Abstract: Transmission-record information is created based on information that has been transmitted to a user communication device in response to a first user call for utilizing an information provision service. The transmission-record information is then transmitted to an operator terminal device that responds to the first user call or a second user call different from the first user call. The second user call is another call from a user who has transmitted the first user call by the user communication device.

Abstract: A caller number received from an exchange machine by a telephone coordination server (CTI server) is noticed to a customer database to search for caller information. When pieces of caller information are acquired from the customer database by the telephone coordination server, the exchange machine is connected to a voice automatic response device (IVR device) to acquire predetermined voice data by telephone communication with a caller, and the voice data is compared with voice data included in the caller information by a voice recognition server to generate caller candidate information having priority levels. On the basis of caller candidate information, caller information of a first candidate is displayed on an operator client, candidate names of second and subsequent candidates are displayed as a list, and an operation of selecting a candidate in the displayed list is caused to change the caller information being displayed at the present into caller information of a selected candidate.

Abstract: A switching system which can easily reconnect a call to an original call path even if an original call state is disconnected at a time of transferring the call to another outside line or extension is presented. In a state where a call path between an outside line (or first line) and a call center (or second line) is formed, the outside line is connected to an outside line transfer destination (or third line) when a transfer demand from the call center to the outside transfer destination is received and the outside line is automatically reconnected to the call center when the call between the outside line and the outside line transfer destination ends.

Abstract: An inorganic constructional board for use as wall backing material or the like comprises a middle layer portion (1a) formed mainly of inorganic foamed material with an adequate quantity of fibrous material and binder added thereto, and outer layer portions (1b) placed on both surfaces of the middle layer portion (1a), the outer layer portion being formed mainly of mineral fiber material and inorganic powder material with binder added thereto. The middle layer portion (1a) has a specific gravity of less than 0.4, and the outer layer portions (1b) have a specific gravity of more than 0.7. Therefore, the board is more lightweight than a plaster board and has performance characteristics equivalent to or better than those of the plaster board.

Abstract: A ring trip detection circuit detects an OFF-hooked state of a telephone receiver during ringing of a telephone set by detecting a change in a voltage across two terminals of a transmission resistor through which a ringing signal is supplied to the telephone set from a ringing signal source.
