Abstract

PURPOSE:To improve the service for call-back transfer, by transmitting a transfer completion reporting tone to the subscriber telephone set of the transfer request source in the system where a call is transferred by on-hook of this subscriber telephone set. CONSTITUTION:In case of call-back transfer for the incoming call from a trunk line or the like in an automatic exchange, when the trunk line or the like is connected to another extension telephone set by on-hook of an extension telephone set A, the transfer completion reporting tone is transmitted to the extension telephone set A under the control of a central processor CC by closing of a cutoff contact CO due to a network driving device SC, and thus, transfer is confirmed.
