Abstract
An on-demand caller ID service is disclosed. A customer dials an access code to retrieve calls made to his telephone number. An automated voicemail response system would repeat the telephone numbers and/or names associated with those telephone numbers that called over a predetermined time period, such as the last 24 hours. The customer is billed a per usage charge for each time he accesses the service. The customer may also subscribe to the service. Customers that are not subscribers of caller ID may utilize this service if they are seeking to track down an incoming call that may have been missed during the day. Also, customers who are away from their telephone line may remotely check who has called them by accessing the service.
