I am getting reports from people in our offices that all of a sudden their phone goes blank which in turn causes the PC connected to the phone to loose connectivity. Here is what they have told me they do. They connect the PC directly in to the wall jack that the phone was connected to and the PC connects. They then take another phone and connect it to the jack in question and that phone works. They then take the phone in question and connect it to another jack and it works again. So they that the original phone and reconnect it to the original jack in it still will not work. I checked the interface for errors and there are none. Now I am being told it is happening and another location. I cannot confirm what they are telling me but I don't think they are misleading me...but this makes no sense to me. Has anyone seen or heard of anything like this?
