I am having a very wierd issue configuring intercoms on a new installation. We use extensions in the 100 range, so I create an intercom as *100, *101,*101 and so on. I have done this many times before and it works like a charm. The issue that I am having is when I hit *1, I get a secondary dial tone. If I create an intercom that is *200. It works fine. The funny thing is that if I dial *1, then *100 the intercom works fine. I have searched the configuration for a dial peer that might be overlapping but I cannot find one. Thank you for your assistance in this matter.
