Abstract
Two telephone numbers, one for an outside call and one for an extension call, are registered for each of a plurality of one-touch buttons through a procedure the same as that used in placing a call conventionally and without providing new buttons. When an input designating an outside call is made before pressing a one-touch button, the party corresponding to the outside telephone number is called. When an input designating an outside call is not made before pressing a one-touch button, an extension telephone corresponding to the extension call telephone number is called. Since the same one-touch call designating button can thus be used for both an extension call and an outside call, many telephone numbers can be registered with a small number of buttons.
