  • Patent number: 5664008
    Abstract: A telephone adjunct interface for use with a network-based voice and/or data message storage and delivery service detects and alerts the subscriber to the existence of waiting messages. The interface device utilizes a combination of AC ring detection and outcall polling of the network to determine whether a visual and/or audible notification should be provided to the subscriber. That is, if the subscriber phone is not answered after a selected number of rings, the interface polls the network after a suitable delay to determine if any messages were left. If the subscriber line is busy or on call-forward while a calling party is seeking to leave a message, the network service platform stores the message and waits a selected interval before seeking to alert the subscriber. Advantageously, the device is configured as a small, portable and inexpensive consumer premise unit which connects easily to all standard analog telephone systems that use modular connectors.

  • Patent number: 5625683
    Abstract: A time-to-call and corresponding telephone number are stored in a memory (207) of a radiotelephone (100). The radiotelephone reminds a user that it is time to place a call by emitting a noise through a speaker (105) when a time-of-the-day is equal to or later than the time-to-call. The radiotelephone determines if the radiotelephone is powered on before displaying the telephone number on a display (111). Upon viewing the displayed telephone number, the user can cancel the call or confirm placement of the call to the telephone number by pressing a key (109) or key combination. If confirmed, the radiotelephone automatically dials the telephone number. When a time duration passes before the radiotelephone is powered on, the call is terminated, or the call is canceled, the user has the option to delete the telephone number and corresponding time-to-call from the memory, or change the time-to-call.
