Abstract An automatic dialling method of the digital telephone double audio aims at emitting the number information exsisted in the control circuit to give the signal to the mobile telephone earpiece by control circuit through the function key control in order to let it transmit double audio signal to outside. The fixed telephone receiver receives the signal and converts the signal into a electrical signal to be emitted to the fixed telephone exchanger which issues the dial order to dial the telephone wishing to call. With the above method the passive receiving of the mobile telephone calling changed into a active calling to outside of the fixed telephone and in the above operation there is no rediation since the radio frequency part of the mobile telephone does not work.
