Have recently installed several new (used) sets to our Norstar and Star Talk Mini system. We have chosen "236" as one of the set DNs, but cannot get that set to open its assigned mailbox which is also "236". I have discovered "Feature985" reports that "236" is something called the "Star Talk intercom number". I suspect that this has something to do with the problem. Can this "Star Talk intercom number" be changed to something else? And, if yes, how do I go about doing so? Any light you can shed on this would be both most helpful and most appreciated!
