<P>PROBLEM TO BE SOLVED: To provide a communication device in which a call can be made to an outside line easily whether or not it is connected with an extension exchange. <P>SOLUTION: When a call is made to an outside line, an external number is output as it is if the outside line is set in a setting storage unit 341, but the external number is output while adding an outside line identification number if the extension line is set in the setting storage unit 341. Consequently, when the extension line or the outside line is set previously, the user is not required to add an outside line identification number when dialing whether or not a communication device 100 is connected with an extension exchange. Since the user is not required to understand whether or not a communication device 100 is connected with an extension exchange, a call can be made easily to the outside line, and an undesired number can be prevented from being output when a call is made to the outside line. <P>COPYRIGHT: (C)2012,JPO&INPIT |
