Abstract:
PROBLEM TO BE SOLVED: To provide a telephone control device capable of implementing a function for dealing with multiple calls without requiring a high-capacity memory and without complicating state transition of the telephone control device.SOLUTION: A telephone control device dealing with only one call comprises call management number conversion means and further, call management number conversion start/stop means is provided for monitoring a call control command and starting or stopping the call management number conversion means in a case where a predetermined call control command is detected. In a case where a call control command relating to a hold request or a hold permission is detected, the call management number conversion means is started and in a case where a call control command relating to a call disconnection request, a hold cancellation permission, a transfer permission or a call disconnection is detected, the call management number conversion means is stopped.
