* Helps you identify who's calling before you answer the phone by displaying the phone number of the telephone from which the call is made.
- Works automatically once the service is installed and activated, but requires an instrument with a display which is capable of displaying incoming calls. You can purchase either an attachment to your current phone or buy a phone with a built in display screen.
- Initially, Caller ID will give you numbers from within your local calling area if you and the person calling you are in specially equipped areas. For other numbers, the display screen will show an out of area message.
- If you want to block your number when you call someone else who might have Caller ID, press "*67" (rotary 1167) immediately prior to placing the call. YOU DON'T NEED TO ORDER PER CALL BLOCKING. It is automatically available to you. There is no charge for this service.
