Abstract

PURPOSE:To easily execute a forwardable address setting from a frowardable destination by providing a special number different from the number for forwardable address registration and executing the forwardable address setting. CONSTITUTION:When the subscriber of an extension telephone set A goes out for an extension telephone set B of a forwardable destination and operates a special number different from a normal special number for forwardable address registration provided on the telephone set A with the telephone set B, the fact that it is the forwardable address setting from a transferring destination is decoded by a CPU. Next, when the telephone number of the telephone set B of the transfer destination is dialed with the telephone set B, the CPU judges the extension number of a forwardable address destination, and the forward address setting from the telephone set A to the set B is executed. Consequently, when the forwardable address is requested from the telephone set B to the set A, the forwardable address setting from the forwardable destination is executed easily without forwardable address setting of a receiver with the telephone set A.
