Abstract

PURPOSE:To attain transfer by storing identification information of all extension subscribers belonging to a transfer group so as to allow an extension subscriber desiring the transfer to eliminate the need for dialing a telephone number of an extension subscriber being a transfer destination. CONSTITUTION:When an extension subscriber B desires the transfer to a subscriber X belonging to the same transfer group G1 while the subscriber B talkes to an extension subscriber A, the subscriber B informs orally the transfer to the subscriber X. When the subscriber X calls depending thereupon, a central controller CC sets a channel p2 to a network NW and returns a dial tone DT to the transfer destination subscriber X. When the subscriber X listening to the DT dials a predetermined specific number, the central controller CC analyzes the number dialed by the subscriber X, and when it is decided as the specific number for transfer reception, a subscriber data area SD(X) is referenced, the controller CC extracts position information of a transfer area SG(G1) and connects the subscribers A and X.
