Abstract: A digital voice processing system wherein voice processing functions are run in software. This application of software allows a modular structure because the application software resides in boards that are coupled to a host computer. With this structure, the software can be updated as required and the capacity of the system can be readily expanded to meet increased needs.

Abstract: A system for storing and forwarding voice signals. The system provides for central, digital storage of voice signals for later access by addressee system users. When addresses access a previously stored voice signal they have the capability to incrementally construct a reply by "toggeling" between a playback state, to listen to the previously stored signal and a record state to record at least a partial response. In another embodiment originators of voice signals have the capability to edit signals after storage.

Abstract: A method and apparatus for storing and forwarding voice signals wherein a user has increased control and flexibility in distributing voice signals. In one embodiment the originator of a stored voice signal may restrict an addressee's ability to forward a message to other users. In another, the originator may limit the addressee's ability to use the voice store and forward system until such time as the addressee responds to a stored voice signal.

Abstract: The network is particularly useful in office communications. The network includes a plurality of transceiver units, each of which can be used as a telephone, or as a dictation terminal, or optionally as an automatic telephone answering machine. The network includes a personal computer for performing various communications and communication control functions. A private branch telephone exchange ("PBX") can be included. Preferably, each transceiver unit includes a visual display for displaying messages. Messages can be sent from the computer to the transceiver units, or from one transceiver unit to another. The messages can be pre-set standard messages, or messages created uniquely. A telephone or PBX operator may send messages through the network reporting missed telephone calls, thus avoiding the need for written notes or other memoranda. The personal computer is used to send, forward, store and log messages. It can do telephone call accounting.

The network includes a personal computer for performing various communications and communication control functions. Preferably, each transceiver unit includes a visual display for displaying messages. The computer stores and retrieves information regarding appointments that the users of the network may have. Daily, weekly and monthly appointment calendars are provided for every user of the network. The user is given a reminder message through the network at a predetermined time prior to the appointment. Appointment schedules for current, prior and future time periods can be viewed.

Abstract: A programmable telephone/dictation terminal that can be disposed in any one of several different modes of operation including, but not limited to, dictating information onto a recorder, communicating over a telephone network, recording incoming messages received via a telephone line, preventing a telephone dial out operation and communicating "text" messages with a supervisory console. The terminal is provided with several programmable keys each being assignable by the terminal user with a particular function such that, upon the simple operation of that key, the assigned function is carried out. The user may change the function to which a particular programmed key is assigned, as desired.
