We've just finished an install of Unity. Our field folks have a mailbox on the server, and we set notification to their cell phone via device pager. Works great, but they are all getting a missed call from the 1800 number associated with the system - at 0130 in the morning. Not all users are getting the calls at the same time.
I ran the Port Usage analyzer, and there are zero dial outs during that period. Setting the enabled hours has eliminated the calls, but I still don't know what caused the calls in the first place. Is there any kind of "new day" event that I might have missed that's perhaps flushing these calls back to the cell phones? Any other ideas would be great.
