I believe that you can also turn on "DSS Alert" which is a single "beep" notification whenever a call hits a DSS key. I believe that is a system-wide parameter, so if you turn it on for one phone you turn it on for all of them. I don't think you can do it on a phone by phone basis like you used to be able to do in the olden days.
