Important.Caller.ID.Information
To use Caller ID and Call Waiting, you must be in an area where
those services are available and you must subscribe to those
services through your local phone company.
Where Caller ID is offered, one or more options are generally
available:
caller’s number only
caller’s name only
caller’s name and number
If you subscribe to Call Waiting ID and Caller ID, the system can
show you the incoming caller information, even when you are
already talking on the phone.
