Abstract
In a call transfer apparatus wherein a request to transfer a call between first and second communication partners from the second communication partner to a transfer destination is made, a discriminating circuit discriminates whether the transfer destination can respond. A control unit places the first communication partner in a holding state while it is determined whether the transfer destination can respond. If the transfer destination can respond, the call is transferred. If speech communication with the transfer destination is not possible, the control unit releases the holding state of the first communication partner.
