my friends I can distinguish their voice, but some are so similar that it throws me for a loop. Sometimes I just go along with the conversation till I figure it out.
