Caller ID issues: an incoming call to my personal or business line often displays only an area code and phone number, but the caller’s identity or business name is not displayed. Why? I pay for the caller ID feature on my business line to display my business name to others on all my outgoing calls, but when I make a call from my business phone to my own personal line, my personal line does not display the name of my own business instead it just displays the area code & phone number of my business line.
