I have a station (8410 phone) that is acting oddly. You cannot call the number, it will give beep sounds when calling into. You can call out with no problems; both to outside numbers and inside 4 digit dial numbers. Seems like the phone is programmed for like a Do Not Disturb situation...but I have tried the #2 to deactivate call forwarding Busy. IS there some other programming option I should be aware of to look at? Send All Calls is not activated either. I also tried moving the station to another port on the Definity system to see if there was a clitch, to no improvement. Can call out on the station, but cannot call into??
