  • Patent number: 6671370
    Abstract: A telephone system includes a plurality of telephone terminals wherein a call that is placed from a calling telephone terminal to a receiving telephone terminal is announced by activating a standard ringing indication at the receiving telephone terminal. A data file is provided having a plurality of different ringing indications therein. These ringing indications include a plurality of sound information that are both different from each other and different from a standard ringing tone, and a plurality of different visual information. When a call is placed from a calling telephone terminal to a receiving telephone terminal, the user at the calling telephone terminal may optionally elect to announce the call at the receiving-telephone-terminal using ringing indication that is selected from the data-file, for example sound information that indicates the identity of the calling-users, and/or visual information that indicates the priority of the call.

  • Patent number: 6633758
    Abstract: Methods and devices for modifying operational modes in a communication device based on application specific parameters. The operational modes of the communication device are modified by adding the application specific parameters of the application to the operational modes of the communication device. Further, commands may be automatically launched after an operational mode change in a communication device. One or more commands to be automatically launched when an operational mode becomes a current operational mode currently used by the communication device are entered into the operational mode of a communication device of a user. Whether the current operational mode has any commands to be automatically launched is determined. The one or more commands are automatically launched if the current operational mode has any commands to be automatically launched.
