I tried looking up the current issue I am having myself, on the forums to no avail. Perhaps I did not put in the right search perimeters. The issue I am having is this: I have four Cisco 7960's in my house that all ring when dialing one extension. For example, I call from the living room to my daughters room upstairs, and my wife picks up the phone in our office thinking I am calling her due to all phones ringing at the same time, when in fact I dialed my daughter's extension. How do I remedy this issue to where I dial one extension and have only that phone ring? Thank you in advance.
