<p>The inventive system incorporates one or more exchanges and plural terminals, which may interconnect through the exchanges. A calling terminal signals for 'call-back' after connection with its own exchange has been cut off. The calling user then inputs the called subscriber number, which is stored in a buffer, e.g. in the calling terminal's subscriber identification module apparatus. The calling terminal exchange then sets up the desired connection, which may include wireless paths, reading the required number from buffer storage. The originating user is then called back when the connection has been completed.</p> |
