The caller information is read out if there is information that matches the corresponding caller phone number by using the phone number of the previously stored phone book as a key, and provided as caller information. To provide.

After confirming the caller information, a call is made with the other party through a handset or a connected headset (S606 and S608).

If it is not the normal phone mode in step S600 it is determined whether the mobile phone reception mode (S602).

In the case of the cellular phone reception mode, when the cellular phone is received while the cellular phone is connected, the telephone received by the cellular phone is connected to the phone 200 (S610). Depending on the handset or headset connection state, the user can make a call using the handset or the headset (S612, S614). In addition, the phone call status display unit is turned on (S616).

If it is not the cellular phone reception mode in step S602 to determine the ARS mode to operate the ARS mode (S618).

When the ARS mode is operated, the pre-stored ARS message is transmitted to the counterpart phone through the public communication network (S620).

After completion of the ARS, it is determined whether the missed mode is set (S622). In the absent mode, a short message (SMS) inputted with the received number after the end of the ARS message is transmitted to the absentee (S624).

If the missed mode is not set in step S622, the call is automatically disconnected after the end of the ARS message (S626).

Preferred embodiments of the present invention described above are disclosed for purposes of illustration, and those skilled in the art will be able to make various modifications, changes and additions within the spirit and scope of the present invention.
